The Agency Arms Mid Line barrels for Glock 17 Gen1-4 handguns are built to be durable, accurate, and aesthetically pleasing. The Mid Line series is made from the same 416R stainless steel as the lower models but features machining enhancements like seven straight flutes and a threaded muzzle. This Glock 17 threaded barrel comes with a 1/2x28 thread protector that you can use until you get a 417 compensator or decide to suppress it. The 1:10 twist goes through a process called pulled broaching to ensure the lands and grooves are extremely consistent, resulting in greater accuracy. The Agency Arms Mid Line G17 barrels come in three different finishes and this specific model comes with the DLC (diamond-like carbon) that is extremely durable. The Agency Arms Glock 17 fluted threaded barrel is an easy drop in upgrade that will improve function while giving your handgun a unique look.

Great threaded barrel

by -

I considered many barrels and decided on one this for my 17.4 and could not be happier. It has the faster 1/10 twist vs 1/12 or 1/16 like some others so it will have no trouble stabilizing the heavy, slow rounds I plan to shoot out of it. Also, it has what I believe to be the ideal amount of exposed barrel before the threading begins, some have almost none, some have what looks to be 3/8”. I think this barrel will give compatibility with any device that would be used, without being ridiculous. I ran 200 rounds of mixed ammo through it with zero malfunctions, all other internals are stock. This barrel shot groups as well as my much more expensive 2011, if I buy any more threaded barrels they will be these. Another flawless transaction with Primary Arms!
