I am completing my first custom build. I installed the Geissele Super Gas Block .750 and the handguard is a Mega Arms Wedge Lock. The gas block is firmly touching the handguard on the bottom. Does anyone know which gas block will provide good clearance? I emailed Mega Arms to see if the know which brands fit. On the phone they just said low profile which seems to mean different things to different companies.

Thanks!

You probably just need a simple set screw gas block; one that doesn't have a provision for a cross pin. I have a SBG as well and it does seem to be a little bulkier on the bottom than other gas blocks I've used.

The Geissele block is wider at the base. BCM has some smaller options.

Depending on how much its touching, why not file it down and cold blue ?

I use MI handguards and the only GB I have found that does not need the bottom thinned down is the TROY lo-pro GB.  All the other LP GB I have used, including MI's, need .050 to .075 taken off the bottom and the set screws need dressing down also, don't forget about them.

This is one situation where guns and Dremel tools can go together nicely.
