Here are my long range guns. My SPR clone has the same barrel and bolt as the original the rest are just personal touches. The big bore is the DPMS SASS. This one is rare because it is one made for the government trials. It has the step down barrel for the Ops Inc can (which she wears) and the barrel is huge and flutted under the handguards. Both now wear MKIV Leupolds. The SASS is a wonder of modern manufacturing. I can hit steel at 1200m all day long and do fairly consistant head shots at 700M. Our Group CW5 has really helped me with my long range work and thanks to him I do pretty well in the regional Guard matches.

My CQB gun is a complete custom gun. 11" barrel with the AAC SPR/M4 can and all the goodies you see. With MK 262 ammo it cranks out good velocity and is accurate to 200m (have not tried it past that yet). Even with the short barrel it is hearing protection safe.
