I have a Hatsan AT44-10 and with its walnut stock its a heavy rifle. Do they make a synthetic stock for this rifle? I use mine for both target and hunting and do a lot of spot and stock. After a while of going up and down these hills this rifle begins to feel like a ton of bricks. I recently installed sling swivel studs and a sling, but would still like to lighten it up a little if possible. Can anyone offer up any help or information on where I could find a stock/ Thanks, Mike.
