Had Brannen Moss of Moss Firearms in Jasper do the work for me. Turns out that the inside diameter of the jungle flash hider copy from Numrich is .671", and the outside diameter of the Mosin barrel is approximately .670" somewhere around 16 or 17 inches. (for all ye graduates of hi schoo)...
this is one of mine, had the 9130 barrel cut to approx. 16 1/2 inches, and installed a jungle carbine type flash hider...
the flash hider does it's job, and i haven't shot the rifle for accuracy, i have only popped 2 liter soda bottles in the air with it at one hundred yards....
great solid handguards....i paid near 4 for mine a few years ago....i have a buddy with three new in box sets at 250 each..... anyone interested just pm me for name and number and such..... i truly love mine...
awsome looking rifle....!!
