I got the Magpul MOE SL carbine length Hand guard from a CGNer recently.... Its not fitting too well..

I've spend a few hours trying to make it for (seen and tried to follow a few YouTube videos) without any success...

Anybody have this issue and what was your resolution??

Cheers!
 
The Norinco barrel nut also seems to be slightly longer in length than standard NA/milspec parts size.

If you look at where the wrench sprockets are on the barrel nut (these are what rest in the groove at the base of your standard hand guard) I have found most of the time the barrel nut "teeth" will be past the groove in the handguards.
Most of the ones I've had to fit I had to dremel the groove in the handguard about twice as wide so the teeth sill rest in the groove.
Your mileage may vary though.

Changing the cap is easier said than done. 1/10 times you will drive the FSB pins out easily. The other 9/10 times you will smash them into a mess and end up cutting the whole FSB off lol
Ask me how I know....
If the cap is actually a little tight, you would do better to sand/dremel that end of the guards until they fit in the cap.
 
Good points! I've had to sand down the lips of the habdguard already to fit... But probably a tad more will help.

Noted on the bottom channels too. Just not a while lot of material to widen...

I know.
It's a touchy game.
You can always fill the channel with a high quality marine tex/devcon or high strength/high quality resin epoxy and then carve/dremel out a new channel all around the inside for the barrel nut sprockets to sit in at the proper spot. Hard to explain in words.

Conversely, you could always carve the front end of guards back or notch it so the cap rim (and the front tip of the guards) will go deeper into the front of the guards.
You would have to file the front face of the portion that goes into the cap back and this would bring the rear of the guards forward and may line the channel up with the nut sprockets.
The MOE guards installed you can't even see the handguard cap, the guards cover the cap and insert area, so even if you are not very handy as long as it fits tight and stay on then mission accomplished :rockOn:

If you were closer I would give you a hand Sir.

lol Aye I agree.
That's the price you pay though with AR15's (especially Norc) I had to get my norc barrel FSB off so I could put a triangular cap and change the barrel nut.
I had to cut the thing off, the pins would just not come out.

Think about like this, it doesn't fit. You already bought it. The money is spent. Your time/labour in the basement making it work don't cost anything ;)

See the other idea I posted above after you quoted Sir.
 
The frustrating part is that if I put the bottom in by itself.. its fits okay.

The top part is a pain, but I get pop it in eventually.. and doing a dry fit (putting them together not on the rifle) they go together just fine!
 
I got it on!! This thing is never coming off... Unless I hack it for a FF quad rail
