  3. Worth every penny 5 Star Review

    This stock is amazing, I couldn't ask for better.
    I put it on my Custom G&P MK18 I built and It's very durable. The EPS has sooo much battery storage. I've tested it out in a few games and it is just beautiful. Very easy to swap out batteries which is a plus, you don't want to be spending 5 minutes to change out the battery. With this stock it took me a minute at most. Overall I rate this 5 stars and would buy it for every build or new gun I buy.
