I have two of these I put together last winter using all RRA parts. The stock is a 4 position which RRA sold quite a few years ago. They have the standard trigger and have never had an upper pinned to them. They are new and unfired. $225.00 each delivered or both for $435.00 delivered. SPF PMO only -NO PAYPAL. Shipping to your FFL in the first 48 only.
