Forward Controls Design - GBF - Billet .750 Gas Block

The GBF - Billet .750 Gas Block is machined from heat treated 4140 bar stock, The GBF is manganese phosphate coated, GBF holds rather tight tolerances to squeeze every bit of tight seal we can from the design. GBF's gas tube hole can be described as semi blind hole, in that it has an access port just big enough to allow a 3/32 punch to go through. Bosses on both sides of the GBF to give gunsmiths an easy reference point to pin the GBF to the barrel. Both 5/32x5/8, and 1/8x5/8 pins can be used to pin the GBF to the barrel. Its set screws are 0.450 apart. A gas tube pin, two knurled set screws are included (3/32 wrench is required.)
