New UK Spring-Designed to work in many guns


29 coils x .120 inch diameter wire- ID is .556" 

This will work in the AA series guns and many HW guns etc.

Geared to be adjusted to under 12 ft. lbs. to just into the FAC range with spacing.

Can be used on  soften the HW50-R6-HW99 and on and on. ( Straight Drop In)

Many AA guns could use this as it is .360 inch less spacing than the OEM TX-PS spring.

For easiest installation order it preset. You can also use our .790" washers or power spacers.

Can be adapted to the older TX guns from late 1992 on and even the UK short stroke guns.

With AA guns make sure you put fresh seals in- most owners don't and they require it periodically
