Luth-AR 22LR Bull Barrel 18" 1:16 Twist 416 SST Threaded - Fits Ruger 10/22

The Luth-AR 22LR Bull Barrel is a heavy-profile 18" replacement barrel engineered for Ruger 10/22 style rimfire actions and other compatible semi-auto .22 LR platforms. Machined from 416 stainless steel and finished with a blasted matte surface, this bull barrel delivers the rigidity and heat dissipation that the factory 10/22 barrel leaves on the table, making it a natural fit for varmint, plinking, and small-game rigs built on the 10/22 chassis.

Luth-AR specs this barrel with a 1:16 rate of twist - the standard rimfire twist that stabilizes 40-grain .22 LR cartridges - and cuts the muzzle with 1/2x28 threads so you can mount a compensator, muzzle brake, or thread protector of your choice. The heavy bull profile adds mass to the front of the rifle for reduced recoil and improved harmonics, pairing naturally with the Luth-AR MCA-22 chassis system or any standard 10/22 receiver.

This is a drop-in barrel only - no action, receiver, or magazine is included. The 22LR-BLB1816 is a straightforward performance upgrade for any 10/22 builder looking to swap the stock sporter barrel for a heavier, threaded stainless profile.
