| Click on the pics for bigger views. This page is going to show you how to put a new hop up o ring on a sun project M40a1 XB. |
| Unscrew the 2 screws that hold the stock on. the one by the mag well and the one on the trigger guard. have it look like the pic on the right. |
| Take off the Trigger mech and the sear so you can take the cylinder out of the gun. |
| Take off the brass part that the stock is screwed into and take the mag well parts off, then where that allen wrench is un screw that.. but dont lose that part. Slide the whole part out towards the back of the gun. |
| Unscrew that little screw that the allen wrench is on. You dont need to take it out all the way.. Just unscrew it until the barrel comes off the chamber. Then Pull the barrel out. |
| The middle O ring in this picture is the HOP UP O Ring. Replace that with a smaller o ring and your hop up will be better. Not the best, but a lot better.. Then reasemble the gun. and test fire.. it should be a ton more better than before.. |
| Thats my Sun Project M40A1 XB Sniper rifle.. It has a K2 Stainless Steel Cylinder and a PDI 340% Spring inside her.. She packs a mean punch |
