LanTac Threaded Fluted Barrel for Glock 17

Upgrade your Glock 17 with LanTac’s threaded, fluted match barrel. Precision machined from premium 416R stainless steel with DFARS compliance.

LanTac’s proprietary fluting pattern reduces weight while increasing barrel rigidity and heat dissipation. The 6-groove, 1:10 twist rate is cut-rifled and then double-honed to a smooth 12 RA bore finish. The match-grade chamber features a polished 16 RA finish.

The 1/2-28 threads allow fitting most 9mm pistol suppressors or other muzzle devices. A thread protector is included. This is a drop-in replacement for Glock 17 factory barrels requiring no gunsmithing.
