Our SuperPremium series rifles leave no stone unturned.  We workover the rifle with extensive gunsmithing enhancements to ensure the ultimate in reliability is achieved.  No one else offers all of what we do.  We go to extreme steps and perform up to 35 processes that are over-and-above any mass-produced rifle on the market. We can’t tell you all the steps we take and perform, but on the occasion that we have read off the list to nay-sayers, their jaw drops before we get a quarter of the way into the list.  At that point they understand our price point and realize it really is a good deal for the money.

Every SuperPremium T-REX15 firearm has its barrel and bolt carefully selected and matched to set the resulting headspace to SAAMI/NATO minimum headspace for the longest bolt life, safe chamber pressures and more consistent velocities.  We can handle any standard pressure domestic military or commercial grade ammunition in 5.56 NATO or .223 Remington cartridges.  Using domestic military and commercial grade, in-spec, ammunition, our minimum headspace setting results in a better seal of chamber gas pressure, and more consistent gas pressure results in reduced precision dispersion.

We also pressure lap the lugs of the bolt and barrel extension together with a proprietary pressure lapping process to ensure all of the lugs are taking and spreading the load.  This goes a long way in eliminating any infant mortality of any overloaded lug pair.

Springs are critical for reliability and our SuperPremium series use only the best on the market.  We only use Colt Gold or Sprinco Brand Ejector and Extractor Springs and flat-wound, cryogenically treated, recoil springs that offer a lower overall charging force withoutout stacking effect, but a higher in-battery load for a slightly longer bolt closed time, reducing stress in the bolt lugs and extractor and longer recoil spring life.

We test and tune every SuperPremium firearm with a combat load-out of 7x 30rd mags and if needed, a bit more. Does anyone else spend ~$300+ worth of ammo proving out each and every firearm?  We break-in each firearm, check each mag for proper operation, check full functionality, tune its gas setting, sight-in BUIS and any Optics to get you well on paper and ensure the firearm is not over or under gassed.  We provide a shot target showing precision capability of each firearm.  This results in an extremely long-life firearm with less heat and fouling in the action, slower reciprocating action speed and lower stresses, and a cooler, softer recoil, flatter running firearm.

Every firearm is manufactured with 100% Made in the USA components (Fab Defense components are made in Israel), with the only exception being a few optics.  We stand behind our brand of firearms and have a lifetime warranty on every SuperPremium firearm.
