Interfor AR15 STUBBY - 5,56 Nato pistol with SBA3 brace

This time we rebuilt an old timer. A clone of the famous Olympic Arms SA15 "Stubby". 

In the '90s this gun was considered so revolutionary because it could work with 7.5" barrels. Adjustable gas block had not been invented at the time and the manufacturer invented a pig tails tube which was basically a full length tube which turned around the barrel to keep gas level down and control overgassing. The original gun was not very reliable (we discovered later that the tube tended to come off under heavy use) but was so revolutionary that it was adopted by (at the time private) escort detail of Silvio Berlusconi, not yet a politica figure.

Italian cops like me watched at the gun with envy as our Beretta M12 SMGs seemed little toys in comparison to that gun.
