Replica Bulgarian Gas Block & Front Sight Combo.
Manufactured from 4130 Steel, hardened to C 42-44 then nitrided. Thread are 24x1.5 metric, just like the originals. These are NOT chrome lined, but nitrided to achieve the same wear protection.
Sold without windage drum and sight post, without plunger and spring, and in the white.
Important Notes: Be sure to check clearance on ALL dimensions prior to pressing onto your barrel. Requests for returns/refunds will not be honored if the sight block has been installed on the barrel. Pin holes are manufactured undersize to prevent the bit/mill from "walking" when it hits the barrel. The sight WILL crack in that area if you don't drill to proper size and try pressing in the pin. Also, the webbing around the windage drum is thin. Carefully check the dimension of your windage drum compared to the windage drum bore. The proper dimension of the windage drum bore is .0003"-.0005" (that's three to five ten-thousandths) smaller than the diameter of the windage drum.
Some folks have experienced difficulty installing muzzle devices. The threads were purposely cut oversize to allow the application of suppressors. Most of the time, simply threading the muzzle device on and off repeatedly (may require significant effort) will result in the threads loosening sufficiently to engage the detent. If you receive a block which doesn't allow installation of a muzzle device, please contact me for remedial action/replacement. Check this out prior to pressing onto your barrel! Requests for returns/refunds will not be honored if the sight block has been installed on the barrel.
