I realize it's not exactly an airgun scope, but i hoped that someone may be interested. Leatherwood Camputer ART M-1000. 2.5x10with an M1A mount. So, when my Dad served, he carried an M21. So I wanted to build a clone of one. I didn't want to throw a grand down for the original 3x9 leatherwood, so this was the next best thing. The Cam works the same way. This mount sits much lower than the Springfield Armory m1a mount. A lot lower, it's also made of steel instead of aluminum. Dad says he believes it's the correct mount. Long story short, it's not for me. I don't want to scope my M1A. I like it the way it is, with irons. I've got $500 and something invested in the scope and the mount. I took them out of the box and installed them on my rifle, then immediately took them off. They are both just like new. Selling both for $420 plus help with shipping.. Or may trade for something like an Aimpoint Pro. Located in East Tennessee. Please call or text for quick response. I don't check AGN everyday. 865-773-2255
