Inexpensive mess - TRYBE Defense Standard Handguard Barrel Nut

For under a buck I thought what the heck and added a few to my order. I had no issues with threading or torquing to spec on two upper builds, but the OD of the nut apparently is larger than typical. Three different free float handguards would not fit, even with ample persuasion. I ended up taking them off and tossing into my parts bin.
