whats up felllas, I recently bought another WASR 10, about 6 years old, It has the normal slant muzzle break but it has right handed threads. I have a WASR 10/63 that has the normal ak left hand threads and can't find much info on why this one has right hand threads.... also after about 2 shots the trigger pivot pin comes loose and backs out the left side causing the end to slide back in the receiver. Ive tried hamming the pin back in real snug but it just backs back out. I bought the Tapco G2 single hook trigger to help out. any way i could flare the end so it can't back out? thanks for any advice guys.
