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.

Great.

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

by

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!

by

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.

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.

Spike's Bolt carrier group.

by

I like Spikes products. This bolt carrier is of excellent quality and performance. I haven't had any problems with it and don't expect to. I run about 100 rounds through it and not a bit of trouble. I cleaned the weapon and it will probably be a closet queen now. It was just the fun of building my first AR.

Spikes does it again!

Installed this bcg In my Stag Arms upper and it worked flawlessly! Nice smooth action and the cool spider logo doesn't hurt either! Highly recommended!

Perfect

by

It's a spike's product, and they only put out quality components. I wouldn't hesitate buying anything from spike's. So far, it just as good as my BCM bcg at a slightly lower price.
