For this AR-15 Sniper Rifle, Jeff,s idea is to make a rifle for sniper in combat situation. So you do not see extremely long barrel with bipods. And the rear stock is still collapsible like M4A1 and XM177 to improve mobility. Whole gun is based on a XM177E2 model gun kit from Marushin. In appearance, several modifications are made. The eye-catching handguard is one of them and such piece of metal handguard is US made. Barrel is fully custom made by Jeff and the length is set similar to M16A2 barrel. Handle and rear sight is removed and replaced by a scope mount rail. With similar effect to M4A1, scope can be mounted lower and it is easier to aim without cheekpiece. To install the scope mount rail, T shape cocking handle is filed for a better fit. And the scope fitted is 4 X 20mm cross hair scope. The grip is also replaced by the real M16A2 grip.
