Product description
Midwest Industries Gas Block: Upper-Height Picatinny Rail for Backup Sights
Features
- Upper-height design matches A-4 flat-top receivers
- Picatinny rail for mounting backup iron sights or accessories
- Fits .750″ diameter barrels
- 4141 steel construction
- Black finish
- Machined for precise upper receiver alignment
The Midwest Industries railed gas block solves the sight mounting problem on rifles with low-profile handguards by providing an upper-height Picatinny rail that aligns perfectly with flat-top receivers. This gas block works well for builds needing front backup iron sights without a front sight tower, rifles requiring consistent sight plane height, and anyone mounting accessories at the front of the handguard. The machined 4141 steel construction matches A-4 upper height precisely, eliminating the elevation misalignment issues that plague mismatched gas block heights.
