2 Black Rain Ordnance SPEC15 Machinegun Autopsies (SEE DESCRIPTION) - Part 1/2

This video is 2 hours long, so we listed all of the problems below. Both guns are 100% Factory beyond the broken parts that were replaced by the Agency (Autosear Pin & Hammer Pin). A few hundred rounds have been fired through each gun. No one has modified, disassembled, or changed anything beyond the broken pins. mentioned above.
We apologize the the background noise. We had numerous issues with our camera equipment and microphone. We hope to eliminate these issues before our next video.
We did NOT make all of the repairs I wanted to perform because the repairs were not approved at the time of the video. We are working to have the proper fixes approved. If the proper fixes are approved, we will make a Part 2 and include 4 more identical rifles.

I wish I would have seen this video sooner. I am a former builder for black rain ordnance. I worked for them as an armorer/builder for their production guns as well as customer warranty issues. First and foremost. Black Rain sources their barrels and bolt carrier groups from Anderson and Bear Creek Arsenal. While working for Black Rain, upon every barrel shipment I as a builder was instructed to line the barrels up on a table, squirt oil in to them, and take a brass brush on a drill to the chambers. I was also instructed to drill out the gas ports with a drill bit. Now I, as somebody who takes pride in their work, took care to make sure the drill bit did not come in contact with the inside and opposite side of the rifling inside the barrel when drilling out these gas ports as to not affect accuracy or durability. The president of the company, Justin Harvell. Examined me taking time on said barrels when walking through the manufacturing side. Justin proceeded to tell me that I was taking too long and that he didn’t care if the rifling got a “scuff or two” and demanded that I press through without care or attention to detail. With bolt carrier groups and barrels now being subject to the price of these rifles. I will now move on to the rails/barrel nuts. When installing barrel nuts I was given no instruction as to torque spec. “Force the gas tube to line up with the barrel nut” was the general guidelines given. As an experienced armorer this is obviously not the correct route for assembly. Furthermore, the screws that lock the rail up with the barrel nut are “torqued” with dewalt drills. Yes. Drills. There is absolutely no torque spec for the screws. And there is zero loctite applied to ensure said screws do not come loose. In addition, further in to my employment with Black Rain, I was asked to work an event out of state that I wish not to disclose at this time in fear that I may be sued or pressed with litigations if Black Rain were to find out my identity. (Yes I am commenting under an alias) Before working this event I was instructed by CEO Justin Harvell to tell any inquiring customers at the Black Rain booth that ALL parts are made in house in Neosho Missouri as well as stringent QC measures enacted that absolutely never took place. Black Rain made ZERO parts in house and outsourced everything from the absolute cheapest manufacturers that they could attain. Bear creek arsenal BCG’s and barrels came in and were laser engraved with their logo as a facade to mark their parts/guns up at a premium price. Further more. Before working this event, the sales manager called me in to his office, among every other employee that was scheduled to work the out of state event, and advised us that Black Rain was unwilling to pay us our hourly wage for hours worked at this event. We were instructed to come up with a “dollar amount” that made us feel okay with working the event in order to prevent paying overtime hours while away from home. As an armorer making $11 an hour I was instructed that the “hourly wage” needed to fall below current pay standards in order to keep overtime down. My own personal transgressions aside regarding this. I would like to inform the AR community that when purchasing a Black Rain rifle, you are purchasing, at best, a sub par, budget rifle, that’s marketed with a cool name and brand logo, horrible QC, and bad business practice not only to the consumer but to employees as well. The cerekote options they offer are about the only thing they can get right. I have long since left the company and would advise anybody who values the money they work for to be spent with any other AR company that produces legit rifles. Although this comment was long. I hope any and all who have considered Black Rain as a potential purchase will steer clear. Feel free to message me regarding any other mal practice regarding Black Rain.

[@markpaul2833]

Great info. Thanks for the comment. Bought one for 900. I do like the look of these rifles. With a couple upgrades, might be able to make it a top quality rifle without paying the 2k. I plan on building a top quality rifle first. But glad these videos were out there and good to come across this info.

@ayitsyaboi maybe with a little research, I could have saved myself $900. But I'm buying a new rifle or gonna assemble another one. But it's only $900. Will just work a few more days and get it back. If it still shoots then it does exactly what it's intended to. I can worry about the other stuff with my next build. But I plan to get a 7.62 next. DD6 or DD5. But I've seen some BCCM I like too. So will have to weigh the odds and try to get something the looks and feels good to me.

[@ayitsyaboi]

@@markpaul2833 nah I wasn't trying to be judgey or anything, it just seems like there are better options for starters that would cost less than trying to fix that one. You're essentially starting from scratch, anyway but if yours is a good example there's no harm. Upgrade what/when you can and eventually you'll have the build you want in the end.

This is what happens when the wrong people make horrible choices for Patrol Issued Carbines . Or just not consulting the right people before the decision is made . Plenty of other Manufacturers out there who are significantly cheaper that actually work as advertised. I honestly do mot know why Agencies are not using SOLGW because of their Warranty. SOLGW , Centurion or Colt would be my main choices . Colt , and Centurion will always be my 2 go too rigs . Colt has not let me down in 17 years and Centurion has not let me down over the past 12 years . Ive gotten a lot of crap over the years for saying Colt is the gold standard . .. Absolutely phenomenal video bro .thanks

[@seanwhite304]

@@privatezim3637 there is only a handful of companies who can mass produce while maintaining that known quality . Colt in their prime GWOT days was cranking out around 300 M4 / M4A1 Carbines per shift and there was 3 shifts . FNMI can also mass produce . To my knowledge Colt / Colt Canada , FNMI , and LMT are the only ones who can mass produce 500K order . Sig might be able too but still unknown how well their quality will be . TDP Colts and FNMI are pretty polished when it comes to mass production . LMT can also mass produce but if they do they will not be able to maintain Commercial market and just have to focus on Mil sales . I seriously doubt HK , Geissele or DD could even do 25k order for complete Carbines . HK did 19k order for the M27 but they had 3 years to do it . Whereas Colt or FNMI had under 5 years to do 400K order . No way would BCM be able to do anywhere close to those numbers . I've heard Hodge Defense has been getting quite a few US DOD contracts but have 0 clue what that amount of Carbines is .. I have a buddy who in LE . They switched from Colt to DD about 5 years ago . They have little over 50 officers for the whole department. They went with DDM4A1s and SWAT Officers got issued an extra DD MK18 Upper . They are Semi Auto Carbines . I'll have to ask him how long it took them to fill that order . For all I know they might of been waiting a year lol.. I'd be curious to know what's the most used Carbine in LE across the USA . I bet theres metric crap ton still using Colt . Some might still be using Colt Canada lol. I do know the FBI mainly uses Geisseles and HRT might still be using 416s .

One of my reasons for loving weaponry is the mechanical engineering involved to make them work. You provide the most in-depth information and reasoning for the how's and why's guns either work or they don't. Your obvious knowledge, experience, and expertise shows in the quality of your work and detail. I have no idea how long you have been doing this but if you don't train other armorers, you definitely should. The shooting world needs more truly qualified folks putting their hands on weapons. The long videos are great and I learned more in the last 2 1:59:31 hours than I have in the last 2 years. Thanks for your time and effort.

[@oldscratch3535]

But they're trained! One thing I've learned over the years is just b/c someone works with guns doesn't mean they know a damn thing about them. I work for a well known AR-15 manufacturer. Most of the people I work with don't know jack shit. Even the engineers don't know the intricate details of firearm design. They're mechanical engineers, not firearm designers. And they often just work on one specific aspect of a design, whereas someone like J.M.B. was an actual inventor and firearm designer. I can tell just by looking at the tolerances on prints I get if the designer knows anything about guns and gun parts. Most of the time they spec way too tight of a tolerance on things that don't actually matter.

These BRO rifles are not tacticool. They have a mall ninja vibe that just comes across as cheap and sophomoric.

Its probably a very small department with 2-3 officers. Which is even worse b/c its not that much money to equip 3 guys with good equipment. But in reality, they probably don't need rifles and damn sure don't need full auto ones.

[@YoutubeLovesCowards]

@@oldscratch3535 Agree 100%.

[@wahttehfuk]

You could spend 500 less and get a better rifle. These are way, way overpriced.

[@doktorfaustus]

@@oldscratch3535 Put another way: Anyone who lacks the knowledge to avoid BRO as a "duty" rifle I don't trust to have sufficient training to carry a select-fire weapon into tense situations where innocent civilians may be present.

@@doktorfaustus All I see with giving officers full auto is a empty mag and friendly,s being shot. No need for full auto. Good trigger, silencer and lots of range time.

love your videos unlike anything else I've seen

Just now finally getting time to watch this video. Great learning experience, thank you guys for taking the time to document it and share. Despite having been to a SOTAR class i'm always learning more from you guys.

[@johnnym5564]

I watched the whole video and will save it for reference. Have been building for 3 years and this is great reference video. Also, your wife has is a great camera operator and have patience of a saint. Many thanks.

I got a battle damage/rebuilt M4 from direct support in Iraq. They put the castle nut on backwards and didn't stake it. It jammed up at the clearing barrel coming back from a mission where we had no contact. They fixed it quickly and correctly, but I never did find who it was that screwed it up in the first place.

[@themightiestofbooshes9443]

Love these videos because it helps me diagnose problems with my first AR, which is a piston operated 6.5 Grendel. First problem I had was on the very second round. Failure to extract. Chamber had so many burrs and the extractor took a bite out of the rim! On STEEL CASE ammo! The RSO at the range oiled my rifle's chamber liberally for me and it started operating wonderfully.

[@LRRPFco52]

You should never oil a chamber. It increases bolt thrust tremendously and the case doesn't have anything to purchase during obturation.

[@doktorfaustus]

@@LRRPFco52 You are absolutely correct. Heavily oiled chamber is a big no-no. Just another example of a know-it-all at the gun range, admittedly trying to be helpful, but ultimately showing his ignorance.

[@themightiestofbooshes9443]

@@doktorfaustus Sorry, I'm a bit of a new shooter. How else could my failure to extract have been fixed? The burrs on the chamber took purchase on the steel cases and would have caused another failure to extract if I had continued. Thanks in advance.

[@doktorfaustus]

@@themightiestofbooshes9443 a gunsmith could ream the chamber, with appropriate tools. I'm afraid there's not a safe & reliable "quick fix" for a chamber that bad.

[@SchooloftheAmericanRifle]

Chamber should be gauged thoroughly to see if it meets minimum standards, cast, cast measured (for oversize). If dimensions are safe then a flex hone and polish will usually fix the issues unless it's really bad.

A long breakdown and autopsy? I believe the quote is " Don't threaten me with a good time."

[@akmarksman]

Thanks to your videos, I've been able to help my friends and family with their AR15s. My friend had a AR that would fire 1 round and failed to pick up the 2nd round. This was a newly built AR. We tried my BCG, it ran fine. We tried his BCG in my AR and it was causing the same issue. Contacted the manufacturer, got a RMA and sent it back. Got a replacement one, runs great. Wish I could afford to go to one of your classes, but I cant because of time and family. Learning about how you troubleshoot and you going over parts and how they work as a system helps a lot. Looking forward to more videos. 👍🏻

[@kenabi]

if these are 'factory', BRO is.. eh. if the agency has an armorer and they handled these to put them (or allow them to wind up in) this condition, that armorer is lazy or meh.

The Armorer is Black Rain Ordinance Trained.

[@SchooloftheAmericanRifle]

​​@@doktorfaustusI'm not joking. The Agencies Armorer did not want me to get my hands on these guns to inspect them. Said there is nothing wrong with them or the other 4 units they have. He is B.R.O. trained. B.R.O. teaches Armorer's Classes.

[@SouthValleyKnifeCo]

I'm still blown away at how bad these guns are. And I also wonder if the "armorer" who added the sprinco orange springs to the guns was just being lazy

Springs came that way from the manufacturer.

It's usually the swat guys or other high speed types that get them

[@briansmith2125]

Did some local agency "armorer" make changes to these guns, or did they come directly from the factory this screwed up?

[@SchooloftheAmericanRifle]

The answer is not only in the video but it's in the description.

Thank you for these uploads. I’m struggling to learn from a 71 year old gunsmith right now and i’m not complaining about that, but your videos are so refreshing after being lectured for an hour about how semi-auto firearms are less accurate than any other action and that 5.56 was designed by the army corps of engineers to wound and not kill because that means it takes 2-3 guys out of the fight opposed to one. Every session is painful but i’ll take free knowledge anywhere i can get it. Videos like yours seriously help me sift through and dispell the fudlore nonsense. Thanks again
