If you have a "like new" Trijicon ACOG TA01NSN or TA31 (with flat top mount), I am interested in trading my AR-15 for it. It's a Rock River Arms lower with everything else being DPMS. It's a 7.62x39 20" HBAR A2 upper and a full stock. I have put about 50 rounds through it, but decided to stick with one AR-15 for now. I'd always wanted an ACOG, but never had the disposable funds available to purchase one. My AR-15 is NOT for sale, only for trade for the above mentioned ACOG's. Cash added (either way) depending on the deal. Pictures available for those who are interested. Email me.
