The BCG is great and as describe. I haven't put it through the test but I'm sure it'll hold up. Shipping from PA was extremely fast also. Thank you.

Quality product

I work on and sell a lot of AR type rifles at my shop, Fail Zero makes one of the best and most reliable BCGs in the industry!

slick bcg

This thing is slicker than glass.Satisfied

Poor staking job

by

Bought this bcg. Looks great and feels wonderful. Cycled 150 rounds and the gas key came loose. Luckily I stopped in time. The staking job is done poorly. PA was great on shippingetting as always.

Great BCG, good deal.

by

Beautiful finish, almost too pretty. Works great in 3 rifles I tried. Happy with the price. As always, happy with customer service from Primary.

Buy different

by

Came and looked like package had been opened. Fit and finish was unacceptable. Logo was unreadable Sent it back and got A WMD.
Much better group

Really?

by

This is my 3rd and LAST FailZero.
Loved the 1st two .
This last one the stake job is horrible, and the bill board "made in USA" cut into the side. I dont even know what to say about that. Clearly NOT mill spec.
If i paid full price it would be on the way back for a refund.
Being it was a black friday deal....
I may still return it....

Smooth as silk

Had a gas ring blow out on my Mil-Spec Black Phosphate BCG causing the Bolt to jam hard. Decided to look for a new BCG and ran across the Fail Zero during Black Friday sale. At 99.00 this was a superb buy. Installed in my AR and ran a couple of hundred rounds through it with zero issues. I am old school so YES I did lube this the same way I do all BCG's, They may say you can run this dry but I would not take the chance. Also replaced the 3 stock gas rings with a JP one piece ring. Very happy with this product and the sale price on it.

works just fine so far

by

Mine works sweet! But not as shiny as I thought it would would be but oh well can't complain when I paid only a fraction of the cost it use to be

Do not buy.

BCG kept jamming on me for my new build. I took it out by disassembling the buffer tube and had the rangemaster (retired marine) help me look it over. He lubed it up and we put it back in; fired 18 rounds and it jammed again. I threw in my S&W M&P 15 bolt and the new build functioned flawlessly. I would not recommend this to anyone, spend some more $ and get a decent BCG.

Other thoughts: fail zero? lol

From PA: Fail Zero did have some poorly staked BCGs make it into our inventory. They immediately flew someone to our location who reviewed and properly staked all our inventory. If you are having problems with your BCG please contact us right away so we can remedy.
