SMOOTHEST 9mm Upper! MEAN Arms Bearing Delay

[@MEANARMS]

Thanks IV8888 team! For the LRBHO, anyone can swap to a different Lifter to ensure the BCG cycles fully. Every Bearing Delay upper includes 2 Lifters. Seems like Eric is shooting the standard K Lifter. Changing the Lifter will adjust the dwell time to make the gun run more aggressively or slower. We have Lifter designed to make sure the upper will cycle with really low power ammo and we have Lifters designed to reduce recoil for higher power ammo (like +P+). Lots of people curious about Glock magazines... yes, the upper works with every Glock lower that we've tried. You will need to remove the ejector from the lower, which is usually a couple of fasteners. As Eric showed, we have LRBHO with our magazine systems. For a Glock lower setup, LRBHO depends on the lower... so some will and some won't MEAN currently has 10% off all orders (including the upper) with code: INFLATIONSUCKS And, we have a layaway option of the upper Every upper includes lifetime free service and our Lifetime Warranty - if you ever have a problem with the upper, we will fix or replace it

I have the 9mm uppers from CMMG. I use your conversion mags adapters for that upper I was wondering if you might possibly be coming out with a mag/ conversion kit for the CMMG 40 caliber uppers. I would also like to know if you’re going to come out with a 40 caliber upper, that would use a standard lower.

[@festerallday]

I just shot an mp5 in Vegas. It's recoil was way more aggressive than a couple of tuned blowback ar9 using MEAN arms mags I've shot in the past.

I like mean arms mags. Great for Hawaii because it's not a pistol mag and therefore not subject to our pistol 10 round limit

[@bestyoutubechannelever3206]

If SCOTUS strikes down magazine capacity limit laws, you won't have to worry about that anymore. There are seberal challenges to those laws right now.

[@festerallday]

@@bestyoutubechannelever3206 Hawaii don't care. They pass bad laws knowing that it will take a few years to get them scrubbed. That way the duchebags... I mean politicians can say that they voted for the safety of the people.

[@Rushifell]

There are 5 different lifters that you use to tune the rifle, the best choice is determined by the ammo you're using and shooting suppressed or not etc. If you have an issue with cycling changing the lifter can be the difference. I own a 16" of this gun. I had some minor issues to work out and had a fantastic experience working with MEAN on it and got incredible support from them. It now runs flawlessly. The upper comes with 2 lifters but there are others, a lifter changes your dwell time with the bolt closed by changing the angle on the face of the lifter which changes the force needed to actuate the locking mechanism. I built mine out to be pretty fancy and i love it. The endomags work great too. The issues i had weren't related to the upper itself and un the end turned out to be the captured buffer i was using, switching to a normal h2 and flat spring fixed it up entirely. I am trying another captured system this weekend (hopefully), but had an issue with the armaspec h2 captured buffer.

[@ZEE0H6]

I had issues with the Armaspec gen 4 SRS buffer as well. The small secondary spring is what provides the preload and it wasnt enough pressure to seat the BCG. I made a nylon spacer to sit behind that spring to increase preload and it worked. I ultimately switched it out to a standard Tubbs flatwire and kynshot and that thing is smooth.

[@Rushifell]

@@ZEE0H6 nice, mine was a gen3 H2. A normal flat spring and H2 worked just fine. I now have the unrivaled duty buffer in there which is carbine weight and haven't had any problems so far but only about 250 through it since then.

[@RedTSquared]

Okay, this looks like an awesome system but for $1500, I can take a little heat and recoil. Very cool upper though! If I had the $$$$ I would definitely roll one of those. Thanks for the Video!

[@wombatt360]

Haha, Eric looks like John Goodman in the movie The Big Labowski with that vest on. "Mark it zero!!"

[@danielhess39]

Great review!! Thank you👍🏼

[@AllAboutSurvival]

The use of ball bearings for delay instead of traditional methods like rollers or rotating bolt heads truly enhances the smoothness and reduces recoil

[@tuculoguey3530]

Great firearm ,ate all those round and said "more please"

[@saturn6409]

1500 with a polymer handguard

[@cl4998]

Yeah, wtf is that about?! Most manufacturers skimp out, use inferior alloys of aluminum (six thousand series) rather then going with 7075 t6, but they can be made serviceable, unlike a polymer handguard. I'm not a big fan of any wear part being made from polymer, just due to the legislation that's been getting passed across the nation lately.

[@coal_tactical]

im fine with the handguard its just cmmg rdb bolt and barrel is only 380 just bought it a week ago and a simple handguard slick upper combo was 150 max, its just way too much in comparison to its competition

[@PoormansMachineGun]

Eric you should get the HiTec Arms AR9SD upper for T&E. It features the Mean Arms bearing delayed BC with HTA MP5 SD suppressor!

[@reedwally6143]

I would love for you to compare this vs the Maxum defense roller delayed buffer and do a meltdown of both

[@BillHimmel]

These glasses look so 70ties! But I love it! And a cool gun! Keep it up!

[@TheBdb869]

CMMG has the same type of insert for P-Mags. CMMG also has a rotary delay blow back 9mm upper. I have been very happy with the reliability of the CMMG.

[@blackfacegaming191]

Those have wear parts though right

[@festerallday]

That's the same mag from MEAN arms in the CMMG

[@festerallday]

​​@@blackfacegaming191the CMMG version does not have an ejector built into the mag because there is one in the upper on the banshee. But yes I have worn out the ejector in the standard version of the mag inset too. MEAN replaced it though

[@cl4998]

Way better alternative to this rifle. The fact they skimped, and went with a polymer handguard is a joke. I'm sure they will use the weight justification, when its really about profit margins. Its difficult to make a rigid, and relieble aluminium handguard; polymer shouldn't be considered for a handguard or any wear part material, especially one with a rail.

[@YouTubeflakeland]

Mean arms did it first. Cmmg just followed

[@bsh668]

Why is there a piston on the suppressor on a fixed barrel sub gun?

[@williamboggs1682]

Running a booster on the can?

[@bmartin863]

I wonder what just the upper costs?

[@thelittledetailscr7231]

You can get a whole cmmg gun with the roller delayed system for that price. Not just the upper.

cmmg is a radial delayed system.

[@jasonmcclish2580]

Who makes that anti rotation clamp on the hand guard? Great video guys.

[@ZEE0H6]

It’s part of the handguard. The handguard threads onto the proprietary barrel nut and those pieces clamps it onto the receiver.

@@ZEE0H6 does that include the clamp that bridges the top Pic rail between the upper receiver and hand guard?

I'm new at owning firearms, so, is that what a suppressor is supposed to do, because that's cool!

[@MrWhatdoyouthinkof]

The can is moving like it has a piston spring in it for use in a tilting barrel pistol . Can that can be changed to a fixed spacer such as what the Silencerco Osprey uses ?

[@musician445]

Gambling using that pistol can with a booster in it i see lol. Seems like it did okay though! This bearing delay thing is super cool, I'm stuck between it and the CMMG radial delay.

[@theagenejean768]

Nice job

[@nebick27]

I read up on this system, they state that you need to tune for subs etc. with different bearings

[@MEANARMS]

yes, the Lifter can be changed to adjust the dwell time to optimize the system but the standard Lifter works with many different setups as shown here

[@garyh7949]

[@johnnyk5]

please compare this to the Angstead MDP9

[@TheCosmicGuy0111]

Nice

[@nicholasgrover2993]

you not running fix barrel spacer in the can its moving a lot?

[@ShizawnSanders]

What about a best millimeter version? $1,500 for a upper only is a shit ton for 9mm with so many offerings of full guns in 9mm that are good. I can MAYBE see spending $1500 on a 10mm upper if its dead nuts reliable and gives the best recoil ruduction of what's already available from Stribog and CMMG.

[@bryanduchane2371]

The barrel actually moves back and forth. I'm sure it's designed that way, but I'm not sure how or why....

[@wesleyroberts7119]

I think thats the piston on the silencer your seeing movng.

[@robertkoonce8365]

It appears to be the booster on the can moving forward and back. The barrel.should be a solid mount like any other AR upper.

[@joshlanter0928]

The suppressor has a spring loaded mount

[@cl4998]

Why would you put a booster on a rifle suppressor? Lol.

[@BAdventures]

It's a recoil booster or Nielsen device. Some handguns need the extra boost to cycle reliably with a suppressor. The extra weight on the barrel can even stop it cycling. A fixed barreled gun like this doesn't need it. But cool we got to see it working on this video.

[@pc-snoozing9724]

Why does suppressor move forward when firing a round?

[@zap7759]

How about something other than 5.56/9mm/12ga/.22LR for once?

[@James-x5w9c]

Bro, why are you wearing the Groucho glasses 😅

[@seanhudson7549]

What is that little anti-rotation device in the pick rail at the back of the handguard?

[@ZEE0H6]

There’s one on each side. The handguard threads onto the proprietary barrel nut and those pieces clamps it onto the receiver.

[@robertkoonce8365]

Not too bad as your head was obscured by the smoke fo the ejection port. Lol

[@Joe-hz1nw]

Cool, but $1,500 with a plastic hand guard? You can get a MP5 clone for $1,000 if you look hard enough.

[@cerneysmallengines]

how does it compare to the CMMG 9mm system?

[@ZEE0H6]

No comparison, the MEAN is way softer and flatter shooting than the CMMG radial delay system.

[@cerneysmallengines]

@@ZEE0H6 I have 2 of the cmmg AR9s, they are incredible to shoot, that leaves me very anxious to get my hands on this

[@ZEE0H6]

@@cerneysmallengines highly suggest picking up some additional lifters to tune it your ammo, spring, and buffer setup to maximize the potential of the system. It’s a huge reason why I went with this over the CMMG. I’m using the P lifter with factory 115gr.

[@cerneysmallengines]

@@ZEE0H6 so, my 2 setups are as follows 12.5" cmmg 9mm 8" cmmg 9mm the 12.5 has a standard style cmmg lower that I run endomags in. the 8" is on a PSA AR9 lower that takes glock mags the 12.5" is running the normal ar15 buffer spring with an ar9 weight the 8" is running a standard buffer weight with an ar10 spring in it. both have been incredibly reliable, the 8" shoots a lot softer

[@seanhudson7549]

Will it work with a 9mm Glock lower?
