I got the AR15-22 PC first to replace another gun I use in SC and RR competition. Liked how it felt so decided to build an AR for 3-gun competition. Had some parts in hand from a prize table pick from the RR world match, Ergo F93 stock and pistol grip and 2 PMags. So ordered a Stag Arms 3-Gun upper, bought a forged assembled lower wo/stock and added a Geissle Super 3-Gun trigger and one more PMag. Just waiting to get all the parts to put it together and season its 18" barrel. It will look very similar to my AR15-22. Now I have a lot of "junk" parts for it like Ergo rail covers and vertical front grip, UTG bipod, tactical rail light, single point sling, rail mounted laser. Got lots of scopes including 1.5-4.5x32, 1-6x24, and 4-14x44 tactical scopes all mounted on QR mounts. But I only put on stuff when I need to use that stuff.
