i m getting my tightbore barrel upgrade JBU-KUAN 6.03 mm this weekend on my SIG552. i cant tell u now, but so far with new tightbore 6.03 mm on my JG HK416, the accuracy improves a lot. More groupings!. Love it.
Does anyone know what's MArui SIG552 original inner barrel size?. Is it 6.04 mm or 6.08mm?.
And any more suggestions for improving my JG HK416 performance?. Well out of the box is already 435 fps. But i heard the gears need proper shimming,if i want it last long...hmm..i dunno how to do it?. Any suggestions of specific parts?
