I got a 14 inch smart parts all American barrel, 6 stage chamber, dye sticky grips, beavertail, new internals, double finger trigger, and maybe soon a storm electronic trigger frame.
This gun is really durable. The stock barrel isnt the best, but it is much better the many other stock barrels out there, it's not picky with pant at all you can use anything with it. It's pretty acurrate. plus the vertical feed makes it easier to aim, you can see down the whole gun. After a little the gt-2000 sticker wears away, but then you can tell people what ever you want about the gun. Plus it's not to much money
right fir the start i notice that it was a little heavy. it weight 3.2 pounds, but dont be a punk and deal with it, besides after a month you wont even notice. that also keeps you from shking when you aim.
I think it is a great gun. I have never had any problems with is, if you are not lookin to spend to mush money on a gun and still want to compet with the big boyz then this is the gun for you.
