Micro ARP 10mm Pistols & Uppers

10mm Micro ARP Pistols, Uppers & Kits
Micro ARP 10mm builds combine the compact size of a pistol-caliber AR platform with the impressive energy of the 10mm cartridge. Designed for shooters seeking increased power over traditional PCC calibers, these compact AR builds offer excellent performance in a maneuverable package.
The 10mm Auto cartridge has earned a strong reputation for its velocity, energy, and versatility. When paired with a Micro ARP platform, it creates a powerful firearm suitable for recreational shooting, outdoor use, home defense, and custom AR projects.

FAQ
What magazines do 10mm Micro ARPs use?
Glock-pattern 10mm magazines with a Glock-pattern pistol-caliber lower. A standard AR-15 lower with 5.56 magazines will not work.
What does Non-LRBHO mean?
The bolt does not lock back after the last round. LRBHO models lock the bolt open on an empty magazine.
Do complete Micro ARP pistols ship to an FFL?
Yes. Complete pistols are firearms and ship to your local FFL dealer. Uppers and kits without a lower receiver ship directly where state law allows.
What does "SBR ready" mean?
The rear setup accepts a stock, but adding a shoulder stock to a pistol with a short barrel changes its federal classification. Do it only in compliance with NFA and state rules.
