I have this rifle set up with a Magpul PRS OD stock, Hogue over-mold forend , Hogue grip, Phase 5 oversize trigger-guard, and threaded barrel (via Tornado Tech) in 5/8-24 for my AAC cyclone suppressor. I have it set up this way for predator hunting. It has the 20" barrel. I had this posted once before (a couple of months ago) because I want to buy a piston AR and I have a few other AR's so this one does not get used. I had a couple of offers (higher than my current price) but I changed my mind because I got worried that I would not be able to replace it with this current political situation. I am pretty confident (holding my breath) that I can order a piston model now so back on the market this one goes. $1600 Suppressor, scope, and sling not included in this price.
