What kind of ammo you running through it
You may have issues with Norinco or wolf.
Mine is a little finicky really like heavier bullets
Upgrade your extractor spring and o ring.
honestly, not sure, does norinco even make both? ive shot it through my ddmk18 no problem and havent ever thought about it
n00b question: when looking for a rail is there anything i need to consider on the pdw re: gas tube, or pinning, etc?
from my research the kx5 is 1.2" and the rail i want is 1.3" internal diameter - so should fit no prob
The kx5 is basically the proven kx3
Redesigned by request to fit inside all rails.
You will have no issues.
No
