Quickly & Easily Drill Recoil-Reducing Ports In Any Shotgun
Accurately drill recoil reducing barrel parts in the shop or on the range with only a hand drill. Universal clamping fixture adjusts to fit any barrel style, for accurate barrel porting. Two jigs allow drilling different size ports depending upon the user’s preferences. Larger ports give more effective recoil reduction, however, smaller ports are aesthetically more pleasing. Each jig uses a removable bushing: Jig #1 has 35 bushing holes per side and uses a #40 drill bit; Jig #2 has 23 bushing holes per side and uses a #31 drill bit. The versatility of the jig permits you to lay out a variety of porting patterns.
