Perfect BCG

by -

I'm currently running 3 of these BCGs in different builds and they run flawlessly and never have had any issues and cleaning is a breeze!

nope.

by -

had to stop using it because the carbon stained it so bad the lube didnt seem to work at all anymore within a few months use. Took for ever to clean and basic cleaners seem to make the finish worse and eat threw it. So now it sits in my junk pile. Need to contact company to see what they can do about it...

100 rounds, stained BCG, residue does not simply wipe off!!

by -

Product had a great finish. Super smooth and it actually felt like there was already lube on it, but there wasn’t. I ran 100 rounds of Fiocchi through this BCG. Took the BCG home excited to wipe the grime right off. This was not the case. The coating was stained and the carbon did not just wipe off. Especially off of the bolt. I will not buy this product again. Nor can I recommend it. It did run flawlessly for 100 rounds. But cleaning was just the same compared to my other BCG without a Nib coating. Glad I got it on sale. If I would of paid full price for this product, I would definitely be upset.

Fail Zero !

Just received this in the mail today and haven't install it yet but product looks amazing caught it on sale well worth the money. The coating looks good no noticeable markings very clean BCG. Will give updated review once installed and used thanks primary for the quick shipping and great prices my number 1 go to place.

Good but Cheaper on Fail Zero's Site

by

This is an excellent BCG, It recently just reached the 5000 round mark and is still going strong. My only problem with it seems to be the price it is listed at, on Fail Zero's website it is actually cheaper by about 20 dollars, still a good BCG with out spending over 200 bucks.

Love this BCG

by

Excellent product and finish.. So easy to clean and functions flawlessly so far. Always love doing business with Primary Arms. Truly a 5 star company.

Excellent BCG!

by

Had this in my rifle for about a month now absolutely love it! Great looking and great finish! Very easy to clean also. Primary Arms had it shipped the day after i ordered it. Truly a 5 star company. I love that they take the time to talk with you and answer all questions without seeming like they are trying to hurry and get off the phone.

Great BCG

by

Upon inspection I was very impressed. My company owns a metal fabrication shop which produces products for the wireless communications market so I have an in-depth knowledge of quality fabrication. There were almost no tooling marks with the exception of just a few on the bolt lugs but the rest of the BCG was perfect. Very nice NiB finish making for a super smooth surface. Cycled flawlessly in my AR and as a result I ordered one for my wife's AR. Primary Arms delivered fast.

Will buy another

by

Great BCG zero malfunctions just like the name in an AR that had been giving me problems in the past. will definitely buy another one for my current build

Great Product

Able to shoot without any problems. Runs flawlessly. Pleasure ordering from Primary Arms.

great company/top notch bcg

by

Primary arms had a great deal on the fail zero. Customer service was very friendly and helpful. Shipped really fast. Shot 200 rounds through my ar with very little clp on it and never missed a beat.

So nice that I will be buying another one.

Fail Zero BCG

by

Used this on my first AR build. I only have a few hundred rounds through but no malfunctions this far. When I remove the BCG the residu wipes off without even trying. Fit and Finnish is perfect. I know they claim you can run it dry or with minimal lube but I still run mine pretty wet, at least while its new. Primary Arms is great to order from.

Excellent product

by

I bought this product and it's worth spending on.

I honestly have no idea

by

To be honest I have no idea if this bolt carrier group is any good. I haven't use it yet since I don't have enough parts to make a complete rifle yet. That being said, the item did arrive quickly. So that's nice.

A little uglier...

by

This is my second FZ BCG, first one being right before the panic, FA with the hammer. Both of them seem very nicely built, proper staking on the key, and my first one has dealt with some over pressure situations without a hiccup. This one I just got is just a bit uglier though as far as the coating goes. Seems a bit duller, a bit rougher. It lives in an integral 300blk, so it'll always be filthy, just hope down the road it cleans up as easy (paper towel and oil) as the first one. I'd still get another.

Looks Great

by

Haven't had a chance to try it out in a gun yet, but it looks great!

Great deal

by

Got this cuz it was on sale for 99$, ran it a couple times so far with no jams, nice lookin finish for rifle

Fail Zero BCG (no hammer)

by

Works fine. Super easy to clean. The great part was the sale price and the reliability of Primary Arms.

fail zero bolt group

by

Timing was everything. I was looking for a coated bolt group for one of my 3 gun rifles and was concerned that I wouldn't be able to buy the bolt I needed because I expected it to be to pricey. I check out Primary Arms and there it was on sale a Fail Zero. Got it last week and have run between 276-340-682100pm to 358-291000pm rounds with no problems. Will wait a while before I clean it, to see if its easy like I am expecting.

perfect

by

this is my second FZ BCG... the M16FA version is super easy to clean, feels slicker than my WMD so when i saw they were on sale i grabbed 2....

These BCG's are the beez neez

by

This BCG is the sh*# it will make you shoot faster, straighter and girls will want to drop there panties because you have one. So pull that trigger.
