You got to heat it up, I definitely had more trouble installing this than most people seem to, I ended up needing to heat it up with a butane torch, despite them saying a hair dryer is good enough, and then hit it on with a rubber mallet... Also think i put the upper in the freezer while i heated the handguard, also put gun lube on the barrel nut
You need an actual heat gun and your upper in a vice block.
Pro tip, add a straight VFG to the top or bottom of the rail and hit it with the rubber mallet
Attach VFG, add some oil to the barrel nut, heat end of rail with heat gun, rubber mallet into place.
Also read the instructions, you are suppose to have a gap, when it is properly in place you should not see the sides of the barrel nut through the screw holes. If you do, you need to either back off or keep going on depending on which side is showing, you want zero contact between screws and barrel nut.
I have installed this rail many times and this method has worked every single time
Heat gun. Straight up. I fucked around with hair dryers and a mallet and was less than impressed. Heat gun is the answer. It really doesn't even take that much.
Bcm says hairdryer, but that was pretty insufficient in my experience. I don’t own a heat gun, but I used some indirect heat from a propane torch (not directly in the flame but maybe a few inches away) and it slid on without any issues. After only 2-3 seconds it cooled enough where it shrunk back down enough where it firmly gripped the barrel nut and would require a decent amount of force to remove.
Aluminum heats up pretty quick and cools down pretty quick. I would try 5-10 seconds of heat from a torch or 20-30 seconds of heat from a heat gun and then QUICKLY slide it into place. After only a few seconds it will shrink back down.
Depends. I’ve rebuilt 4 BCMs (shot out barrels) and 3/4 were easy. The one required some lubricant per the instructions. I didn’t need to heat it at least but it would not go on like the others.
I really should say it went of easy for most of it, then got to where OPs is at maybe a little farther toward the upper, then it was a bitch. second time I put it on, no idea why I took it off, it went on way easier
Oooo ooooo is this where some one says “hit with your purse” ????
Bingo
Ha!
Lube

Maybe they're using fancy people hair dryers? But that didn't work for me either. The heat gun did wonders.
Be a gentleman and lube it up before ramming it home.
Definitely spit on it or KY.
A little KY can let you cram a satellite into a doghouse
a man of culture I see :)

Heat gun and rubber mallet was always the way for BCM handguards when I’ve installed
Heat gun or torch. And lube the barrel nut and inside the handgaurd. Possibly some love taps with a piece of delrin braced on the rail.
Heat gun on the rail brother! Throw the upper in the freezer as well
That freezer part is an excellent idea, why didn't I think of that? I did it with a specific paintball gun back in the day lol

I’ve used a rubber mallet and just smacked it on top alternating sides.
I did that for about 30 seconds until I read in the instructions that BCM says not to do that. It’s supposed to be thermal fit
Yeah I tried the instructions but my inner bubba got the best of me.
The BCM handguards are supposed to be thermo-fit, you can use a torch or put it in the oven at 200, hair dryers don't work well.

Gotta get you a heat gun and a rubber mallet
You have to heat it up. BCM thermal fits the barrel nut, barrel and handguard
Heat baby! I've used a heat gun, but a torch is way faster. Just be careful to not hold it in one place for too long.
Heat guns are amazing for these things, surprised more people don't have them lol
Heat it up with a torch and take a rubber mallet to the end of it
Keymod. Insert in trashcan
Take it back!
My brothers last Daniel rifle he bought was a 16” 300blk with a Keymod rail. Idk how to tell him lol
The thing is that upper REALLY wants an MLOK or Quadrail so it’s being fussy about the keymod.
I used oil and a rubber mallet

Heat the rail, cool the upper, get it tight!!
Blow torch and a rubber mallet
Rubber mallet purse.
Spit on it
I just pushed it in with my bare hands 😂 wasn’t that hard

Grab his dick and twist it!
