If any of you have any expirience building from the diffirent piston uppers stated above then please throw out a few choices to help me decide on the practicle or econimical route to take, the ADDAX's new ZK is nice, but I read a lot of good reviews on the ADCOR, LMT and STAG uppers. Which would be a good pistion upper with the easiest and most Customizable of the four uppers? I really would prefer the barrel to be 16" with the FH already installed and that was the reason I chose the 14.5" barrel. any feed back would greatly be appriciated - Thanks
I highly recommend the LMT piston.
The rail may not be able to be changed-out, but it does sure give you a really nice, solid, sturdy rail.
Plus there are now companies able to fab up custom barrel extensions, to use other barrels with the MRP CQB upper, but it would definitely help for LMT to start selling the piston gas block separately.
