I'm wanting to buy a "blue gun", rifle, for training. I have several "handguns". Cheapest full size "blue gun" rifle I have found is over $150! That seems stupid expensive to me. I can buy REAL guns for that kind of money. What I may end up doing is putting together an AR out of out of spec parts, shot out barrel and I bet I can do it for less than that.....Thoughts or leads appreciated!
