I just purchased a TAC 15i and am in the process of setting it up. I want to know what people are using for a rest. I will mostly be hunting out of a tree stand and once in a while from a ground blind.
My treestand has a bar on it (no not that kind of bar! ) and I find that with a forward pistol grip I can rest the grip on the bar for longer shots and rest the forend rest on the bar for closer shots.
I use an adjustable shooting stick, (when standing) put it in your pocket and you hold the top of the stick ( the y part) under the forearm. When sitting you put the stick on your knee or what ever works for you, this works well for any weapon (very steady)
