Here's one I put together. Its a Delta Company Arms 9" upper, with a MWI forearm that is 10" long. Using an AAC Cylone suppressor, it's quiet, fairly short overall and very accurate. Its on an SBR'ed Bushmaster lower and it sports a Magpul stock and grip. Its 100 percent on the cycling using Remington 220 Subsonic rounds. While its not the quietest load that I've shot, its not bad. Of course, the Remington is made to function in an AR and it does that quite well. Whatdya think? Do you like the way it looks or not?
