It's a ready to run, highly competitive IPSC rifle/CQB/service rifle/three gun rifle. Mines been stone reliable (I torture test all my toys), accurate (.8-.9 moa with cheap blasting 55gr handloads), The JP trigger is excellent, the rifle is quite light (I don't over swing as much when engaging multiple targets that are widely spaced). Mine wears a collapsible stock (different disciplines, different preferred lengths of pull) and a single point sling adapter. I WAS going to have another custom AR built when the STI's were brought to my attention. The spec is almost exactly what I wanted to build but for dramatically less money, I couldn't say no. Why more people don't have these I'll never know. Guys are constantly commenting on the speed, trigger, and (most of all) accuracy of my STI, yet I rarely see another one. For me, the next step up would be a JP Enterprises CTR.
