Colt M16/AR15 Bolt Assembly

Not marked MPC, marked MP. I was able to return it and had to pay a restocking fee. It would be nice in the description, I was told it is new colt markings, the picture is traditional Colt markings, I would not have ordered it in the first place. Fast refund, though.

It mated as it should with the Colt carrier and runs to spec. Tight fit with excellent tolerances

Awesome as always a great experience with Arms Unlimited. MP marked Colt Bolt how can you go wrong? Great prices and awesome hard to find parts. Super fast shipping and the best customer service in the industry!

works outstanding well with KAC sand cutter bolt carrier

I got this bolt in, and it doesn’t have the characteristic white dot, and the extractor is NOT made by Colt. Pretty sure it’s FN. Is the bolt made by Colt? Could be, it’s MPT stamped, but it could be a GI bolt that I overpaid for too. Also wasn’t impressed by the way it was shoved in a bag with other parts and then mailed so the parts rubbed against each other. For this price, I expected better.

I called in and spoke with a woman in customer service about a bolt assembly. She went above and beyond what you would expect anyone to do in order to help me get exactly what I was looking for. That kind of service has earned them a new loyal customer.

I recently had to replace the Bolt on my Bushmaster AR-15, I decided on using the Colt due to there standards and reputation. I was very pleased with the Bolt I received, it went right into my CGA, I have put about 300 rounds through it and it has worked flawlessly. Product shipped out on a timely manner I will defiantly use this site again.

Seems they mail parts out of a bulk bag or box, my new bolt has a bright sharp feeling nick top middle corner of extractor, and few other slight finish bruises. Just as when i was in the Army. Spare parts, and that is all they are. Order was placed over the weekend, package hit the mail Tues 1st class, and made the transcontinental trip to the SEUS Gulf Coast by Thurs. Zero complaint, genuine article, and will definitely be placing another order quite soon...QUITE soon....only making my shopping list of OEM goodies for my Colt.

I ordered a colt M16/M4 bolt and a colt USGI 30 round magazine. Both products were shipped promptly and were exactly what I ordered. Finding Colt parts can be difficult and finding them in stock even more so. Colt parts are preferred by most as they are known for their quality. If they are good enough for our military then they are good enough for me.
