Hi-desertdog LLC is a FNH Authorized Law Enforcement/Military dealer, type 07 FFL & class 2 SOT NFA dealer, we not only sell firearms but manufacture firearms and Silencers with associated parts too. We do select fire full automatic and SBR conversions to the latest model weapons like the FN Scar, PS90, FS2000, AR15 etc, etc and can build these into "dealer samples" for class III dealers to use and sell from. Hi-desertdog LLC is a gunsmithing machine shop that has 30 years of experience doing serious gunsmithing and manufacturing of firearms and firearm parts. We build new barrels for various firearms (FN, 10/22, 21A, AR, 597 etc) we do threaded pistol conversion kits, threaded accessories, quality manufacture and tuning. We also thread customer supplied barrels to your required size and pitch, including metric and inch, right and left hand threads, even acme types. All threading is done in a lathe with threads centered to rifle bore to prevent baffle strikes.  Hi-desertdog is proud to be a authorized distributor for the great Green Mountain barrel line and we do these in standard or threaded versions. We list on Gunbroker.com under username Hi-desertdog.   Our facility at Staunton Ranch Nevada incorporates private 1600+ meter/ 1 mile  rifle/machine gun range and 100+ meter pistol ranges for testing our products (sometimes we have to wait for the Mule Deer and Antelope to get out of the way). This way we can tweak things and know the products are top notch before they are available for sale. Better we iron out any bugs before you get them.  Hi-desertdog LLC does a lot of work for Gunshops, Firearm dealers, Distributors and MIL/LEO, but we adhere to a strict privacy policy so every job is kept private at our end and is not for us to discus with third parties. We do not export out of the United States directly.
