  • Made in the USA

"Awesome product!! As a "drop in" it does exactly what it says, It took my mkm lm4 from 390-410 fps gun (with mods) to a 345-355 fps gun (using propane gas)

However I'm trying to squeeze out a little more fps by slightly shaving down the base of the nozzle in hopes to get me to a steady fps of 380-390 (my field is a max fps of 400) so let the work begin!!!

Pros: It works!
It does what it says in description!
Cons:
It's not adjustable!!!
(Unless you modify it)

FYI: you might wanna pick up a KSC jet spring to go with this part the stock spring is a little on the weak side hope this helps:)

"Disregard my previous, I meant it dropped to 325 rather than around 340-350 which would have been just a bit better.

"Drops too much of the fps? Shave it on the flat end and replace your valve spring with a stronger one. I've installed it in my Kriss Vector and it droped the fps to 290. After shaving it and replacing the spring it went up to 340 fps.
