Barrels, Barrels, Barrels!!!
Barrels for Virtually Any Application
Rifle barrels come in many different sizes, shapes, calibers, and configurations.  They are also meant for many different firearms platforms.  At Keystone Accuracy, we do them all, and do them well.  Much of what we do is geared toward rifle competition and police & military applications where accuracy and performance are an absolute must, since there is no such thing as a second chance.

We specialize in rifle barrels for high end bolt actions rifles, the AR-15 platform, and the larger cousin, the AR-10/LR .308 platforms for big game hunting, tactical, and competition applications.  Keystone Accuracy barrels can be found in hard core competition all over the United States, as well as on high end rifles taken to other continents for big game hunting.
NRA/CMP Legal AR-15 Service Rifle Competition Barrels
Each barrel is contoured using the latest CNC technology to guarantee absolute uniformity.  A standard service rifle barrel is 1" under the hand guard using a .750 gas block tenon with a slightly smaller diameter just forward of the gas block in order to allow a front sight or gas block to be installed without scratching or marring the exposed barrel portion.

Once each barrel is contoured, it is indicated in a lathe in order to cut and polish the chamber using either a .223 Wylde, .223 CLE reamer or a customer supplied reamer.  Each barrel is treated with the same painstaking care as a competition bench rest barrel, where absolute accuracy is demanded.  Once the chamber is installed to the minimum side of SAAMI spec, a barrel extension is torqued to proper spec and a gas port is carefully drilled and deburred from the inside of the bore.  If service options are request
ed, they are also completed prior to cutting the 11 degree muzzle crown.

We also offer fully contoured but unchambered, and undrilled blanks since we realize that there are many home gunsmiths in the crowd that prefer to chamber their own barrels.

Muzzle options

All barrels can either be requested in both post-ban and pre-ban configuration.  This "ban" terminology refers to the Clinton gun ban of 1994 which restricted the public purchase of threaded muzzles.  It expired in 2004, however the terms conveniently stuck.
The most common muzzle threads are 1/2-28 and 5/8-24.

Muzzle threads............add $10

Ambidextrous Capability
