I found a barely used Bushmaster A2. Model XM15-E2S It's a HBAR that's 11.5" long, with the permanantly mounted flash hider that puts it out to the legal 16" limit. It's also got a 3 sided accessory mount in the front. Like this, only with the 3 sided picany rail. Alright.. Is the shorter barrel something that would affect shootability? Accuracy? The gun's spotless, and has had very few shots through it.. Should I look into this further, or move on? Thoughts?:feedback: Bud's Gunshop has em' for $950, and I can get this for $100 less..
