This is a C and R Firearms custom AR15. Built from an Aero Precision M4E1 lower and features Houge furniture. The stock, pistol grip, and handguard have a nice rubberized texture to them that allows for better grip on the rifle. The bolt carrier group, charging handle, and trigger are mil-spec, which allows the purchaser the freedom to still add to the gun. The optic is a Sig Saucer Romeo MSR. The MSR is a 2 MOA dot with 12 illumination settings. The barrel is a Yankee Hill Machine fluted barrel with a 1/9 twist. Overall this rifle is ready to go for your next range day and a great addition to your collection.
