Update on the old M-1. No bent barrel according to the bore gage! I bedded the action in a beech stock i picked up at a gun show 10-12 years ago, trimmmed the rear handgard so theres no contact with the stock, reciever or barrel except at the ring and band. Dressed the crown, and added a thin o-ring between the upper handgard and gas cylinder so the two won't slam against one another during recoil. Heres an 8 shot group at 100yds after the mods. Ammo used was handloads with 168gr Hornady OTM's and IMR 4064 powder.
