I currently run an Iron City Rifle Works BCG for my SHTF/Home defense gun. I've been very pleased, it's pricy but has functioned flawlessly in my .300blk 8" pistol. Super low friction coefficient, literally wipes clean and is super smooth even after a long range day

Ive ran that palmetto for maybe 500 rounds. Did great. Until I put a binary in mine. I figured out it was pretty easy to Fump Bire if I held the trigger on the break. It didn't take maybe 3-4 mags and the "staked" gas key came loose and went into single action. I put it back together best I could and locked the bolts every way I could come up with. It works for now. For $5 you can get that BCM extractor o-ring kit to pretty much make it last forever. I have a $240ish bolt in the mail right now so I have one Id trust more. I just wanted to get a better nickel-coated one really. Word around here is those Fail Zero axo coated are the best but they didn't have the black in stock that I wanted so I went with another brand

[@whatfreedom7]

Wolff has a heavy duty or extra power extractor spring also.

Thanks for a bunch of good information. Some of my friends I shared this with ask me to a month ago about some of this. You just backed up what I was saying.

Do you have a list of all these companies? The transcript frequently cannot always understand what you are saying, so it guesses. It would be nice to have a list with these parts linked (unless I missed it).

[@jeffhudson2346]

Shot peening is another form of work hardening a part. The most common work hardening process most are familiar with in AR 15 land is cold hammer forging.

[@pistolpete6321]

Great video, really informative!

[@stephanarizona9094]

It is pretty interesting that you can take 2 BCG, same specs, same everything, one can run like crap and the other one is perfectly fine. Ive been lucky but have ran into a few that I was like WTF is going on.

[@Impossibly-Possible]

I buy the ones PSA sells for 99 or ide go with POF as they make the BEST PERIOD, but the micro best ones are top regular bolts and the PSA 79-99 dollar ones are great. POF makes the only firearm I would buy that needs NOTHING to be duty war ready.

Peening actually puts the part under compressive stress, prohibiting the formation of cracks.

[@bradleymckinney83]

I've always likes spikes tactical... been really good rifles, and bcgs.. especially since they started making everything in house. Have 3 rifles 1 with phosphate bcg, 1 with nib bcg, and the latest bcg specs was nibx and different tool steel. Not mil spec, but better, stronger, than mil spec if that makes sense.. I love it and u can def tell the dull finish of the nib and the smooth brighter shiny finish of the nib x... any way that's just my 2 cents.. all the company's make great bolts these days..

[@dtown214north4]

SP4 coating is something you should definitely try out sometime. Awesome stuff!

[@Jimmykid3]

Shot peening relieves stress in the parts it has nothing to do mag particle testing

[@snowkrayze21]

In this case I would say it induces stress to help reduce crack propagation. It is used for different results in different situations.

Also run a BCM bcg. over 5K rounds still running strong! I've had one milspec bcg fail on me in the Army, it broke lug on bolt.

Get to the question….on their site there’s Large Frame and Small Frame BCGs. Which do I go with?

How could there be an increase in accuracy with the Kali-Key, it's the same bolt and carrier? BTW I have one, but I use it to make my AR single shot with a silencer. Never thought of it as making the gun more accurate though. I did however do something interesting, I removed the gas rings to make it cycle easier by hand.

[@FreedomInc]

With properly staked gas key bolts,it really serves no real purpose. You domt hear about broken bcg's. The bolt is the part that needs to be solid and by far the HM defense HMB battle bolt is by far the best on the market. 4 years since it was first designed and they havent had not even one come back broken yet. Not even in military testing.

[@joesapienza8121]

@@FreedomInc ... That's your opinion. Having served 34 years as a United States Marine and having put tens of thousands of rounds through the M-16 / M-4 platforms , I've seen plenty of bolts fail. POF has a bolt with an excess of a million rounds of high pressure ammunition through it and it still chugs away like it's brand spanking new. Staked keys can still loosen , regardless of how well they were done. POF submitted their BCG to the military as well and it exceeded their endurance testing ten fold but was not adopted for one simple reason , price. Anyone knowing how military contracts work , should also know that while the part, weapon , ect. must meet certain criteria, price plays a very big part on purchasing as well. I'll stick with my POF any day of the week. Perfection doesn't come cheap.

[@EeZ3-808]

Couldn’t agree more. I’ve had my POF for almost 10 years and NEVER had a problem with it. Still runs like new. Aloha!

[@zakmichael]

I've got a Lantac in my BCM rifle and it works as you would expect. It has some features for running suppressed that are beneficial. Never had an issue and it cleans up easily. I don't think you need to run a $250 BCG but it certainly doesn't hurt. The BCG is the heart of the rifle. If you were going to have 2 key items it would be the barrel and the BCG.

[@HannibalTX]

Don't forget the buffer. Proper functioning is a balance of all three to avoid smooth functioning without a recoil bounce. There are vids in here for the proper weighted buffer and there are about a dozen different buffers for full automatic, M16, AR15 and M4s. If you change bolt groups and go to a heavier barrel (or a longer one-20") you will need to address the buffer.

[@HannibalTX]

Sorry for the typo. I meant to say "Proper functioning is a balance of all three to ensure smooth functioning without a recoil bounce."

[@prongATO]

Exactly what I am struggling with while doing a new upper. Going to go BCM upper, MCMR handguard, Ballistic Advantage Premium 223 Wylde 14.5 barrel, et al. I have had great experiences with NP3 but not many people make them. Is the Guissele worth it? I’d really like a BCG that’s easy to clean. I am disabled and would rather spend more time shooting than cleaning.

The underlined F is only ever on the bolt, and it just means they approved of it and it went through the mandatory 45 round test for the military.
