Blemished full auto BCG (Milspec Carpenter No. 158® steel bolt
) for 99 bucks. Seems like a pretty good deal.

Is this a good deal if I just want to have a spare BCG on hand... and if I don't need full auto?

 

[huesmann]

Yes, it's a good deal. Even if you don't need full auto.

 

[davesomethin]

yeah, what do you make of that? if its truly just cosmetic, who cares, right?

 

[Arcamm]

I don't see any of the usual "testing" specifications that I see on most BCGs. I wonder how good the quality is on these.

FWIW, PSA is refusing to answer this direct question. Read into it what you will.

Thanks, are these bolts high pressure tested and magnetic particle inspected?

There was some ruckus over PSA using MIM gas key bolts or something last week. They got called on it IIRC

for 99 dollars what can you expect

It's not the first time this happened. They also have a habit of selling mislabeled items.

They are a decent company but they need to stop the antics if they wish to become a great company.

Well, they got 99 from me. I guess only time will tell if I got hosed.

What is "MIM"?

Metal injection molding... Usually as opposed to machined.

I think the best thing going for PSA is their proximity to FN. They have great deals on FN barrels

Not saying anything bad about PSA; but here is a BCG for $135 from Joe Bob's and it is MPI tested.

[davesomethin]

Pardon the fifty questions.. The Joe Bob bolt is labeled as:
" 9310-Case hardened, Shot Peened" ... How does that compare to
"Milspec Carpenter No. 158® steel" bolt?

I ordered my complete upper during their July 4th sale and it arrived Monday the 22nd.

 

[Americus]

my whole rifle was built with PSA parts... Seems great to me, a nice A4gery

 

[Arcamm]

Here's my PSA upper. I dropped the extra hundred bucks for the MI floating hand guard.
It's mounted on LRB lower, CMMK LPK, Brownell tube and buffer, and Colt/Rogers stock. The handle is a cheap piece left over from when I had an ATI stock on my Mini 14.

How's the fitment? Any wobble between the upper and lower?

Yes, more than I like (which is any), but not much more than my Colt.

I'm not an Ar expert. I don't know what's acceptable and what's too much.

I've read everything I can find about that topic, and it's not clear. I've heard plausible arguments both ways. 9310 is deemed acceptable though, and in the end other things end up mattering more (like heat treat). Only thing that is clear is that 8620 is inferior to both C158 and 9310. Anybody selling 8620 bolts is selling shit (8620 carriers are normal).

AIM has some 9310 bolts as well.

Honestly, most people will never shoot enough to see the difference (even with 8620).
