I'm looking for a .22lr conversion for my AR. I'd prefer a dedicated M4-style upper, either DPMS or Kuehl. Would also consider an SP1 upper with a Ciener or M261 unit. Or just a separate Ciener or M261 unit if the deal is right.
Can pay with MO or Paypal, plus I have a Colt Mustang and some 1911 and AR parts I could trade.
