** Still in testing and development. **

This hop up was a necessary evil, through our servicing of the PKM and M60's we have found the hop up options lacking and what has been available....not very reliable.

True to our Stoner 63 hop up, our adjustment wheel has substantial grip to maximize the ability to dial your bb's in. The C-Clip fits perfectly, this little unit is very strong and durable.

STILL IN DEVELOPMENT BUT IF YOU'D LIKE TO BE THE FIRST TO GET YOUR HANDS ON IT.....ORDER UP!
