9-13" pivot bipod and possibly an A2 adapter

[sasquatchoslav]

Digging out and old AR my dad loves since he is living local now and want to spruce it up with a bipod for him. Harris is so nice, but given how long my Caldwell has held up I think I'm going to stick to a lower cost option this will be a bench maven only. Gotta be 9-13 and gotta be a pivot. Have the old school A2 handguards so if you have an adapter that comes with great if not can buy that on my own. Just wanted to check in here and see if maybe someone bought a 9-13 and found it wasn't the right height range.

Feel free to include a pic, details or price to me if you want to streamline our coms.

Thanks all
