Ok, so this is what I found so far. I disassembled my Scorpion down to the Barrel and Receiver assembly and took some measurments by placing a straight edge on the top of the receiver and checking the differences between the muzzle end and chamber end with a square. My measurements indicated that the muzzle end is lower by 3/64" using my non scientific method which doesn't really say much. So I took the halves apart and found that the fit between the Trunion and the receiver halves are very close. Nothing can really be done without taking a big risk and turning it into a expensive paper weight. I know the left halves are available for purchase and the right half is not. So I reassembled the receiver using 15 inch pounds with loctite on each screw and put it all back together with the exception of the hand guard and the left side sling loop. I got tired of scraping my hand on it when operating the charging handle. If anything I'll install a Magpul Mlok QD on the handguard.
What I did with the HB Industries hand guard was sand down the one end at an angle to level out the hand guard with the receiver's picatinny rail. Started with #80 grit to get it roughed in then test fit it to the receiver till it worked out. Then I stepped it all the way up to #1200 grit.
It didn't take much to shape the end of the hand guard, and polishing it off with the finer grits was pretty quick work. If you decide to try this out, proceed with caution and at your own risk! Then again it's a $50 part. I wanted to save this part because I think it just looks so cool and I agree with others out there making the Scorpion look like a HK UMP.
Here's the end result. I decided to move the C-more sight to the back because it kept on interfering with my HK slap technique. Something I've been perfecting for may years with airsoft guns. The irons are there purely for backup and the placement is similar to what some people do with their handguns utilizing a RMR and irons. I'll be taking Anya to the range tomorrow with hopes that correcting the handguard will fix my sight alignment problem and that my sight configuration will be feasible.
Wish me luck!
