    Very good BUT...

    I received this gun a few days ago, and i have really enjoyed it , i have thoroughly weathered it and made it look much more authentic, however they shipped it with a spray painted orange tip. Why would you spray paint it :(,i have been trying to sand off the paint and refinish it for a few days now. :(:(:(, surely there are better ways to put an orange tip on.

    I could not be happier with this purchase. The gun looks absolutely beautiful and shipping was fairly quick considering the distance it traveled. I would Definitely recommend this gun and Swit Airsoft.

    Excellent Quality

    This gun has incredible build quality and the upgrades done are just as good, its very satisfying to shoot and I find it has great performance with 0.4 gram. I recommend this gun to anyone interested and I recommend Swit airsoft as a company.
