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.

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.
