Colt M16/M4/AR15 Bolt Gas Rings | Set of 3

Fast free shipping and it was at a good price just what I was looking for

These measured identically to an original from an unfired bolt. They have fired about 400 rounds since install and the writing of this review

Ive done other reviews and as ive stated in them i only use Colt official parts on my Colt M4. Colt just has a quality above the rest! Some people claim you are paying for the name and that maybe somewhat true, but when you do NOT batch test and you test every firearm that goes out the door...its hard to debate the subject further! Just like their firearms, their replacement parts are top notch! That rule of thumb has kept everything working at peak performance! Im not talking about upgraded triggers, but high stress items like on the BCG on my M4...i.e.,gas rings, firing pin retaining pin, extractor spring assembly, n etc. i am very happy with these gas rings and will be buying another pack for my parts kit. Cant have too many BCG replacement parts! Thank you for selling quality AU! Cav, Hooah! Scouts Out!

Legit Colt gas rings at a great shipped price!

And at good price and free shipping. My only worry is when word gets out, no more parts for ME.

Great Customer service and prices

The rings fit and function great...

Genuine Colt parts can be hard to find...AU is a great source for those hard to find small parts.
