Extremely tight fit, hairdryer didnt cut it, but solid handguard. - Bravo Company MFG MCMR M-LOK Compatible Handguard

I don't know about everyone else, but I had a very tough time getting this vanguard onto the barrel nut, im a mechanic who's used to dealing with thermal and press fit parts, and i struggled haha, ended up putting the upper with the barrel nut in the freezer and the handguard in the oven, and had to bang it on with a rubber mallet, that was after giving everything a quick sanding to ensure there were no little burrs or nicks, theres no reason for it to be that tight.

Also had a nice adjustable gas block I wanted to use but found out this handguard is extremely tight compared to other ones so the gas block was actually touching the handguard, I could have sanded it down but then the adjustment for the gas block was also covered so I ended up having to get a UTG slim gas block that was not adjustable.

Overall it's a very sturdy handguard, but then I've also owned bottom of the barrel Chinese handguards that were pretty solid too. The end of the handguard did come with 2 dingsz like someone at the factory dropped it.
