Anyone have experience with one of these?

Sorry for the delayed reply, but I haven't been to the forum in quite a while.

I own a State Arms Shorty. However, it is now, highly modified. I shoot it in FCSA Matches and truly like it. I will say, I did not like the stock brake (fish gill) at all. With my match loads, it hammered me quite a lot.

The action, bolt and trigger, are about the only "original" parts still utilized.

The action was inletted and bedded in a Manners Carbon Fiber Stock. Barrel we replaced with a Feddersen 34"  1.750" Barrel (Full Length). Brake was replaced and I went with an Armalite AR-50 Brake. It totally made the gun more manageable.

Here's a video right after rebarreling, but before it was moved into the Manners CF Stock

I have pictures of the finished gun, but do not see a way to directly post here?
