Okay guys been awhile since i've been on here. I have 2 questions for you all, first, what do you prefer the AR platforms or the HK platform. I would like to hear from anyone that may have shot both, does the AR-10s have a lighter kick than a PTR91? How do they compare for accuracy? I have a PTR in .308, I have achieved a 3 shot group with winchester BT 168 grain ammo at 189 yards of .75 inches center to center with a tasco 9-45x56 scope. I am assuming accuracy is similar in ARs. my bigger question is about kick. I also recently put on a magpul stock instead of the sidefolder but have not had a chance to shoot it.... will this stock help with kick? since the gun never felt like it fit right and does now. I also am wondering about the rubber buffer. it has a neck on it that i believe the wider end goes forward toward the barrel. but after buying the rifle i believe it was in backward with the narrow end forward. does anyone know the correct placement? I am getting ready to purchase a new gun for my wife. She has shot my PTR and does not seem to mind the kick at all. she also wants her own rifle. I am just looking for info on whether i should trade my PTR in and get 2 AR10s or keep mine and get 1 more PTR. HURRY BEFORE POTUS wont let me get one!!!!
