This gun is the quietest I've heard. Especially when your talking stock barrel(which is 13" with a great muzzle break).The Sub-Zero Six Stages Expansion Chamber is great not only for CO2 use but also for a very comfortable foregrip. The stock is so comfortable that you can lay back in bushes or in a bunker and pick people off. The 45 Grip,trigger & trigger gaurd are so comfortable I never want to even think of replacing them.The designer case,elbow(made like a VL-BOW in purple) and barrel plug(AVALON in purple) included are fantastic. The accuracy is excellent, the wind throws balls off, but the barrel keeps them on or near the target regardless of the wind. More extras in the case with the gun than I even bothered to hope for. Handles and looks like a dream.It's apparently fully Spyder compatible.
Mine had a stripped but easily replacable screw. Avalon is sending the replacement free of charge. It ain't ugly like most other guns, RATS!!! It doesn't work with small CO2 tanks, 20 Oz. is recommended in the manual. With a 20 Oz. though you won't be disappointed. It's not loud either, double RATS!!!
It performs so great with just stock parts that I would only replace the barrel if you want to add other colors to match camoflage or team colors. It's worth twice what it costs. Easily better than all competition, if you have a Spyder, visit diamondgt.com and order the stock for this gun if you love the look and feel of it like I do. If you replace the bolt, get the most upgraded version of the Spyder Force __ Cycone Bolts. I would recommend it to everyone over any other gun. I may be a bit bias, I LOVE THIS GUN!
