The Smith & Wesson AR15 military and police edition in my opinion is definitely a "bang for your buck" product.  We're talking about the M4 model, milspec AR 15. I have owned this assault rifle for about a year now and have ran 5,000+ rounds of steel and brass casing through this gun, and have yet to have any problems.. not a single jam up. This rifle is durable and is greatly customizable. The barrel is 16 inches and chrome lined with a 1 in 9 twist. It houses a 5.56NATO/223 round. The weight is approximately 8 lbs with a trigger pull of 7lbs. With the butt stock extended it is 35 inches long, 32 inches collapsed. The recoil is manageable by all means, even for a small woman like myself. I definitely recommend this assault rifle to anyone that doesn't want to go broke buying a dependable gun.
