7.62 NATO & .308 7075-T6 Forged Flattop Receiver with Picatinny Rail and Forward Assist 16" Stainless Steel Match Barrel with an advertised 1 MOA accuracy Triple Lapped RH 1:10" Twist 4 Groove A2 Flash Hider Aluminum round free-float handguard Picatinny Gas Block (.398" lower than receiver rail) Forged Lower Receiver A2 stock I did not buy the rifle as a whole unit - I bought the complete upper receiver directly from Armalite last year but picked up the lower receiver used a few years ago. I'm not sure what kind of life the lower receiver went through before I had it but it's performed flawlessly for me since I've had it (it does have a scuff at the bottom of the magazine well though). The upper receiver has less than 500 rounds through it and is in perfect shape except for the tool marks that I so bone headedly inflicted on the barrel upon switching back to the factory flash hider from my muzzle brake. The charging handle has been upgraded with a Badger Ordnance lever but the original lever is included in case it's not to your liking. If you're not familiar with the Armalite AR-10s, they have two different series - this one is their B-series and takes only Armalite steel magazines (unlike their A-series that will accept either their old waffle magazines or 308 PMAGs). The receivers between the two series are NOT interchangeable. I'm asking $1550, including two 20 round magazines and the Plano hard case Armalite ships their rifles in. Cash offers only, please.
