Lower Receiver

Description

Each order/rifle is hand-built and undergoes a 50-point inspection during the build, including a test fire.  

SHTF-15 Lower Receiver Spec Sheet:

• 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.
  • ALG Defense Advanced Combat Trigger (ACT)
    • Using the same parts as the QMS trigger which comes stock in our rifles, the ACT trigger uses a Nickel-Boron plating on the trigger to increase surface hardness and wear resistance. The internal trigger hammer and disconnector are Nickel-Teflon coated to lower friction coefficients while adding wear resistance. Expect a very crisp and sharp trigger pull each time with this triggers added properties. 4.5 lb. trigger pull.
• 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 every time.
  • Buffer Weight
    • HB2, 4.5 oz.
      • A happy-medium between our heavier buffer options we offer with our suppressor optimized but still light enough to shoot MOST lower powered ammunition. Good middle-ground between ultra-reliability, and a flatter-shooting rifle.
        
    • HB3, 5.5 oz.
      • Best for shooting suppressed/unsuppressed with most 5.56 ammunition, and heavier higher powered .223 ammunition. Very good recoil control.
    • HB4, 6.5 oz.
      • Best recoil control. Suited for suppressor dedicated platforms. Runs best with premium, higher powered 5.56/.223.
• SHTF 45/90 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.
  • TGI Grunt Grip (A2 Variant)
    • A take on the original A2 grip of the M-16, TGI added our own features to step-up the game of this tried and true grip. An aggressive beaver-tail allows for a comfortable and solid grasp all the way around the grip. Stippling was added in key areas around the grip to increase the shooter’s grasp and hold of the rifle. A thumb indent allows for the natural rest of the hand to increase comfortability and make it an easy and intuitive hold for the shooter regardless of position. 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.
  • Magpul MOE SL
    • Similar to the Bravo stock, this allows for multiple positioning on the buffer tube itself, and also features a raised cheek weld for the shooter. This buttstock is slimmer in multiple areas and features a smaller rear portion to allow for better comfort and fit regardless of any armor or other gear which may be getting in the way of establishing and maintaining proper butt-stock positioning in your shoulder pocket.
• Receiver Set | Standard
  • 7075-T6 aluminum forging, MIL-A-8625 Type III anodized | black
