Dtech AR-15 Gas Blocks

Gas-blocks available in .936",  .875" and .750"    Pricing:  $40.00 or $45.00 laser engraved.  (Custom engraving available)
After years of dealing with issues caused by commercial float-tubes, I decided to design my own, eliminating the bad characteristics and incorporating the good.  My new float-tube has been a huge success, and now I set my sights on another problem area:  The gas-block!   I approached the gas-block design with the same set of goals I used while designing the float-tube:  Get rid of the bad elements, and bring in the desired ones. 

I started out with the .936" diameter block.  The first design is very robust, and a great gas-block, but it just wouldn't quite give enough clearance under a standard float-tube to reliably "free-float".  The second design was perfect, and I now have them in three manifold sizes:  .936", .875" and .750" and all will give you a true free-float under a standard float-tube.

The blocks are a “clamp-on” design, and utilize three cap-head screws to secure them.  This block develops a much better gas-seal between the barrel and block than conventional blocks.
