Disappointing rattletrap - Midwest Industries AR-15/M16 M-Series Two Piece Drop-In M-LOK Handguard

Purchased to replace/upgrade a Magpul SL handguard. The Magpul was a lot more solid. I've tried 2 of these in mid length on 2 different uppers. Even put on a brand new barrel nut, delta ring assembly, and triangle end cap trying to get a solid fit. No dice. There was play in both, even with new hardware. I know that will only get worse over time. Some fasteners pinning the two halves together would fix the problem. MI does that with some of their other rails and should've done it with this one. Honestly, the UTG 2 piece drop in is more solid and more ergonomic, but it's only available in carbine length. I've used the carbine length version of this handguard and it was more solid due to subtle differences in machining, but I wouldn't trust it now either given what I've seen with the mid length version.
