Need some help getting my first three gun setup.

Hey everyone,

ive been stalking the forums here for a little while and this is the first year im really looking at getting into 3 gun. i have shot a few before with borrowed gear and i have limited amount of money (really only 6 or 700) to finish my gun setup. I right now have a glock 17 all stock which ill be using for my pistol, a 16 inch colt target AR 1/7 twist a2, and no shotgun. so my question is this for my shotgun i was looking at picking up a Mossberg 930 combo field secirity, in the comps i have shot i used an 870 and the pumping action is by far my biggest slow down. next right now i have an a2 AR with a red star 3x handle mounted scope and after the shotgun purchase i have about 2-300 left to spend. should i buy a stripped colt flattop upper and move barrel etc over to it, buy a new complete upper from any company and mate it to the colt lower, or just use my a2 upper with the scope mounted way up on the handle and spend the rest of my money on ammo for practice? if i buy a new upper ill have to shoot the first few matches with irons (i have never competed with a scope so its not a big change to what ive been doing).

thanks for advice in advance and sorry if i made this confusing.

A flattop would offer you the best choices in the long run, but personally, I'd take the scope off your current AR, get the 930, and spend the other 2-300 on ammo and match fees. Spend some time with the more experienced shooters and see what they are running. Find your weaknesses gear-wise, and work to correct those over the long haul. I know for me, when I first got started, it was not my gear that hindered me from progressing.
