I have an mtm site n clean rest (bought from wally world). it is unstable. I believe it is mainly do to the rear screw. one screw with a rounded end. after one shot, I have to reset the screw, then next shot I have to put it back to where it was.

this was really show to me after my last range session. I took my bags. only thing I changed on it was I put an board cut to the width of the bag, under the front bag for a little more height.

I am thinking of drilling out the rear feet and putting a couple of screws though them and have dual adjustments. which would be a pita.

the other idea was removing the rear screw and just do the the board trick. the boards would be a 1" x 4" x 4 or 5 inch.

I already have the boards so there is not cost there. they are cut already so no time need just taking the screw out.

if that does not help, I am thinking of just placing my bags on it. just the save my elbow.
