Ed Torgerson's Review of UTG Pro M-LOK AR15 15in Ultra Slim Free Float Handguard

The tool for tightening the barrel nut on was made of cheap pot metal and shattered when I tried to do the first cycle of tightening to 30ftlbs and then backing it off. Luckily I was able to use a normal castle nut tool on the back of an armorer's wrench to loosen and tighten it back to spec. Aside from that the handguard looks nice, it within spec, and seems fairly sturdy while also being lightweight.
Pros:
  • Light, durable, in spec mlok, looks good
Cons:
  • the proprietary wrench they sell with it is absolute garbage and broke immediately under almost no force
Best Used for:
  • only buy this if you have a castle nut wrench
Would Recommend: Yes
