AAA SAP – Another Offspring of Charles St. George’s Leader T2

AAA-SAP_22auction_002

Aftermath Gun Club has posted images of the Leader T2-derived AAA SAP pistol on its firearms identification site ID.Gun.FM. The Leader T2 was not a commercial success, resulting in the dissolution of Charles St. George’s company Armtech Pty Ltd in 1983. The patents were subsequently sold off to the Australian Automatic Arms company (AAA) who produced Leader derivatives in 16.25″, 10.5″ carbine, and a 10.5″ pistol variant. The latter, called the SAP, was imported to the United States for a brief time.

All AAA weapons lack the carry handle of the Leader T2. Weirdly, the AAA gunsappear to have different bolt configurations. The original Leader T2 has the characteristic triangular bolt, while the AAA Sporting Purpose rifle has a classic Stoner-Johnson type bolt:

However, the pistol variant SAP has a strange hybrid bolt configuration:

The AAA SAP bolt compared to the Leader T2’s bolt. The SAP has an odd triangular bolt configuration with two elliptical feed lugs. The bolt face is also left in the white, for an unknown reason. Image soure: id.gun.fm

 

A handy photo of the SAP’s bolt carrier compare to three other weapons’ illustrates some of the unique features of the Leader and its derivatives:

Bolt carriers compared. Note the reversed cam pin rotation direction of the two Leader designs. Also note the chromed bolt of the Sterling AR-180 and the additional underlug of the SCAR 16S – both reliability enhancing features. Image source: id.gun.fm

Three years ago, Forgotten Weapons posted an interview with Charles St. George, designer of the Leader T2 (and by extension the AAA SAP):

    The MPAR looks identical to this gun– did Masterpiece Arms just buy up the design, or just copy it? Not that it doesn’t seem like a copy in many regards in the first place…

    • Dracon1201

      Thats because the MPAR is the Leader T2, but “updated”. Look at InrangeTV and Forgotten Weapons for more info.

    • They didn’t buy it, but are on good terms with Charles and talking about future projects.

  • RemovKebabs

    That guy in the first video is a giant stereotype of himself.

    I owned AA SAP…..the magazine fell out every-time I pulled the trigger.

    • I have the opposite problem, the magwell in mine is a bit tight.

  • toms

    The leader was tested and almost adopted by Australia but lost to the AUG. The rest is history

  • mechamaster

    A bit troublesome that MPAR

  • Anon. E Maus

    Oh how I love the brilliantly simplistic design of the T2, it’s like the logical progression of the AR-18. Really hope MPA works out the kinks on their model.

  • Tassiebush

    I’ve often wondered why a pump action carbine version of this wasn’t tried in Australia after the semi auto ban? There’d be a market!

  • Graham2

    What an superbly compact design. The AR15 has such a massive buffer and spring in comparison.
