I assembled my build this weekend and the Mega Arms Wedgelock Handguard is touching the gas block at the bottom. Should I try and file it down or change it?
Thanks!

Assuming you didn't use red Loctite when you installed the gas block, I would just change it. I believe the BCM low-pro gas block is a little smaller than the Geissele.

I'm curious to know how much it's touching.
My barrels at the smith now for a cut & pin Geissele block with KMR rail, I asked him to test fit clearance before pin and was told passed and pinned.
I may be in the same situation and will post my results if I have to file

I couldn't slide a strip of a business card between the gas block and rail. It's firmly touching. No loctite so I guess I have to change it. Mega Arms said that the.750 is supposed to fit but every product is different. I should have tested it but the handguard is easy to remove.
I had the same problem with the Geissele block and an Erath3 handguard. There was a lot of contact. Had a CMMG low pro block and it worked perfectly. I like the Geissele block because it's very stout and easily pinned to the barrel but it doesn't play well with some skinny rails.

I've used a bunch of the Geissele gas blocks. It's been close on some. But never touched. There is that ridge around the top that could be filed off easily.
