john,
the sight rail you're using is too thin, and your hengstler is still too low.
it can be fun to work out the details! I know it's hard to do!
you should be using the 16mm steel, with cutouts at the rear.
and keep in mind that your hengstler should overlap the mag well, and be at 1/2 height to the scope's horizontal.
the hengstler should be just about half the scope's height to it's top edge.
this will allow for clearance for the folding stock arm. the mounting for hengstlers was really really close to the body of the
gun as well. you have it a few MM's out to far from the side.
man I love how real sterlings look!
keep up the good work on this... we all know you won't give up till it's perfect!
GINO has T Track, and SABREFREAK on the RPF has track.
I have some sabrefreak track and it's nice and all, but to really do this project true justice you
probably should go with the GINO track. he has almost the exact style used by LFL.
it's really expensive, but worth it! sabrefreak track seems a little thin.
to do it right you have to taper the width at the end just as they enter the vent.
and the width needs to completely cover all the holes. none should be seen like on the SDS blaster.
