I recently purchased an M1A Scout Squad, thinking of participating in the Service Rifle matches.
Gloating over my new battle rifle, I glanced through the regulations concerning Service Rifle matches - and discovered that my Scout Squad was not kosher!
It was too short for the required Over-All Length (OAL) and on top of that, muzzle-brakes are not allowed in Service Rifle matches.
Seems like if I had a regular M1A flash-hider, and a 2" piece of steel tubing with the proper female threads on one end, and male threads on the other, I could legalize my Scout Squad for the Service Rifle matches.
Does anybody know where I could find the piece of tubing? - I have found several sources that carry the flash-hiders.
If someone were to market the barrel-extension tubing with a flash-hider already mounted on it, I bet that they would sell a lot of them to Scout Squad owners.
