    Hello all, I am hoping to get a Madbull JP hand guard with outer barrels. I'm a little confused because I want to get the 24 inch outer barrel with the JP hand guard. How much millimeters will that be. This is for my dmr and also what other preparations should I make for it....cylinder,spring,etc. Lastly, would this be a good by, honest opinions are appreciated. Thanks!!

    When you decide on a barrel length be sure to have the cylinder volume and barrel volume balanced. It can greatly reduce accuracy if it is improper.
