Newbie's FYI Research
Saw that similar model of the Mauser L96 at http://www.pyramydair.com/cgi-bin/mo...?model_id=1488
and it is said to be made by UTG.
To NDAS you should check out www.airsoftretreat.com/reviews/
for the JG Bar-10 and they also reviewed both UTG and AGM versions of the L96. With the teflon mod and shortening of the air brake for JG Bar-10, the reviewer got close to 500fps for a stock rifle.
