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!
WHEN will you have the nickel boron bcg back in stock?

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 NiB BCG "M16 cut & full auto rated"?
Larry M on Apr 12, 2018
BEST ANSWER: I've run full auto on a few of these. No failures after 5k plus rounds.
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.
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: If you cannot handle staking a bolt yourself, i don’t think you should have an ar.
Will the 556 bolt also work with the 300 bo?
Jayman on May 7, 2018
BEST ANSWER: Yes, they actually use the same case. The difference is at the case neck which is expanded to 30 caliber. The case rim is exactly the same. You can make 30 BO cases from 5.56/.223 brass but it is easier just to buy the 300 BO brass if you reload.
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.
What is the difference between this one and SKU 516445123?
Sean F on May 22, 2018
BEST ANSWER: For a few more dollars you will also get a charging handle

Best deals for the money
This is the 2nd BCG I own with PSA never had problems. best deals out there, these easily run 180+ somewhere else.

Much better than I expected
I found this BCG on the Daily Deals at a great price with free shipping. I've been wanting a NiB BCG for a while to finish up a PSA stainless barreled Dissipator upper that's been in my garage for over a year. I place the order and two days later the big brown truck of happiness delivered it to my door. The finish and machining on this one are the best out of the 10 that I own. I will definitely buy this again and recommend it highly.

Sweet Ass BCG!!!
I now have two NIB BCGs I installed the POF cam Roller pin and gas key on. I like this one because it actually looks as if it were polished whereas most other NIB BCGs look to be spray coated... Once again and I reiterate SWEET ASS NIB BCG!!! I treasure this one the most.

Excellent Ni Boron BCG
Excellent quality and the most reasonable price out there. Of course they’re so busy it takes a little time to get it, but once I received it, there’s no other I’d buy! This is my second one and I look forward to getting another one!
