Rock solid - Midwest Industries AR-15/M16 SLH Free Float Slim Line Handguard

I put this on my LE6920, after removing the front sight post/gas block, the “D” ring and the factory barrel nut. The lockup is EXTREMELY tight! The rail itself, has alignment tabs, that are molded into it, so alignment is perfect, every time. Unlike some handrails that have removable alignment tabs. Once mounted, this rail doesn’t move! It’s extremely solid, without the added weight. I have the 15”, for the factory Colt’s 16.1” barrel. The adjustable gas-block I chose, is the Superlative, with set screws. After seeing one review that said the rail didn’t fit with the clamp-on version, I didn’t want to take a chance that it wouldn’t fit. I will say this, there seems to be plenty of room, but, again, I didn’t try the clamp-on version. And finally, the “T” marks are highlighted in white, though not as bright as the Colt receiver. That, my friends, is the only hit, I can give it. Would I recommend this? Wholeheartedly yes!
