Any Problems With This Bolt Carrier Group Deal?

[26 Inf]

What do you think?

http://www.brownells.com/rifle-parts...prod77791.aspx

$84.99

SPECS: Fits AR15. Carriers are machined from 8620 steel and properly heat treated. Bolts are machined from 9310 steel, are shot peened and magnetic particle inspected.

Kits include: AR15, gas key, gas key screws (2), stripped bolt, extractor, extractor spring w/ insert, extractor pin, ejector, ejector spring, ejector pin, bolt gas rings (3), firing pin retaining pin, firing pin and cam pin.

I'm asking because the price seems good and I like to put things together.

I would use that BCG all day long, It would be a fun little project to assemble it too.

9310 "technically" isn't mil-spec. If that doesn't bother you go for it.

You're paying $85 for a semiauto carrier and 9310 bolt, and you get to put it together. You could get better specs fully assembled from AIM Surplus at the same or lower price.

Other than that, it looks OK. From what I've read, there is more to properly installing the carrier key than just bolting it on.

Non-mil-spec BCGs are quite cheap and plentiful right now. And it's not an awful time to pick up a BCM or DD for slightly more money.

Thanks for the link, I've never done any business with them.

Glad to help. I've got 1k rounds on a competition upper using the nickel-boron coated flavor of that same BCG from AIM. Not a long enough test to say it's especially good, but long enough to shake out any basic failures. For a non-critical gun I think they're a good value. I will also be testing their nitride-treated v2 BCG with a Faxon barrel in the near future.

I have had good luck with toolcraft BCG they are a direct military replacement for the colt BCG. Plus you do not have to assemble it.

I just ordered 4 of these myself. I would go with the Toolcraft before I did an unassembled semi carrier.

I have personally seen armorers replacing USMC M16A4 BCGs with Toolcraft 1B1B6 and I have at least one approaching 10,000 rounds that still works excellently.

This is a good example of "legitness". Toolcraft does indeed sell milspec BCGs to the military, and that can be evidenced because their name isn't "Navy SWAT SEAL Team 11 Zombie Invader Six".

Good enough for me.
