Dear prashantprashantjha19 wrote:One imp factor I missed to mention in my last post is - stroke, that manufacturers alter to conform to legal limits of diff countries products get shipped to. To put an example - the underlever LGU for German market is 70mm stroke and the same one for UK is 88mm, the latter with a stiffer spring and a slightly tweaked TP specs has been reported to deliver up to 17 FPe.
The max stroke alteration that I have been able to manage as a shed tuner is of 13.5mm so far on a local Indian AR....long stroked it from 72 to 86mm. Of course it was a project in itself...quiet nightmarish because it essentially is designed as a short stroke AR. And to extend it beyond reasonable limits required altering everything from the piston size, cocking slot, shaft to base block and comp tube. Of course, the result has been more than worth....super smooth, dead accurate with barely any hold sensitivity, visible energy enhancement and no trace of dieseling . Originally, it was snappy but not once could it shoot without dieseling (typical of short stroke designs).
