handguard for bull barrel with adjustable gas block

[lbsand]

I've built a 1/2 dozen or so rifles using Superlative Arms Adjustable Gas Blocks.  I've never encountered a clearance problem with Handguards from Geissele, Centurion Arms, BCM, SLR, Forward Controls Design, ZEV or White Oak Armament.  The HG from White Oak is an outstanding value at <$150 and they'll even loan you the Barrel Nut Adapter.
