AR-15 9MM BOLT ASSEMBLY FOR GLOCK Reviews & Ratings

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.

Perfect
After around 6000 rnds my PSA AR9 broke an extractor while firing 9mm +p 124 gr. HP. I was unable to locate an extractor at the time other than one for around 80$ Brownells had their BCG for $99 dollars so for $20 more I got a new BCG and when I installed and tested the Firearm, I fired 200 rnds of steel, brass and defensive rounds. no issue. I have subsequently put another 300 rnds thru her with 0 malfunctions thus far. It should be noted that in the entire time I owned the gun it never malfunctioned till I broke the extractor. Now extractors are available at normal prices so I'll replace the old one and have a backup BCG.

Read the reviews...
With the bolt body being .969, there's not much clearance between the bolt and the receiver/buffer tube, any "hiccup" will cause a malfunction no matter how much you grease the bolt. Luckily, Brownell's has a great return policy...

Wont Function
Absolutely will not function in any of my AR 9mm builds. Bought for an Aero Precision EPC build but also will not function in my Quarter Circle or Rock River builds. Seems to be oversized will not retract into buffer tube and upper and lower receiver fit is really tight when installed. Returned and purchased a different bolt.

Disappointed.
Bolt body is .969 and Mill spec is .930. Very tight fit into the buffer tube and would hang out of battery when slowly closing the bolt. I feared using this bolt would damage the buffer tube and possibly the upper. This is the first time I have been disappointed with a Brownells named product. Returning for refund and purchasing an Angstadt Arms bolt.

Doesn't work with EndoMags. Don't try!
I'm sure it's a fine product for Glock mags, but the tolerances don't work with EndoMags. It totally destroyed an EndoMag insert and the Pmag it was in. Won't cycle. Bolt won't close all the way with a P-mag that has no guts - just an empty shell. Now I need to spend $50 to replace my destroyed EndoMag and P-mag plus return this BCG and order something else.
