Angstadt Arms Integrally Suppressed UDP-9iC

There are phrases that excited any red blooded gun owner. Cheap ammo, range time, belt fed, and… Integrally suppressed.

Angstadt Arms’ upcoming UDP-9iC will be an integrally suppressed version of their standard UDP-9 pistol caliber AR-15 upper receivers with integral suppressors from KGMade Suppressors. The UDP-9iC uppers will be available in SBR/Pistol configuration with an 11.9″ barrel (6″ barrel, 5.9″ core) or a longer 16.1″ barrel version. These uppers will be compatible with ANY 9mm AR-15 lower.

Angstadt Arms Shipping UDP-9 Receiver Sets

It has begun! Angstadt Arms is now shipping their UDP-9 receiver sets to dealers. If you aren’t familiar with the UDP-9, you can check out our previous post. Visit the Angstadt Arms dealer page to find all the dealers that will be stocking the sets.

Angstadt Arms’ plan from the beginning has been to release the receiver sets first and then move on to offering complete UDP-9 Carbines and SBRs. If you have been waiting for the receivers so you can build your own, your wait is over. If you are waiting for a complete UDP-9, you won’t have to wait much longer.

Angstadt Arms UDP-9 9mm PDW

Angstadt Arms has just released details on their UDP-9 9mm PDW which is an AR-15 based, pistol caliber carbine that accepts readily available and reliable Glock magazines. They will also be releasing the receiver set used on the UDP-9 for separate purchase for those who want to build their own PDW.


I am particularly interested in the UDP-9 as a Glock shooter. Glock magazines are a great choice for pistol caliber carbine since they are inexpensive, readily available, and they are offered in a number of different capacities up to 33 rounds. The UDP-9’s lower receiver is built from the ground up to accept Glock magazines so there is no need to worry about adapter blocks. Angstadt Arms is not the first to create a lower receiver like this but they are doing the concept justice.

The UDP-9 will come with a number of features befitting it’s intended role. The 1 in 10″ twist is kept to a short 5″ inches so that, even with a suppressor installed, it is a relatively compact package. The B5 Systems/UCWRG pistol grip is a great choice for a compact weapon like this due to its more vertical grip angle. The UDP-9 will ship with a Sig SBX Brace so you can take it to range right away and start using it before deciding if you want to go through the NFA process.


It looks like a well thought out package. Here are some additional specs:

  • 7075-T6 billet aluminum lower and upper receiver with a matte black hard-coat anodized finish
  • Flared magwell for faster reloads, integrated, oversized trigger guard and a threaded bolt catch screw
  • Last round bolt hold open on an empty magazine
  • Slick side upper receiver with appropriately sized ejection port and no froward assist or dust cover
  • 9mm bolt assembly for use with a standard AR-15 hammer. Compatible with both GLOCK and Colt 9mm AR-15’s
  • 5” 9mm barrel in chrome moly with a 1/10 twist and a black phosphate finish
  • Sig Sauer SBX Pistol Stabilizing Brace
  • B5 Systems pistol grip
  • ODIN Works 5.5” free float keymod hand guard with continuous top picatinny rail and mounting positions at 3, 6, and 9 o’clock.
  • Weight: Sub 5lbs
  • Length: 21″
  • MSRP: $1,095 – $1,295 depending on model
