What is the weight of this BCG?
Joseph H on May 5, 2018
BEST ANSWER: Not light. Well made and slick, but heavy. I have three at home. I will weigh one. Not recommended for lightweight specialty build. Highly recommended if weight is not an issue.
Will this BCG function with a .300 Blackout upper?
Ron P on Apr 18, 2018
BEST ANSWER: Yes, a 5.56/.223 bolt will work with 300blk being that 300blk is based off the necked up 5.56/.223 case. So bolt, mags and lower are interchangeable, just different barrel.
Were is it made ?
Jeremy H on Apr 27, 2018
BEST ANSWER: Made in the USA.
Is the bolt carrier chrome lined?
Kevin F on May 28, 2018
I assume this bolt will also work for .224 Valkyrie builds as well? Thanks,,,,Ed
lonestar on May 5, 2018
BEST ANSWER: This BCG will not work in .224 Valkyrie as their shell is a 6.8SPC necked down to .224. The .224 needs a 6.8SPC BCG.

Does it work with piston driven actions?
Andy H on Jun 20, 2018
BEST ANSWER: Gas piston ARs need a specific bolt carrier key, not the standard direct gas impingement key. This bolt should work fine as long as you install the proper key on top of the bolt carrier.

Smooth action
I'm not sure that this improves performance as much as some of those super expensive BCG's, but this is an improvement over the standard oil-spec BCG. It has a very smooth action and feel as you pull the charge handle back. I've only put a few hundred rounds through with this BCG, but it was easy to clean afterwards. Overall I like it!

Good bcg at a great price
I have a collection of Fail Safe BCGs and this one is definitely comparable. No issues after 300 rds so far. Good to go

Bling Bling for your Build!
For $89 shipped on sale, can't be beat for the price for a bolt that is HP/MP tested C158!

Lube it up, place it in your favorite rifle and keep your standard BCG as a spare! Pick a couple up at that price, if you're spending more you are just paying other companies more for their name - PSA is the best!

Slick good staking. Not as shiny as it thought but a little polish should fix that.

It's a nickel boron!
Beautiful bolt carrier group. I don't know what else you can say about this. It does not come with the Palmetto Armory stamp, but who cares! It's a nickel boron, and it's a hundred bucks, and did I mention it's a nickel boron!

Very Good Value
For the price it would be extremely difficult to find a better bolt, free S&H is a bonus.
