I'm a bit crippled up to. I hunt sitting in an old steel lawn chair in a ground blind made of dead fall with a fairly sturdy limb for a rest. Have an old golf cart for travel. If I were you I'd look for a soft kicker. Not sure what cal the ar-15 is but the Mar 336 if in 30/30 or 35 Rem can be loaded down to very soft recoil. Not too hard to put a riser on the stock. Over on the MarlinOwners site is quite a bit of info on that. Today on that site in the 336 forum is a pic of a nice looking homemade stock riser. I love mouse fart cast loads in the 30/30 and 45/70. No kick, plenty lethal. Hunting in my ground blind, I always cover my face and hands, never ever used a scent killer, have had at least half a dozen deer within 2 feet nibbling on green limbs I stuck in my blind. Much fun. Think a bit outside the box.
