[HordesOfKailas]

Any experience with these BCGs?

I need one for my 5.56 AR and these are on the lower side of the price spectrum. I've seen people talking shit online but some seem to like them. I trust you guys more than some randoms, so tell me what you think.

I'm also open to other recommendations. Just trying to keep the BCG <$100.

Interested in this as well.

PSA recently had BCG and CH combos for under $100. I need one for my 3 hunnit blackout build but haven't purchased on yet.

Typically, the AIM phosphate BCG's have been good value for money.

No experience with the NiB units, simply because I don't use them for my own reasons. No input on the melonited offering either.

Of the 2 the nitride is better, but I would not get either. NiB sucks

PSA has Phosphated/Chrome Lined for $100.00

Just the man I wanted to hear from. Thanks for yhe lead. Will probably order it.

I have one of the Nitride versions. I have seen no problems with it so far ( approx. 500 rds.). Picked it up really cheap from a guy at the range that was selling a bunch of new AR stuff he wasn't going to use. It does clean up pretty easy.

The AIM BCG uses 9310 Tool Steel for the bolt, and the PSA offering is using Carpenter No. 158 steel for its bolt. For better or worse, I have always gone with the Carpenter steel.

[EDIT forgot, the PSA BCG is chrome-lined]

AIM had issues with gas key staking in the past.

Another couple of nails in the coffin.

Chad beat me to it.

I have two of these BCGs in rifles (one a 16" carbine gas 5.56 and one an 8.5" pistol gas .300BLK SBR) and they have treated me well. I've got a third in the safe as a spare.

If you watch the price on them, it fluctuates regularly. I've gotten them as cheap as about $70 each in pre-Christmas sales, but they're frequently down to $80 or so in regular sales.

the AIM phosphate BCGs are also chrome-lined, and none of mine (half a dozen?) have gas key issues--be it torque OR staking. not that either is a difficult fix, of course, and I've even seen Colt BCGs that weren't torqued properly.

it's not about one brand or another's online reputation, per se....any of the "standard" units out there (BCM, Colt, PSA, AIM phosphate, Toolcraft) will work fine. It's more about whether you know what to check when it arrives, and how to correct any issues that may arise when checking it.


The only thing to truly avoid is anything that comes with a single-piece gas ring. That's just asking for trouble.

Just want note that the BCG clandestine linked is on sale for $89.99 shipped. Grabbed mine up just now.

 

[goterps]

I have the second one of the two you posted the black 9310 BCG, it performed with no issues at the range.

I was trying to decide if I should go AIM again for my current in progress build or maybe do a BCM BCG.

I ordered 4 of them last week. One for a current build the others for the parts bin.

I'll toss in Cryptic Coatings into the mix. Commercial side of Toolcraft (Mil OEM)

$110 for mang phos or nitride. http://www.crypticcoatings.com/coated-bolt-carrier-group/

Unfortunately they sell out very quick.

If my experience is any indicatior, you'll be happy. Well over 500 rounds with no issues. Can't beat it IMO.

I've not seen many reviews about these. Are they any good?

 

[vgplayer]

I haven't heard anything bad. They have zero marketing AFAIK. The finish on mine was flawless. Made me think there was something wrong with my other BCGs.

A quick google of "toolcraft bcg" yields plenty of information. They're superb, and the likely OEM for a lot of other companies out there.
