This is my go to BCG

by -

You really can't go wrong with Spike's. I installed this BCG in a PSA build of mine and I'm very satisfied. Runs flawlessly and is made of the highest quality. I put at least 500 rounds through this no issues or hiccups. I'll be buying another.

Spikes phosphate BCG

Firstly, Primary Arms,,, 5 Stars for you folks. Outstanding selection, prices and ship times. You can slide on some parts but certain parts of the AR need to be of good quality, BCG being one of these. The BCG inspection, well made, key staked properly, finished nicely, most importantly "PROPERLY" chrome lined for bolt. Absolutely on par with BCM. Thanks again Primary arms--may you live forever.

High Quality BCG with the COOLEST LOGO!

by

Exact machining, perfect fit, flawless operation and the coolest logo imaginable. I've put ~1000 rounds through so far and this BCG functions flawlessly. I'm about to buy my 2nd BCG and I'm not even looking at anything else.

My go to BCG

by -

Just purchased my 3rd one of these. You'll be hard pressed to find a better BCG in the prince range. This will be my go to BCG from now on. No need to shop around anymore.

Best Dollar for Dollar

by -

I've purchased two of these as of today August 28th 2018. I got the second one because the first one has worked flawlessly. I put it in a Spike's Tactical custom build for my wife in 300 AAC Blackout. We've put a couple hundred rounds trough it. No FTE, FTF, or malfunctions whatsoever. High quality, good price, made in USA.

Quality and Performance

by -

What can I say. It is Spike's and it simply works. No head space issues, no staking issues. It has cycled every round I've thrown at it without fail.

The best

by

In the past, I have always used the BCM Gunfighter BCGs. I decided to try the Spikes Tactical after reading some very good review and I was not disappointed. Everything is as it should be. Very nice fit and finish.
<br>Great product, fast shipping and great price.
<br>Primary Arms and Spikes Tactical are the best.

Gas key not staked

by -

I’ve never used any spikes products, but have always heard and read good things about their products. Staking the gas key is being done by even the cheapest manufacturers now, and isn’t something that I would expect spikes to overlook. It makes me question the overall quality of the bcg. Spend the extra money and get a BCM.
<br>
<br>From PA: That is not normal. Please get in touch with us so we can get you swapped out with a properly staked BCG.

Good Stuff!

by -

Works as expected and if it didn't, Spikes would make it right. I prefer Spikes Tactical due to their quality but their customer service is outstanding as well.

Primary arms is just awesome!

by

I love primary arms, best delivery times. Order one day get the next. Wow. This BCG looks great and is smooth. No worries. It functions perfect, thank you.

Can't beat this BCG

by

Haven't seen a recent review on this so i thought I'd put up my own. I gotta say, this is an awesome BCG! Works flawlessly with the ammo I've used, i mostly shoot Federal 55 gr and X-TAC 62 gr. Utilizing an AR Stoner barrel and Core15 upper, this BCG run perfectly. So far, about 400 rds down range, and this Spikes BCG has not failed me yet. The only thing is when you first get it the ejector pin is very stiff and needs a little break-in but other than that its G2G. Like it so much, my 2nd one is already in the mail for my next build.

Trouble

by

Bought this BCG after reading the large number of positive reviews hoping to get an awesome BCG that would withstand the test of time. Well it lasted alright 2 rounds. The very first round cycled just fine but after being fired and ejecting the problems began occurring. The spent casing ejected and as the bolt picked up the next round out of the magazine the seat of the round appeared to fail to seat properly in the bolt and the round only made it about halfway into the chamber before jamming. This continued until I thought I saw what the problem was. I could see that the bolt wasn't picking up the round correctly as the lip of the case was partially sitting off to the side of the ejector. I used my pocket knife to hit the round over more in line with the chamber. As I did this the bolt was then successfully able to seat the round in the chamber. However this problem persisted with an entire 20 rounds loaded into a standard Magpul Pmag. Believing the problem to strictly be the BCG and nothing more I swapped the Spikes Tactical with a Bear Creek BCG that I had in a separate upper. Low and behold no more problems. The gun cycled flawless through many more mags. I will be contacting Primary Arms and asking for a refund as this is unacceptable. This was a brand new out of the box BCG that just flat out had issues. The Bear Creek was new as well so this had nothing to do with a ''break-in'' period. This was an every round issue aside from when I would manually pull back the charging handle and send it home. I'd read in a separate review on Brownell's that Spikes had possibly stopped building their BCGs in the USA so this may be the issue. I've always heard good things about Spikes Tactical so I'm hoping that I just happened to get a lemon and that this is not a continuous problem that others are seeing. FYI for informational purposes the rifle I was using was an Anderson Arms lower with a BCM parts kit carbine buffer tube and an Anderson Arms upper receiver with a mid length gas system. Ammunition was American Eagle 55 grain FMJ.

Missing Ejector Pin

by

Mine came missing the ejector pin spring o-ring and roll pin. Left customer service a voicemail this morning - will report back. Probably a one off odd deal...

Great BCG

by

Top notch product in my opinion. Functions great. Looks awesome. Will be my go-to on my next build.

Good BCG

by

Spikes Tactical comes through for me . I bought this BCG for my DPMS ORICAL because the original one was not mil spec. I also installed an a H1 buffer . I went to the rang over the weekend and she functioned flawlessly . I fired about 200 rounds of assorted ammo . I shot Wolf tula American eagle Perfecta 62 grain 5.56 NATO tracer rounds and 62 grain 5.56 penatrator rounds. I used Weapon Shield gun oil in and on the Bolt and carrier . I did clean and work the bolt in and out of the carrier a few time as it was pretty stiff on arrival . After I cleaned and worked the bolt I could flic it out . One thing I had to do was center up the roll pin for the ejector was sticking out ever so slightly. I am very happy with this BCG and highly recommend it !! BTW my DPMS is driving tacks !
