American Tactical 9mm Adaptor for 5.56 Lower Receiver Specifications

New from American Tactical, the AR-15 conversion adapter that will fit any standard AR-15 556/223 lower and convert it to 9mm with no required modifications to your lower or magazines!

Made from 6061-T6 Aluminum, this durable mag well adapter has a built in magazine release for your Glock mags, locks in place with your standard AR-15 magazine catch, releases the same way AR mags do and has a bolt hold open feature that locks your bolt back after the last round.

This 9mm AR adapter accepts Glock style double stacked 9mm magazines and comes with one 10 round magazine.

Plug and play and convert your lower to 9mm affordably today!

IMPORTANT! - You must install a complete 9MM AR Rifle or Pistol upper receiver onto your 5.56 / 223 / 300BLK lower receiver for this to fit and operate. Attempting to install your 9mm Adapter in a firearm without a 9mm upper receiver installed may damage the adapter or your firearm. Damage cause by improper use will void the Limited Lifetime Warranty. Attempting to fire 9mm ammunition through an upper receiver that is not a 9mm upper receiver may result in injury.

IMPORTANT - It is recommended that you use a 9mm heavy buffer. Standard AR-15 buffers may be too light to operate the 9mm upper system without malfunction.
