HELLO, I'VE BEEN BUILDING AN AR-15 & I NEED HELP ATTACHING THE BARREL SINCE I DON'T HAVE THE TOOLS & ONLY PLAN TO BUILD THIS ONE; OOOHH...I'M SORRY BUT, YOU SEE THIS PISTOL? IT WOULD BE IN MY MOUTH & MY BRAINS WOULD BE ALL OVER IF I DID THIS CAUSE THE GOV CONSIDERS THIS MANUFACTURING & I'M NOT GOING BACK TO PRISON; MY GOV WANTS IT'S PEOPLE TO BE HIGHLY KNOWLEDGEABLE OF THE HIGHEST DISTRIBUTED & AVAILABLE SEMI AUTO RIFLE...WHY?
