Guarder tight bore and KSC hopup chamber --> Works, but needed some minor modification. Had to dremel a tapered slot for the ball bearing to move through for it to be properly adjustable. Am now getting awesome consistency and range with an a+ studio bucking, .25-.3 work great, haven't tried .2's yet.
Picked up an mp7/system 7 NPAS to install in my lm4, and decided to look for instructions to disassemble the nozzle (better safe than sorry) and in the process found some new threads about the NPAS that confirm that NPAS will NOT work in the LM4 without modification. So... I was dead wrong, I apologize.

Well the NPAS DOES technically work, but will lower your overall FPS compared to stock. So trimming it here and there to allow for more gas to go through would "fix" this. A pretty simple and quick fix.
That being said, RA-Tech has a Nozzle w/ NPAS, and even complete BCG + N Nozzle + Npas on sale for the KSC M4 GBBR. They confirmed me these would work fine with the LM4 ASIAN version. I haven't inquired about the US version but the BCG and Nozzle looks pretty much the same to me; But take this with a grain of salt
About the Guarder hopup, do you have any pics of the mod? I will most probably change mine at some point as I always have over hop with .28's
