So two weeks ago i posted "didn't fit over my gas tube" - Sharps Bros. M-LOK Ultralite Handguard

I went on about how the Wilson Combat said their "Bullet Proof Adjustable Lo-Profile Gas Block, 0.875 ITEM # TR-AGB875-R" would fit with any MILSPEC hand guard. I spoke to them over the phone when I ran into this issue. They said with authority it would fit... So I returned the two hand guards I purchased here and replaced them with a Wilson Combat one. Still didn't fit to my standards. Free float means no contact. They didn't seem surprised that they didn't fit when I called them back.

If you are putting together a normal gas block these hand guards will fit fine.
