I can't wait to get this carbine, ordered it 3 days ago. I've been without an AR for about 3 years now and wanted to purchase one similar to my favorite one, Bushmaster Post Ban. I've had 4 AR-15's in a 14 year period in which I've sold all of them. My first AR was the Bushmaster Post Ban. However, not knowing things, I found that the factory pinned/ welded muzzle break on that gun was too loud, almost deafening. The Patrolman M4 A2 is almost exactly like the Post Ban with a collapseable stock ( not fixed in the open position) and a bird cage suppressor. Will add a small rail to the lower handguard for a stubby foregrip. Being in the service and annually having to qualify on the rifle range (late 70's to early 90's), I've grown to love the A2 built in carrying handle upper. This will be the 4th Bushmaster I've owned and don't plan on ever getting rid of this one. The Patrolman M4 A2 is a simple, but reliable, and attractive/ intimidating weapon and is everything that I need it for. The price on Impact Guns was actually $20 cheaper than GunBroker to purchase. Vacation is almost over for the coyotes in the woods behind me up here in the Georgia mountains !
