AKA's straight pump arm rod is designed to give a straight line push on the back block and reduce torque on the ram for a smoother cycling. The pump arm is also designed with a locking set screw to hold it securely in place to keep the autococker from becoming un-timed. Constructed of stainless steel the AKALMP pump arm rod is the best there is. Available for standard length and mini length.
The AKA Cocking Rod is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
Racegun autococker with all Bonebrake internals and ANS reg and front block
Also cuts down on the twisting affect on back block
I have used just about every pump arm available. This is the best one that has been created. Great design .The offset design cuts the pump arm wear on the body to ZERO.
Also cuts down on the twisting affect that most pump arms have on the back block.....this is the one that I put on all the cockers that I build.
Great sturdy product Stands up to the speed of a racegun ....recomend buying for your cocker
