Nice BCG

Nice doing business with Primary arms. As a gunsmith I never worry about customer service with PA.

Bolt carrier group is nice and tight, functions flawlessly and I will be getting another soon for my s&w ar15. Primary arms was a measure to deal with, and teleported to my door in just 3 days halfway across the country
Quality products and services
by kyle
Building my current project I have searched for quality and best deal combined for many of the parts. In doing this primary arms has now become my "go to" site as they offer such a wide variety and have great turn around.
Great Deal

Fail Zero Review
by Travis Eller
Excellent BCG, finish is amazing. Very slick very consistant. Feels great with very minimal lubrication. Smooth and all great internal parts and proper staking. This is one of only 2 BCG I recommend.

Good looking product, staking could have been a little bit better. This was my first purchase from Primary Arms. Excellent shipping, good communication. Very pleased and will buy from again.
Perfect for the Price!

Got it on sale for $109 for my new built; took it to the range and what a difference. Runs and cycles without issues and very smooth operation.

Fantastic product
by JDC
Have run this BCG in my RRA LAR15 for years so when these went on sale I jumped on one to complete an upgrade project on my 20+ year old EA-J15 which is now range worthy again.
Great BCG

High quality product, slipped right in. Can run without lube (I ran 500 rounds just to test it out and it ran fine), and wipes clean with a cloth. Extremely fast shipping, and great price. They cost more straight from FailZero and this is the lowest price I've found. I'll never use any other BCG's in my AR's.
Fail Zero EXO Bolt carrier

I bought this for a new SPR type build I have not yet installed it but it looks to be of good quality. I will report back once I get to use it.As always PA was quick with the delivery. Keep up the good work.
Used?
by tom
I have been waiting to try one of these Zero-Fail bolts for a long time. I finally bought this one but was disappointed when it arrived. The entire bolt has a "smokey" look. Looks similar to the stains on other NiB bolts that I have (after shooting). The carrier seems to be clean, just stained. The bolt had Carbon deposits all around the tail. I scraped off the carbon and cleaned the whole BCG. Will see how it performs when I get it to the range. It has Obviously been Used... Did not see THAT in the description.
Great product
by Clayton Blair
I recently purchased this bcg for a 300blk build and it is awesome! Great quality and very smooth. Would purchase again!
Great BCG
by Lucas Urlie
I've put a couple hundred rounds through my gun with this BCG and have had no issues whatsoever. I have never ran it without any oil, it goes against nature for me to not oil everything. But overall I think it is a great BCG and I would definitely buy it again.
