If you like bullpups and are a Marine (No such thing as "former Marine"), you might like to shoot some of my pups and carbines. I'm a member up at Young's Longshot Range where they have steel plates and backstops for paper, all the way out to 1,000 yards. I like bullpups too and have the FS2000 and an MSAR. I've got a couple .45 acp carbines and a 9mm carbine. If those don't work, I have a .338 Lapua and a Rem 700 in .308 that I shoot out to 1,000 yards.
I'm going in for a total knee replacement but should be ready to shoot in a couple months. I'll try to contact you once the knee heals and we can go up and play with some of the toys. Here's the FS2000 with the ACOG and Docter red dot ( and a few more of my FN collection).
