The m2 rail feels great with a 6US xxx rifle.   Nicest final finish of all the AUGs I've had/have over the last 35+ years of AUG ownership craziness.

The M2 Rail as adds about 3oz to the rifle. (front grip removed)


These waits are aproxomato from a cheep scale ;

6.5 oz.   AUG A3 SA Rail  - removed from 6usSAxxx rifle
4   oz.    AUG A3 SA Front Grip Assy.  - removed from 6usSAxxx rifle
----------------
10.5 oz Total A3 SA Rail and grip assemblies.


7.3 oz    AUG M2 Rail
6.2 oz.   AUG M2 Forearm
------------
13.5 oz   Total M2 Rail

My mispellin and gramur are sidered a(n)  enhancemunt.
