I have a Suppressed Weapon Systems MISB integrally Suppressed 300 Win Mag barrel for the Desert Tech SRS platform. The barrel is 32" long, with a 24" barrel and 8" suppressor section. It was fitted and chambered by Short Action Customs from a Bartlein blank. The barrel has been cryotreated and has the barrel extension included. It is VERY quiet with both supersonic and subsonic loads. I have put less than 150 rounds down it. Asking $2200, and all NFA rules apply. It shoots 168 Bergers 0.75 MOA, and is the quietest suppressor that I own. Easily pushes 168's past 3000 fps. Only reason I'm selling it is my current barrel with direct thread suppressor is a 0.2 MOA combo. All NFA Rules apply upon purchase.
