The gas key is properly staked, the extractor spring has been upgraded with an O-ring for increased tension, and all surfaces are MIL-SPEC heavy phosphate coated or internally chrome lined. The Spike's Tactical Spider Logo is engraved on the right side of the carrier to show through the ejection port. Assembled BCG weighs 11.6 oz.

Spikes Bolt Carrier Group

Bolt works great. high quality material.

good for carbine , needs tweak for pistol

by

comes with standard extractor spring (4 coil) and standard o-ring. that would work fine in a carbine or rifle, but for pistol with short barrel (7.5") i was getting failure to extract, so i had to upgrade the extractor spring to a 5 coil spring to fix the issue.

Great service as always

by

Delivered fast, product is what you would expect from Spikes. 100 rounds in and no issues.

Got this on the cyber Monday sale what can you say the price was great. The machining and finish on this thing is very impressive. I have two M4 clones and will use this for a back-up or for my next build.

Great experience with Primary Arms. I bought this part along with many others to complete my first build and it all went together easily. I have about 300 rounds through the rifle already with no issues. Will definitely buy from them again.

Great quality, as expected from spikes. Also, Primary Arms has the cheapest price on the whole internet for this BCG that I could find. And fast shipping.

Great Prices, Better Service

Great speed, friendly customer service over the phone, and a low cost. Bought a barrel and hand guard to complete the build just a couple of weeks later. Will definitely buy from Primary Arms again.

Spikes, Awesome Bolt Carrier!

I am very pleased with this BCG. It is heavy duty and the finish is clean. And once again, I am very happy with Primary Arms fast shipping. I order from many web based Firearms businesses and no one compares with them. I ordered my BCG in the morning and two hours later, I am notified they have shipped the order. And I paid for the most inexpensive delivery method.

Great service & great product all at a great price

by

I bought the Spikes Tactical BCG for a rifle I am currently putting together. I cannot offer a review on the product at this time but I can certainly offer my opinion on the service and price. In a word....great! I look forward to doing more business w/ Primary Arms in the near future.
