Ratings & Reviews
I also received a bcg that was not properly stake it looks like it was barely tapped I contacted spikes a while ago and never got a reply back. I think I'll try a chrome one from rainier or phosphate from bcm
I had the exact same problem as others have reviewed. After about 20 rounds the BCG would not cycle the next round. I took out the BCG to find that the gas key was loose. It was not properly staked. Do not buy this BCG.
Not worth it...
The gas key was not properly staked (looked like they barely tapped it on one side of both screws which btw are cheap imported fasteners that are known to have issues! I thought Spikes bcg's were of better quality than this but I guess I was wrong!
Revised for - DID NOT CYCLE
Hello everyone recently I wrote a review for this bolt because I received a bad one and it would not cycle and broke pieces of my AR15. Today I write a review revitalizing that one and letting you all know that I got a good one it functions and works fantastically! The one I received was really clean and looked great I function tested it with snap caps prior to going to the range and all was well. Went to the range and fired 1 shot reloaded then 2 reloaded then 3 reloaded etc. Everything went through flawlessly as well as a rapid fire test. Took the bolt out after shooting and all was well cleaned it back up oiled it up and it was good as new. This bolt is a great buy assuming you get one that works going to give it 4 stars because it came pretty and this one worked only 4 not 5 because my first one did not function. Good Job Spikes Tactical!
Did not Cycle
I took my newly built rifle (First build I have done) to get safety checked by a Gun Smith since I have never built a rifle before. They were going through the safety check and everything checked out they said rifle was built perfectly and everything was great also passed the head space test (Go/No Go). Went to do the Test Fire (the final test) and after 3 shots the bolt would not cycle it seized. They took it apart and there was metal shavings and my buffer tube was destroyed. They got a new buffer tube and took the rifle apart and cleaned/re-oiled everything then put it back together. Tried to fire again and the BCG would not cycle again they changed out the BCG with a different one they had on hand (Stag) and it worked perfectly fine and passed all the tests. Pretty sure this was due to mass production however I am upset that I am out of 200 bucks because it was not properly inspected and was not in spec. Will purchase a different BCG in the mean time I have a Stag standard BCG in my rifle. Only thing this bolt had going for it was it looked pretty....
Have had this BCG for some time. NiB will discolor over time totally normal still slick as hell. mine is a burnt brownish yellow chrome color and still functions well. if people are buying this expecting not to clean it you're dreaming.
Primary Arms Shopping Experience
Primary Arms is absolutely a top notch company and a joy to shop at. Thanks for being a class act..
Not as good as my WMD BCG.
Thanks to Primary Arms for their fast shipping and great customer service. I own a WMD NB BCG as well and it cost the same as this Spikes BCG. The machining and tooling is better on the WMD. I would buy the WMD instead next time. It looks as though the firing pin, gas key bolts, gas rings, firing pin retaining pin, ejector and extractor pin are not coated in nickel boron on the Spikes BCG. Everything on the WMD BCG with the exception of the springs and gas rings is treated with nickel boron. The attention to detail is lacking. The finish on the gas key is rough and the tooling and machining isn't anything special. I was expecting a higher quality BCG for $180.00. This will be my last from Spikes. UPDATE: After shooting around 1,300 round of .223/5.56 the bolt is completely black and I can't get it to return to it's silver like original condition. My WMD bolt cleans up just like new every time. I hope this helps someone who is spending their hard earned money on a new NB BCG.

Fast shipping great website
Super fast shipping TOP NOTCH service!
Excellent service. Fast and problem free.
The spikes tactical bcg that I had received had a very obvious flaw in the finish of the nickel boron on the rear of the bcg. The finish was very rough dark tan in color almost like rust. Returned it to PA with prepaid shipping label and they are suppose to send me another one. That was almost two weeks ago and still haven't received the new bcg that I was suppose to get a week ago. PA is still being very nice and easy to work with throughout this process but I just want my bcg.

This thing is as smooth as a baby's butt. And the spider logo on it adds some cool factor to it. Don't bother with the lightweight version that spikes offers as it is BARELY lighter than this one. Pretty dumb actually. Buy this one. You will love it.
Happy happy happy

Not as easy to clean as I was hoping for
by Matt S
Used this BCG for the first time this past weekend. Shot 120 rounds and although it shot just fine I could not tell any difference in performance or ease of cleaning between it and my stock Daniel Defense BCG. Kind of disappointing for the $$ I spent....There is nothing functionally wrong with this BCG but I'm giving it two stars because IMO the nickel-boron coating seems to be a bit of snake oil.
