Already have a great shooting firearm? Gunwerks will provide new 30mm rings and a 5-20 LR Huskemaw Rifle Scope. You provide your firearm and 40 rounds of your factory ammunition, Gunwerks will calibrate a custom drop turret that matches your exact ballistic profile. You will be able to range and dial just like the Gunwerks LR-1000 and LR-800 models. To increase your terminal performance, try ammo loaded with the Berger VLD Bullet. We recommend a rifle and ammunition combination that shoots at least 1-1/2", 5-shot groups. The Gunwerks handloaded ammunition has consistently shot sub MOA groups in factory rifles.
