KJW MKI Airsoft Sniper Conversion Kit

"this is 23 inch inner barrel and good for kj mk1.

"A must have for your MKI. Once I put this on the accuracy increased by at least 200%. It was a different gun. It is vvery easy to install and I did it by myself in about 1 hour (first mod).
GET IT!

"This is an easy to install mod that drastically increases accuracy, and it boosted my fps at from 450 to 470. unfortunately there is some issue with my trigger that will not let me shoot a full mag while this is attached, an enhanced spring on the trigger might fix this. it comes with a black, metal tip that will replace the orange plastic tip on the mk1.

Pros:
-enhanced accuracy
-higher fps
-makes the mk1 look like a serious sniper

Cons:
-heavier trigger pull
-possible miss feed with weak spring

"Very easy mod to attach.

It helped accuracy a lot, but BBs will not load properly unless you shake the gun before each shot. More of a headache than a good, solid, mod in my opinion
