Here's a little info and pricing on the upper receivers we're building here at HDI.
--------------------------------------------------------------------------
Our basic HD4 upper receiver can be built in numerous configurations, it all depends on whether you want to stay "mild" with our entry-level HD4-MOE or if you want to upgrade to a free-float railed handguard. Right now we're primarily using Daniel Defense's AR15 Lite series of rails as well as LaRue Tactical's excellent series of railed handguards. For the folks who are looking for a lightweight no-frills option, we'll be offering the Troy Industries TRX "Extreme" handguard soon.
All of our HD4 uppers have the following specs:
- Lothar Walther LW19 16” M4 gov’t profile barrel, carbine-length gas system w/ A2 flash hider.
- 5.56NATO chamber, 1/7 twist w/ chrome lined bore.
- Fixed front sight base, “F” marked for M4 flattop receiver compatibility.
- Young Manufacturing auto bolt carrier assembly.

If you're looking for a serious upgrade to your AR, then our HD4[SPR] upper is worth considering. My intent wasn't to create a faithful reproduction of the Mk12 SPR upper receiver - I wanted to produce a modernized and improved version using the best components available today.

- Lothar Walther LW50 18” SPR profile barrel, rifle-length gas system w/ Smith Vortex flash hider.
- .223Wylde chamber, 1/8 twist w/ polygonal rifling. IonBond finish standard or optionally available with bead blast finish.

--------------------------------------------------------------------------
Our upper receivers are built one at a time, not on an assembly line or in large batches. Every single one of them is test-fired before it goes out the door to confirm it's functioning 100% reliably.
When you decide to purchase an upper from us, be aware that not everything listed is in-stock or immediately available. We usually have a few of the HD4-MOE upper receivers available as well as the 10.5" SBR versions, but if you request an upgraded configuration we may need to have specific parts (such as the railed handguards) ordered.
