The Dirty Bird DB9 MOE+ SBA3 Complete Lower starts with the popular DB9 Glock Mag Compatible Lower Receiver which is then finished with a Mil-Spec Lower Parts Kit, MOE+ Rubber Overmold Pistol Grip and an SBA3 Pistol Stabilizing Brace. It also includes a KAK Industry 8oz Extended 9mm Buffer to ensure smooth cycling.
The DB9 Billet Lower Receiver is an ideal choice for starting your pistol caliber (9mm, 40 S&W, .357 Sig) AR build. Precision machined from a solid block of 7075-T6 billet aluminum and finished with hard-coat black anodizing per Mil 8625 Type 3 Class 2 specifications, you can be sure that this unit is as tough as they come.
This lower receiver accepts any Glock style small frame pistol caliber magazines in 9mm, .40 S&W, .357 SIG, etc. and the mag well features a beveled feed lip for quick and easy mag swaps. Extensive testing and attention to detail also ensure that your Glock style magazines will drop free when released. The proprietary magazine catch and ejector is included and pre-installed from the factory.
Other features include:
- Threaded takedown pin spring and detent hole for easy installation. Set screw is included. Note: To prevent excess pressure on the rear takedown pin and detent, you can shorten the detent spring by the same length of the set screw using some wire cutters prior to installation.
- Threaded upper tension screw to adjust any “slop” out of vertical fit between the upper and lower.
- Ambidextrous finger rests above and below the mag release.
- Threaded bolt catch pin included for easy bolt catch installation.
- Manufactured by New Frontier Armory right here in the USA.
- Lifetime Limited Warranty
Important information:
Magazine Compatibility
This lower will drop-free factory Glock small frame pistol magazines. It has also been thoroughly tested with Magpul GL17 9mm pistol magazines to fit and drop-free. Promo, KCI, Kahn and other types of magazines will also work but due to varying thicknesses relative to factory Glock mag dimensions, slight modification to the magazine catch may be required.
Last Round Bolt Hold-Open
After evaluating many different design concepts from other manufacturers and finding fault in nearly all of them, we’ve designed this lower to use any standard mil-spec or similar bolt catch. Our last round bolt hold open technology instead resides in our matching pistol caliber upper receivers. These billet upper receivers use a PATENT PENDING design which has been proven in numerous field tests to provide the most reliable last round bolt hold open of any that we’ve tested.
Bolt Carrier Group (BCG) Requirements
You’ll need a BCG which is compatible with Glock style magazines. Some BCGs in the market are compatible with both Colt and Glock style magazines but some others are specific. The difference is Glock magazine compatible BCGs have the relief cuts necessary to clear the magazines.
Buffer Recommendations
You’ll want to use a 9mm (extended) buffer which is longer and heavier than a standard carbine buffer. Standard carbine buffers will work but it’s a good idea to use a spacer to limit the rearward travel. This is simply because a 9mm BCG is shorter than a standard BCG which means there is more travel and gives the BCG more time to build speed as it returns home and this extra velocity can cause excess stress on the bolt catch. 9mm extended buffers are common and well worth the investment.
Before firing your new build we suggest you adjust the ejector. You can do this quickly and easily by following these steps:
- Back-off the two hex-head screws holding the ejector just enough so the ejector has a semi-tight “friction fit”.
- Ensure the ejector is seated all the way to the rear and all the way down in it’s pocket.
- Close the upper onto the lower with the bolt all the way forward.
- SLOWLY cycle the bolt in and out about 1/4 of the way back a few times.
- Allow the bolt to close all the way and tighten up the ejector screws. No need to over-torque as this could cause the ejector to shift position, we’ll be adding blue (non-permanent) locktite in the next step.
- OPTIONAL: At this point you can use some dummy rounds to check for proper ejection.
- Remove one ejector screw at a time (ensuring the ejector does not move) and add a dab of blue locktite to the threads and tighten them back down.

Dirty Bird DB9 MOE + SBA3 Complete Lower
Well overall its a great product, that takes some special hands on to make it even better. Mil spec trigger is just that with that extra creep that seems pervasive in the introductory. Check the ejector and magazine catch or release for production rough edges, but these are all fixes that can be easily done. But this mil spec is not out of the box ready for operation. Great finish and mil refinement, ashamed it was not taken to the next level. Disappointed there are not many uppers available uppers that makes this a lock back last round unit. Its like there's a tire missing....a real need for affordable accurate uppers availability for this market..so far no issues of miss feeds nor operation issues. will follow up with photo.
