Hand guard is great. - Yankee Hill Machine AR-15 12.25 Inch Rifle Length MR7 M-Lok Handguard, Includes All Tools, Parts, and Instructions

The YHM handguard is machined well and a good fit and finish but it does NOT come with the tools that OP says it does. When I contacted them they told me to contact YHM and they said it does not come with tools. Tool is sold separately. Contacted OP again and waited. They offered me $4 off of the tool from them. As of this writing it is still listed as coming with the tool. OP has good inventory and prices listed on the website but beware of changing prices, backorders, slow shipping and late tracking updates. My experience is that they over promise and under deliver. BTW the tool is not necessary to install hand guard it just helps with the jam nut installation.
