Custom Barrel Work

Seminole offers a full gunshop for all your gunsmithing needs. Whether you are the avid hunter or competitive target shooter, Seminole has the expertise and the in-house capabilities to take your shotgun and give you the highest level of performance.

This procedure actually enlarges the bore of your shotgun barrel. It not only decreases the weight of your barrel, it also disperses the dense core of the pattern into its edges ... giving your shot an even distribution with less pellet deformation. · We backbore from start to finish with a honing machine to ensure concentricity and add a mirror finish.

This procedure allows the wad column to move down the barrel unrestricted, thereby decreasing chamber pressure, felt recoil and pellet damage while improving pattern density. It also increases the long-range velocity of your shot. · We ream the forcing cones to a rough condition, then hone them to a mirror finish.

Choke Installation

Update Invector to Invector Plus or Beretta Mobile to SG2 - $75 per barrel plus chokes

Seminole’s custom choke system enables you to switch out chokes to match your hunting or target situation. Our system also updates Beretta’s shorter system choke to our SG2 system specially designed for backbored Berettas. Our SG2 system aids in pellet distribution and pattern performance, as well as certifying the DEAD-ON point of impact, thereby delivering the premium punch from your Seminole Beretta. · Seminole will bore out your fixed choke, then precisely bore and thread your barrel for the appropriate choke system.

No burrs or sharp edges with Seminole porting. Porting also reduces muzzle rise up to 45 percent, thus making your second shot quicker to recover while reducing recoil up to 15 percent. Our porting is designed to compensate for left to right muzzle swing. · Our ports are precision machined and deburred using the latest aerospace technology.

This procedure enlarges the gas port holes in semi auto barrels allowing your gun to function properly when shooting lighter target loads.
