I already have two Colt ARs, a twenty inch barrel and a sixteen inch carbine. I originally wanted to SBR an AR, but I came to the conclusion that one of the XM clones with the 11.5" barrel with the 5.5" flash suppressor is almost as short, only about 3 inches longer than an 11.5 inch barrel with the A2 flash suppressor and I can save the $200.00 transfer and the B.S. of getting it registered. So, I'm considering buying a Bushmaster(complete) or buying a DPMS(buying a complete lower and buying a complete upper and assembling them). I'm somewhat familiar with Bushmasters, but I'm not familiar with DPMS. Which shoud I get and why. If I go with the DPMS, it'll cost around $720.00, but if I go with the Bushmaster, it'll be around $890.00. Is the difference in quality worth the $170.00? Please give me some insight guys! Thanks in advance-ARKAR.
