TGI SHTF-15 Standard Spec Sheet:

  • 14.5″ 4150 CMV Nitrided Medium Profile Barrel – Mid-Length Gas System | standard
    • We chose this barrel length and barrel material for a specific reason. Wanting to hold true to our ethos of providing reliable work-guns for any use and role. This barrel is both accurate and able to handle a high-volume of fire in any scenario, while maintaining and repeating a high level of performance for thousands upon thousands of rounds. 14.5″ ballistically makes a lot of sense for those wanting to trim barrel length for better portability and maneuverability without giving up too much in terms of velocity. Medium profile to handle the heat build up that comes with longer and more consistent strings of fire.
    • 4150 CMV is a steel-alloy known for its durability and tensile strength. Nitride is a treatment process which is used to enhance the properties of the material being treated. Nitriding provides better accuracy than chrome-lining due to no new materials being added and the nitride imbuing into the steel alloy itself, higher abrasion resistance is gained from the nitriding, as well as corrosion resistance and heat resistance.¬† Trust this barrel to perform for you again, and again, no matter the circumstances.
  • .223 Wylde chamber (multi-cal) | standard
    • Capable of firing both .223 and 5.56 ammunition. This chambering comes with the same diameter dimensions as the 5.56 chamber, allowing it to safely fire the higher pressured 5.56 cartridge, and maintain the reliability in cycling that comes with this larger bored chamber. .223 Wylde chambers however, like the .223 chamber, have a shorter and tighter free-bore and lead. This leads to higher accuracy potential due to the bullet being fired hitting the rifled-portion of the barrel quicker.
  • 1:8 twist rate barrel | standard
    • 1:7 twist is the mil-spec standard, and has been the standard among “civilian” equivalents for years due to this. However, recently many manufacturers have begun to go to the slightly slower rifling twist of 1:8 due to the data showing that the lighter/shorter length bullets perform better in a slightly slower twist rifle barrel. Specifically both the M193 55-grain and the M855 62-grain projectiles. 1 MOA +/- depending on the shooter and ammunition used with most 55-69 projectiles.
  • VLTOR A5 Buffer System | standard
    • Developed for the Marine Corps the A5 Buffer System is longer and thusly heavier than your standard carbine buffer and buffer spring giving the weapon system better recoil control and the shooter a smoother and more controllable shooting experience between shots. Our buffers use the standard VLTOR A5 tube, with a stainless steel buffer and a Wolff XP Rifle spring. We went with this buffer system and components for a specific reason, to give the shooter and users of our rifles the best possible chance at repeating accurate, well placed shots with every trigger pull.
    • Buffer Weight
      • H2, 4.5 oz.
        • Lighter profile. Good ejection pattern. Fastest shot-to-shot. Lighter recoil control.
  • Bolt/BCG
    • DS Arms Premium Complete Bolt Carrier Group | standard
      • Carrier made of 8620 shot-peened steel to increase hardness and wearability, chrome lined to increase heat resistance and extend part-life, parkerized exterior to increase corrosion resistance.
      • Bolt is made of 9310 Super Alloy Steel, stronger than carpenter steel. MPI tested. Hardened steel extractor, with heavy duty extractor spring. Parkerized exterior.
      • Firing pin, retaining pin, and cam pin all made of hardened steel with exterior finishes to increase wearability and corrosion resistance.
  • SHTF Ambidextrous Gas Buster Charging Handle | standard
    • Made from 7075-T6 aluminum, this charging handle in addition to the larger and ambidextrous handle itself which allows for the easy manipulation of the charging handle, also features a raised shelf at the rear of the shaft to help block any excess gas that may be exiting the receiver towards the shooter’s face. A great addition to limit gas blowback, especially while shooting suppressed.
  • Handguard – Rail System
    • Midwest Industries M-LOK Combat Handguard 14″ | standard
      • Featuring a continuous MIL-STD 1913 Picatinny top rail, and then an additional seven sides of M-LOK, this rail has plenty of space for any and all your accessories. With a slim 1.5″ exterior diameter and a 1.3″ inner diameter it is still comfortable to the shooter and easy to get a solid grip around. Featuring rigidity ribbing at the top, and made out of high-quality aluminum, the handguard, while slim, maintains its rigidity and durability at a high margin. Uses a 4140 heat treated barrel nut. Also features two integral anti-rotation QD sling sockets.
  • Trigger
    • ALG Defense Quality Mil-Spec (QMS) | standard
      • The dependability of the standard or stock mil-spec trigger is well known, however some dislike the trigger due to the “grittiness” in the trigger pull itself. ALG honed and improved the standard mil-spec trigger by refining the surfaces of the materials used, using high-quality springs, and machining an overall superior product. The parts and dimensions are all within mil-specifications and parts can be interchanged with other “stock” mil-spec triggers. Consider this as dependable as your standard stock Mil-Spec trigger without the grittiness in the trigger pull itself due to the high-quality machining and manufacturing practices which make high-quality steel and parts. 5.5 lb. trigger pull, although it feels and performs like a lighter trigger
  • SHTF45/90 Short/Full Throw Ambidextrous Safety Selector | standard
    • The SHTF45/90 is an ambidextrous safety selector that can be installed in both 45 or 90 degree throw. With both a short and full (long) throw it is designed to not get in the way of your index finger while shooting or placing your finger along the trigger well. Expect a smooth and crisp lockup when going from safe to fire and vis versa.
    • Safety selector will be installed with 90 degree throw unless otherwise specified in order notes.
  • Grip
    • TGI MP Grip | standard
      • Grip features an aggressive stippling throughout for a solid grasp in all weather and all conditions, a comfortable 15-degree angle allows for a natural and ergonomically sound hold, with a narrower front, and a wider backstrap the shooter is able to get a strong and aggressive grip throughout. An indent for the thumb allows for the natural fit of the hand all the way around. Manufactured from nylon-12 this pistol grip is as durable as it is comfortable.
  • Buttstock
    • B5 Systems Bravo Stock | standard
      • A tried and true carbine stock, allows for multiple positioning of the stock in order for the shooter to find the most comfortable and effective length-of-pull for themselves, also features a raised cheek weld to allow the shooter to find a comfortable and natural head position for utilizing any optics regardless of their positioning.
  • Muzzle Device (All muzzle devices will be pinned and welded unless otherwise specified in order notes. Does not apply to upper receivers.)
    • A2 Birdcage | standard
      • A dependable and solid muzzle device which does a good job at reducing signature, dampening recoil, and dissipating gas. Will be pinned and welded to meet NFA requirements of 16″ overall barrel length to avoid SBR (short-barreled rifle) designation.
  • Receiver Set | standard
    • 7075-T6 aluminum forging, MIL-A-8625 Type III anodized | black
