Yes it is and so is stamp collecting. I just sent out my form 1 for my third SBR AR in less then a year building them is fun.Welcome to the club. I built my first one last year then my son had to have one so we built him one. Then I had 3 more stripped lowers sitting in the safe. Now I have a 9" 300blk barrel on order and an dropping of a lower to get engraved next week for my first sbr. Its addictive tto say the least.
and Info!
Everyone needs one!
Unfortunately right now it will cost you a pretty penny to warm up the bore, even more to get it really hot.
Congrats. How about some pics?
