I bought this BCG previously and I had to take it to be staked at a local gunsmith. Are the BCGs visually inspected for light staking before shipping?
Skips on May 7, 2018
BEST ANSWER: Its hilarious how much importance dudes give to the quality of the staking for various bcg's. They don't own a caliper or mic but suddenly become QC experts...its the one thing they feel qualified to evaluate so it becomes everything...
WHEN will you have the nickel boron bcg back in stock?
Carlos B on Apr 21, 2018
Is the bolt Chrome plated and is the internal side of the carrier plated Chrome plated????
Is it high pressure tested??
What material is the firing pin made from??
Ronnie G on Apr 12, 2018
BEST ANSWER: Not chrome! Nickel. And they are the only way to go. I use several in long range 800 yd ARs and they never fail. Always keep clean and lubricated and they will last longer than you will!
Is this NiB BCG "M16 cut & full auto rated"?
Larry M on Apr 12, 2018
BEST ANSWER: It is a full auto profile. That's all PSA sells.
Is this HPT?
WWIII on Apr 12, 2018
BEST ANSWER: .........Palmetto: "pretty sure they are HPT" is not a good answer. You can verify if it is HPT or not....."pretty sure" doesn't cut it....
Is this BCG full auto rated?
Larry M on Apr 12, 2018
BEST ANSWER: Yes the carrier is milled as a M16 style so it will work on full auto if you have proper tax stamps and auto FCG.
When do you anticipate these be back in stock?
Tank T on May 29, 2018
BEST ANSWER: Check back on the 1st...

Does this have the PSA logo? Pics dont show one so i just want to confirm.
Chris N on Jun 16, 2018
BEST ANSWER: I purchased 4 NB BCGs. The NB BCGs I received did not have PSA logos.
Can the nib bcg be polished?
Jay K on Jul 6, 2018
BEST ANSWER: As delivered they are smooth as butter, and just about too shiny. So far they have been very easy to clean with no visible staining. We have run one over 1k rounds on a suppressed AR, still cleans up very well
What is the difference between this one and SKU 516445123?
Sean F on May 22, 2018
BEST ANSWER: i just looked at the the other sku numbers and compared them i really did not see a difference between the sku numbers there really the same bolt carrier. the only thing i can think of is there were ran on different dates or ran on different job numbers so there made them under different sku numbers for dates and/ or job numbers
I know bolt is 9310 steel, what type of steel is the bolt carrier?

Can this BCG be used in a .224 Valkyrie upper without any hitches? Thanks!
lonestar on May 9, 2018
BEST ANSWER: To answer your question no. The bolt itself needs to be for a 6.8 spc. so the bolt face wouldnt work. Everything else would function great if ur willing to switch bolts.

scubabear on Jan 15, 2019
BEST ANSWER: Yes. I threw it in a build for a guy and haven’t heard any complaints

Ron L on Jun 8, 2018
BEST ANSWER: I have purchased several of each from psa and the only difference I this one is it’s nickel boron coated, I’ve seen some say there MPI but I’ve seen no such marlings on the bcgs
Would this be a good upgrade for my stock SIG M400? (new guy)
Christopher W on Sep 1, 2018
BEST ANSWER: It would be a good upgrade for practically any AR15, including your Sig M400. These are great bcg. But I own a Sig M400 and it is good to go as-is. Your call.
Just want to confirm that this Bolt Carrier will fit my 300 BLK 10'5 pistol build for one? Second when with this BCG be back in stock?
