Send us your barrel and we can perform the Vang Comp System modifications and then send it back to you. Our patented barrel modification process is comprised of 3 machine operations (Lengthen forcing cone, Backbore, and Ports) that combine to offer reduced recoil, reduced muzzle rise and tighter shot patterns. **We do not currently work on Benelli’s, Beretta’s, shotguns with chrome-lined bores, or older shotguns that are marked 2 3/4″ only.** We STRONGLY recommend choosing the “WITHOUT PORTS” option if you are sending a semi-auto barrel FLIGHTCONTROL OPTIMIZED – we only recommend the for people who ONLY shoot Flitecontrol ammo. It’s comprised of Lengthened forcing cone, SLIGHT backbore, VCS Ports. Look at this mod as sort of a barrel accurizing service. *The Vang Comp guarantee of 10-12″ patterns at 25 yards with good quality buckshot is not a guarantee with this service. Vang Comp does not take credit or blame for the buckshot patterns through this bore. This was designed specifically for a Law Enforcement agency that was ONLY ever going to shoot FliteControl ammo and still wanted our Recoil Reduction, Muzzle Flip Reduction, Muzzle Flash Reduction, and better grouping with slugs and less-lethal. The current turnaround time for barrel work is between 30 and 60 business days.
