What is the BROWNELLS - BRN AR-15 Glock Pattern 9mm Luger Bolt Assembly, Nitride?

AR-15 9MM BOLT ASSEMBLY FOR GLOCK MAGAZINES

This Brownells AR-15 9mm Bolt Assembly is a no nonsense, go-to option for those building up a 9mm AR.

As this platform becomes increasingly popular, we wanted to make sure we offered a highly reliable option at a good price, and this 9mm Bolt Assembly is just that part.

This designed for lower receivers that feed from Glock® pattern magazines.

The bolt, gas key and carrier weight plug are all made from 4140 steel, while the extractor is made from 4340. It is finished with a durable Nitride finish.

And the carrier weight plug is easily removed for use with a Law Tactical Folding Adapter.

Due to the tolerances of this 9mm Bolt Assembly it is not compatible with the Mean Arms ENDO Mag conversion kit.

Good Bolt
I'm not sure why it doesn't work with the Endomags but it does work with the newer Exomags no problem. I wasnt aware of the compatibility issues at first and was neverous but everything worked out!

Great drop-in replacement
I needed a replacement bolt for my PSA AR9 and this 9mm bolt assembly for Glock magazines was a perfect drop-in fit. Installation was straightforward and it ran flawlessly right out of the gate with a healthy dose of oil. Cycling and feeding have been 100% reliable so far, and it brought the rifle right back to life. Excellent option if you’re looking to replace a broken AR9 bolt without any headaches. Would definitely recommend.

Bargain
I found nothing wrong with the design or function of this bolt. My rifle goes bang each time the trigger is pulled. You cant find a 9mm bolt for this price anywhere, especially during the current state of the union we find our selves in.

Great 9MM Glock AR Bolt
This BCG is needed to use 9MM Glock magazines in an AR platform. The Colt pattern 9MM BCG will not work with Glock 9MM Magazines because of the narrow feed lips. I have fired over 1,000 rounds using my stock Glock 17 magazines with no problems, Anyone wanting to build or use an AR lower made for 9MM Glock Magazines this is a must have part. Thank you Brownell's for having what I needed.

Great quality and value
This bolt carrier group is well made and has good fit and finish. It will work with a standard milspec trigger and hammer group as well as enhanced trigger groups.
