LR-308 Rifle Kit (18” Parkerized Barrel & 15” M-Lok Handguard) w/ Premium Magpul Accessories & 80% Lower (1:10 Twist)



We asked if you were serious about upping your .308 game with one of our new LR-308 build kits. What if we sweetened the deal? What if we provided you the means to do so but added in some premium Magpul parts? Do we have your attention? Good. This kit’s upper assembly affords you a 18″ mid-weight SOCOM-profiled barrel to better handle a higher number of rounds put downrange. It also comes with a 15″ M-Lok handguard for mounting a bipod, foregrip, or whatever else. We also swapped out some of the standard parts for Magpul ones. You get an MOE grip and trigger guard, and a Magpul stock. So grab some backup sights and some mags and ammo, and get out there and start slinging some lead.
