The MOE-K2+ Grip combines reinforced polymer body construction with comfortable, wrap-around rubber overmolding for maximum weapon control in adverse environments. Similar in concept to the smaller MOE-K, the MOE-K2 is a drop in upgrade for AR15 / M4's that offers a more vertical grip angle, but in a full-size grip design. The steeper vertical grip angle is optimized for use on PDW (Personal Defense Weapon) configurations and improves comfort and control on short LOP rifles that bring the primary hand in closer to the shooter's body. With the rubber overmolding for positive weapon control, compatibility with optional Storage Cores for gear stowage, and a unique backstrap design for proper trigger finger placement, the K2+ brings modern styling, ergonomics, and comfort to the AR platform. All mounting hardware and a basic grip cap included. Made in the USA.

Vitrum: Latin for Glass... is just how our "Vitrum" trigger feels. No creep No take up Just a crisp break...like snapping a glass rod. The Vitrum was designed around our True Bolt Action ARs, but it is compatible with your Semi Auto AR as well. When used with a semi auto, the reset is extremely short and positive. The Vitrum is a single stage, drop in unit with a 3lbs break, but it can be adjusted down to just over 2lbs and up to 4.5lbs Obviously, out of all of the triggers we would recommend, this would be the one, not because it is our own, but because it really is the best!

Designed to military standards, the PRS Lite is intended for Mil-Spec USGI carbine/SR25 collapsible/A5 extension tubes* for .223 and .308 receiver-pattern rifles. At 10 ounces lighter than the PRS GEN3, it provides an optimized shooter interface with 0.8” of comb height and 1.4” of LOP adjustments. The low-profile rubber butt-pad is adjustable for height and cant and provides an extremely stable interface with the shooter’s shoulder. There are multiple attachment options for slings, including an ambidextrous 1.25” footman’s loop, a reversible QD sling swivel cup, and space for another optional QD sling swivel cup. Made in the USA.

The Rave 140 curved trigger has a 3.5 lbs single stage pull and comes with anti-walk pins.

Not sure what trigger to put in your UP True Bolt Action AR build? Or any other AR15/AR10 build for that matter? This is the one! If we had to pick one trigger, the Velocity MPC 3lbs single stage would be it. No creep with a crisp break. Easy install and ultra reliable. The 3/8" wide trigger shoe rests a little further forward than a standard AR trigger, landing the pad of your trigger finger on the sweet spot every time. This also results in a lighter feeling pull than the advertised 3lbs. The ArmorLube DLC coating provides a low coefficient of of friction and high micro-hardness. Clean and smooth, every time.  

If you're looking for a 2 stage trigger, that is compatible with our UPR10 True Bolt Action uppers, or any other AR15/AR10 then look no further than the Rise Armament "Iconic" trigger. The Iconic by Rise gives you the control of a two-stage trigger and the crisp, clean break of a single-stage trigger. The first stage is a very smooth and light 1lbs with the second stage breaking cleanly at 2lbs. ***We have had mixed results with using the Iconic with our UPR15 uppers. We only recommend it for use with our UPR10 models.***  

Shorten your AR up with the Law Tactical Folding Stock adapter. With the Law adapter installed, your AR becomes much more compact, while only adding 1.3" to the length of pull. The Law folder is compatible with our True bolt action uppers in both the UPR10 and UPR15 lines, as well as our semi-auto and Modern Sporting Muzzleloader. If you're going to run the Law folder with any of our bolt action ARs, the buffer extension included from Law Tactical is not required.

Turn any "mil-spec" AR15 into a tack driving muzzleloader and catch all the hunts! For our Modern Sporting Muzzleloader uppers, we use the same bolt action receiver from our UPR15 line. The receivers are machined from American 6061 billet aluminum with a pic rail on top and a 15" MLOK handguard which  gives you plenty of real estate for any peripherals you might add. The barrels are a 24", 416R Stainless Steel, 1 -20 twist barrel from Preferred Barrels. Recoil from the .45 caliber projectile is tamed by our dual port muzzle brake. Secured and running along the top of the barrel and protected by the handguard is the aluminum ramrod with brass jag. The bolt is machined from American 4140 steel and features dual extractors to ensure the spent 209 primers won't get stuck. Whether you're an experienced muzzleloader shooter or looking to get into it, look no further. The Uintah Precision Modern Sporting Muzzleloader is it!  

Hit all the hunts with our Modern Sporting Muzzleloader and run your semi-auto upper on it in the off season. Utilizing the same upper receiver from our True Bolt Action UPR-15 uppers, we offer our Modern Sporting Muzzleloader. Our muzzleloader features a Preferred Barrels 416R Stainless Steel barrel. The 24", .45 Caliber, 1-20 twist barrel is Cerakoted black and comes with our ultra effective 2 port muzzle brake which will allow you to be able to push the limits of accuracy in a muzzleloader. The upper is made from American 6061 billet aluminum with a picatinny rail along the top and a 15" MLOK handguard with attachment points at the 3, 6, and 9 o'clock positions. Secured in place along the top of the barrel is an aluminum ramrod with a brass jag. The 4140 American Steel bolt features dual extractors to ensure that spent primers don't get stuck. Ignition is from a standard 209 primer. The lower receiver is our UP-15 6061 billet aluminum "mil-spec" lower. The lowers are built out with a Velocity "Classic" 3lbs single stage trigger, Magpul K2+ grip and Magpul PRS Lite buttstock. The Velocity trigger has no take up and breaks like a glass rod. The PRS Lite stock allows the user to adjust the cheek riser height as well as the length of pull and the rubberized texture of the K2+ grip ensures a non slip surface. Our Complete Modern Sporting Muzzleloader ships in a Plano, All Weather, rolling, double rifle case, so there is enough room for all of your accessories and peripherals. *This complete Muzzleloader rifle must ship to an FFL as it is built with an AR15 lower, which is considered to be a firearm.

If you're looking for something a little different in design for your next AR15 build, look no further. The "Humboldt" from 3rd Gen Tactical is the answer.

Elevation can easily be adjusted with the knurled elevation screw at the rear of the carriage. The aluminum carriage is annodized black, with our Uintah Precision logo laser engraved on one side. Your cannon will come with 3 rounds, 3 patches, 3 fuses (2mm  fuse) and a combo powder measure/tamp tool. Just add your black power and you're ready to go! This is a real, firing cannon! Please know your local laws before purchasing!        

The Amend 2, 6.5 Grendel magazine is what we recommend for use with our 6.5 Grendel AND 6 ARC bolt action uppers. This magazine uses a patented internal and follower design to provide lighter weight, easier loading, and greater reliability than any other Grendel magazine on the market. This is accomplished by stagger stacking rounds towards the bottom of the magazine, and filtering them into a single only stack at the feed lips. These mags feed Grendel and ARC rounds smoother and more reliably than any other magazine we have tested. **These are 10 round capacity magazines.

  The Nomad from RMT is our choice for a top tier trigger. Made from top of the line components and manufactured with surgical like tolerances, there is no other trigger like it on the market. With it's PPT technology, the trigger adjusts to you. It pivots and adjusts with your finger as you pull, resulting in a more consistent trigger pull, every time. The Nomad is a drop in unit, factory set with a crisp 3lbs break. No creep, no slop, no grit. [embed]https://youtu.be/jBC-e8uHN9c[/embed]
