I have a Tippmann A-5 basic. I haven't added or done anything to it. I do tend to play the sniper a lot. I find a spot and lay down and wait 45 min+ or however long it takes to get a shot. My friend has a 18 inch RAP4 Tactical Rifled barrel that he is selling for $20. Said it doesn't fit his style. Should I get it? Would it benefit me? He has only used it 3 times and said he paid $45 brand new. Should I get it?
