    Best deal on a complete lower.

    Posted by AMPHAY on Dec 22nd 2010

    If you plan on putting together an AR the way you want it, this complete lower is the best deal at the moment. Function wise, it does what a lower is suppose to do, hold the magazine, strike the firing pin, and buffer/push the bolt carrier to re-chamber rounds. Don't be fooled by the low sale price of this lower. It's worth every penny. Good finish/coating, snappy buffer spring, magazine well that holds colt ar15/m16 mags firmly, and basic trigger/fire controls. It can be completely disassembled for mods/upgrades. Attached to all the mil spec uppers I have without problems. This lower ships straight from the manufacturer to the store of your choice. It took 11 days for it to arrive in my area. Very happy with it.
