The GXE is a good gun. The GXE will compare to a E-Orracle and Nightkast. I hear the LPR is very consistent, along with the reg. The one thing I do not like would be the back block and bolt design. This design will not let you get an aftermarket bolt that isn't from ANS. You can change the back block but some people don't like how the new back blocks don't flow with the milling. Just make sure to get a fast ram to keep up with your fingers

. Though you might want to try a Race Frame and an E-blade and decide which one you like better. I am not sure where you can find those short barrels, you might have luck calling ANS. I would suggest you get a barrel kit though.
