80% Lowers are NOT a firearm and CAN ship directly to your home. Additional machining will be required to complete the firearm. Purchasing a Jig and having access to a router or mill is required to manufacture this into a firearm. 80% Arms manufactures billet lowers using US sourced aerospace grade 6061 aluminum which is more resistant to corrosion and is much easier to mill than any other alloy used to make lower receivers. Their lowers carry a lifetime warranty. Features:
  • DPMS Gen 1 Pattern Compatibility
  • Type III Hard Anodized Black to Milspec
  • Compatible with both DPMS and SR-25 Magazines.
  • 5 axis CNC machined from billet to extremely tight tolerances
  • Integral trigger guard
  • Semi / Safe selector marking engraved on both sides
  • Ultra-tough reinforced billet design
  • Broached magwell
  • CMMG Mk3 lower Parts Kit is recommended for 80% Arms 308 lowers
  • Rear takedown lug area comes already milled out
*Operations left to complete are as follows: fire control group, trigger pin, hammer pin, trigger slot and safety selector.

THIS IS NOT A FIREARM "NO FFL REQUIRED" CAN SHIP DIRECTLY TO YOUR HOME!!

All GCA and NFA rules apply when you complete this project. Please ensure you fully understand your local and federal laws before completing this 80% blank into a functioning receiver.

At American Made Tactical, we know the lower receiver is the lifeblood of any AR build, which is why we designed our anodized billet receiver for your AR10 80% lower Gen 1 DPMS build. Our receiver is made from 7075 T6 aircraft-grade aluminum and features a new rear take-down slot. This lower receiver was made to fit most gen 1 AR10 80 lower DPMS builds and was fabricated to meet our high-performance standards for the range or field.  Purchase a new black anodized billet lower receiver to finish your AR10 build today.

What is the difference between DPMS Gen 1 and 2?

There are few differences between the gen 1 DPMS AR 10 lower that we’ve come to love and the newer gen 2 rifle. The most significant difference between these two is that gen 1 AR10 80 lower DPMS has been around a lot longer, which means you’ll find much more third-party support for supplies and products when building and upgrading your gen 1 rifle than with a gen 2. To those on a budget, this could be a huge factor. The gen 1 AR10 lower is also a very substantial gun in size and weight, while gen 2 shaves off a few pounds and is significantly shorter. This added mobility and a new design will help with options such as handguards but keep in mind that if you’re going to be building or upgrading any gen 2 rifles, you’ll most likely be stuck with proprietary options.

Are DPMS lowers any good?

While there are a lot of options in the market for a new AR10 lower, the key to truly getting the rifle you want is with a DPMS lower. With a DPMS AR 10 Lower, you have much higher compatibility for parts and upgrades to your DPMS lower build vs. Armalite, and the parts are more readily available. You’ll also be able to interchange magazine types, styles, and brands with DPMS 80% lower. While a lower may take a little bit of work to build, the end result of building an AR10 80% Lower is a rifle that is 100% yours and usually a much more cost-effective alternative to buying a brand new DPMS with the same high-performance shooting capabilities.
