Works well but with limitations. - Midwest Industries SIG Rattler 10in M-Lok Suppresser Compatible Handguard

I was unable to install this handguard on my Rattler at first, until I realized the upper receiver pivot pin eye had been installed upside-down. Once I removed it, flipped it over and reattached it, the handguard slipped right in place. I also discovered that the maximum inside diameter, with no attachments, was 1.75". Most of the suppressors I've been looking at are 1.7"-1.75" in diameter. With that in mind, you're limited pretty much to suppressor diameters of 1.5"-1.6". It would've been nice if that had been pointed out in the product description. I think I'm being generous with a 4 star rating considering the suppressor limitations and the lack of quality control on the pivot pin attachment.
