Great gun, in 1989 I agonized over it or Combat Elite. Went w combat elite and for many years I thought I had been penny wise pound foolish because I ended up adding & paying for those refinements. (Tgt trigger, adj sights, fitted bushing & the list keeps on going). I was shooting IPSC.
My only comfort was seeing Arnold use my gun in Terminator II.
My lesson learned: Unless your a DIY guy - buy it the way you want it right out of the box.
