TN.Frank - How did your buffer material work out? Any suggestions as to where I can get some? New to HK & love my HK4. When I got it the seller says he didn't even know it didn't have one. Bought one and made a plate before I ever tried to shoot it. Plate broke - was not steel. Going to try again with smthg thicker and steel. Any helpful info? Is plate same shape as buffer? Please advise. Thanks. Patient & Persistent.
