Next, is to assemble your bundle by scanning the different gear options. If it's a cleaning kit you're building, you may see a variety of options for brush calibers, solvents, and even cleaning pads. The gear options are shown in tiles and you simply need to click “Add to Bundle” for the items you need. Additional gear information will appear if you click the 'i' in the top left of the gear tile. Keep in mind, the more gear you select, the more you save. And as you grow the number of items in your bundle your discount will be shown in the top right of the screen. Here's how discounting works:

  • $25-$50 combined orders receive 5% off and free shipping!
  • Combined orders over $50 receive 15% off and free shipping!

Bundle!: Add To Cart & Purchase.

Once you add the first item to your bundle, a status bar will appear at the top showing the number of items in your bundle, a button to view your bundle summary, and sum of your building discount. At the bottom of the screen, you'll see the bundle price and simply click "Add to Cart" once your bundle is built.

And of course, if you need additional help with buidling your own custom bundle, don't hesitate to contact us.

Product Description

Inventory is in short supply. We are taking orders and will manage a backorder list. Most items ship within 4 weeks.

The M5 Upper Receiver from a custom designed 7075-T6 Aluminum forging patterned to the DPMS High Profile standard. This upper receiver is compatible with all standard LR308 components. Additional features include laser engraved T-markings and feed ramps for reliable chambering. 

The M5E1 platform starts here, with the M5E1 Upper Receiver. The M5E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Through superior engineering, the parts needed to mount a free-floated handguard have been condensed to a mere 8 screws. Since the handguard mounting surface and upper are of the same forging, not only is it a stronger system, but additional lightening cuts save weight and allow for more efficient cooling.

Simply insert your barrel assembly into the M5E1 upper, tighten it using the included barrel nut and slide your rail on and tighten the rail screws. Within minutes you have a modular, free-floated rail.

Compatibility - - Accepts standard DPMS .308 components

Please Note- The M5E1 Upper Receiver is specifically designed to be used with our M5 Enhanced Handguards. It will not work with other AR10/308 handguards.


  • M4 Feedramps
  • .2795 Takedown pin holes
