Did you buy it new? Did you check barrel retention bolt torque(assuming signts were tight)? Did you try any other ammo? What gas setting are you running on? If it's "climibing", you may need to turn down the gas. I've had several examples with comps that were loud as worlds colliding but they didn't recoil for anything. I'd wager stock(brace?) position isn't going to help much. Also of note, depending on which back end option you're using, the original position of the top/buffer tube on RA stocks were in line with the bore.
Which upper are you running? If you've got a light profile barrel and a keymod upper, you're not going to be able to lighten up the front end much. It's a long stroke piston(even the type 2 still has a lot of stuff up front), it's going to be heavier than a DI up front.
