Re: AUG vs MSAR
I have two MSARs: an STG-556 Gen.3 and Gen.4. I've got about 2500 rounds through one and the second is a safe queen but has been fired a bit. Never a problem with either. The rifle handles very quickly, is lightweight, well balanced, and "aims itself" for lack of a better way of putting it. I installed a trigger mod called the Neu-Trigger that adds a small metal 'shim' to the trigger to eliminate the plastic-on-plastic rub of the hammer and sear which brought the trigger to a respectable 4.5 lbs. pull. I'm actually planning on using one for 3-Gun matches.
I have an acquaintence who I share a shooting range corporate membership with who has a Steyr AUG A2 and we have exchanged rifles several times. They are very VERY similar. Steyr magazines can be modified with a dremel tool and 5 minutes of time to fit the MSAR and the MSAR mags fit the Steyr with no modification. Trigger packs are interchangable. Otherwise, the rifles are not interchangable parts-wise. They feel the same and fire the same to me and to my AUG owning acquaintence.
Ultimately, I bought my MSAR because I always wanted a Steyr AUG. I'm glad I bought the MSAR, I enjoy the rifle, and do not regret the purchase.
As for that 20" barrel: I have a spare, brand new 16" barrel and would be interested in a straight-up trade for a 20" if you're so inclined.
