Quality GLOCK® parts for factory pistols and G80 builds.
Like the popular AR-type rifle, the GLOCK® handgun is loved for its massive market of aftermarket and custom parts. At 80% Lowers, we’re happy to provide a catalogue of American-made, custom GLOCK® barrels, slides, and individual slide and frame parts to complete or upgrade your favorite striker-fired handgun.
G80 & P80 Frame Parts
Starting your first build? Check out the G80. Need all the other parts to finish your pistol? You’re still in the right place! We have lower and upper parts kits, barrels, slides and more for GLOCK’s most popular handgun series, including the G17, G19 and G43.
Drop-in GLOCK® Barrels and Slides
You built or bought a GLOCK, and now you wanna make it better. Easy. Check out some of our match-grade barrels, like this target-crowned GLOCK 17 barrel. It fits factory Gen 3 G17 slides.
Optic-Cut GLOCK® Slides
Few upgrades are better than a micro red dot, but you need the right optic-cut slide. We’ve got you covered with quality slides from LFA. Their Elite G17 slide is pre-machined for an aftermarket reflex sight, like the popular Trijicon RMR. With weight-reducing vents and a tough Cerakote finish, an upgraded slide like the LFA Series sets your GLOCK®, G80 or P80 pistol apart from the rest.
