Questions & Answers
Is this Bcg High pressure tested & magnetic particle inspected? Expert Answer

The manufacturer doesn't state whether or not the Black Rain Ordnance Bolt Carrier Group has been high pressure tested but it has been magnetic particle inspected.

by Hunter, Gear Expert, January 21, 2022
can I place a 7.62x39 Bolt in here if Bolt carriers are universal? Expert Answer

Yes, the carrier in this group will fit most 7.62 bolts. You will need to check the bolt though as there is a manufacturer that uses a proprietary system so that they can use the AR-10 bolt in the smaller platform so that the walls of the bolt face aren't as thin.

Awesome BCG by D, March 26, 2019
Excellent bolt carrier group. Expected nothing less from Black Rain Ordnance. I was surprised by the fast shipping, and also the quality of the BCG. The nickel boron finish is amazing. When I took it out of the package I just looked at it in awe.

Smooth BCGs by David Kemp, Verified Owner, October 21, 2021
I own two of these in a Gibbz and Stag upper, respectively. They’ve ran smooth through hundreds of rounds at a time without relubricating them. Very little in the way of wear. The NiB coating is slick and durable. No complaints from me.

I have this installed on a left handed AR pistol and it’s smooth, easy to clean, and functions flawlessly. I run it dry no lube and when it needs cleaned oiled wipe does the trick every time. I haven’t run much steelcase thru it yet but it does cycl...

Lefty nickel boron bcg by Lefty, March 24, 2019
This was the only left-handed nickel boron BCG that I could find in stock. Thanks optics planet. I used some strike hold oil on the BCG and inserted it into my Stag Arms rifle. The fit was snug and the bolt moved silky smooth. After placing a hundred...

left handed by Russell Cherry, Verified Owner, February 23, 2022
I haven’t got a clue on how it works. I bought it as a gift for a friend and he hasn’t finished putting it together with the left handed upper I gave him to go with this! As far as I know it will work just fine…but I really don’t know for sure!

Rude customer service by MarineOne, November 3, 2018
Hard to find a quality left hand BCG. I should've went with a rock river phosphate LH BCG but found the BRO BCG on a deep discount online. Rule of thumb, buy cheap you will end up buying twice. I had multiple failures with this BCG; FTF, FTE. Had mul...
