Rail will move forward - Midwest Industries 10in Combat Rail T-Series One Piece Free Float Handguard

If you look at the picture it shows the retaining plate that is sandwiched by the two bolts. Maybe if those holes weren't egg shape the handguard wouldn't move forward. I mounted a scope on my pistol and this handguard moved forward and the scope will not hold zero. I torqued it to spec and used thread locker on the threads. There is a gap at the back of the handguard that wasn't there before I started shooting. Maybe it would be fine if I didn't have a scope on it, the anti rotation feature seems nice, but the retention is flawed. This is probably why this is discontinued and it says on their site all sales final for this model.

Take a look at how many of their handguards are on the second and third generation and compare that to any tier 1 company and you'll see MWI is the only one that has generation two and three for a number of handguards. It speaks volumes about the quality and function of their handguards. Now I know why real handguards are very expensive.
