Great purchase for the price—runs extremely well in my new 40 caliber AR!
Have not finished my build, but it seems to be a good quality I'm and please with the price if it works as good as I anticipate, I will buy more!
Bought this for a .40 S&W 16 inch AR platform and runs flawlessly. I have since built a 10mm 16 inch AR platform and it continues to work flawlessly.
Well made with a good finish. Worked perfectly in my AR40 40 S&W build. Would buy again!
I bought an AR PCC in .40S&W and had feed problems on the first round. I replaced the cheap bolt with this one and no more feed problems! Thanks White Label!
Excellent value. Looks good. Fast Shipping.
Perfect works with folding stock adapters and affordable
