Ok what are the chances out of 1 in 10 that if I buy a barrel off of the classifed adds here that it fits my receiver. Mine was made in 94. ( I only have one receiver) I am one of those guys that can build you a house from the ground up but don't ask me to work on your car. I can take things apart just fine but when I try to put them back together I most times have left over parts that I figure were not needed in the first place. Is really realistic that I can fit a barrel myself from the info. that I can get from here?
