Tokarev SVT40

[Low & Slow]

If some rough dimensions will do you any good, my six port has an OD of .746". the OAL of the wide part comes to about 1.922" if you don't count the .064" flange of the cap at the muzzle end, and the taper where the barrel flares to meet the increased diameter of the brake. The flare begins at about .421" forward of the front sight base. Reduced diameter section of the cap ahead of the flange is .352" long, and about .549" in diameter, not considering the flats for unscrewing it. ID of the muzzle end of the cap comes at .353". Distance from the front of the front sight base to end of muzzle cap is about 2.794". This may not add up perfectly, but I'm just working with the old calipers after a beer or two. Hope this can get you ballpark.
