#SIG P320 PELLET GUN JAM UPGRADE#

You can also upgrade the large slide spring because your gun will have more kick now. Tighten down tight but not superman tight.ġ1.) Re assemble slide. When screwing in the back of the valve go slow and make sure the oring sets correctly. Now when installing the nylon oring apply just a little bit of greese on the oring. Moly is best.

Throughly.ĩ.) Re assemble valve housing to gun. I would replace any rubber orings at this time but it's not necessary.ġ0.) Reinsert valve saft. But 2mm larger hole should be great.Ĩ.) Clean valve housing with acetone. The lowest acetone percent female nail polish cleaner works great.ħ.) On the valve housing there will be the c02 inlet. Be careful as you can go too much but you can get away with about a mm larger hole.Ħ.) Throughly clean shaft with acetone. You will be drilling 2 places on the valve.ĥ.) Using a drill bit the same size as the oblong hole on the side of the shaft put the drill bit in the hole and hone this out larger. Be carefully as its spring loaded, not alot but it will unspring when you get it out.Ĥ.) Pull the spring and valve shaft out of the valve.

#SIG P320 PELLET GUN JAM DRIVER#

Back of valve should be exposed.ģ.) Using a large flat head screw driver remove back of valve like a normal bolt. If anybody has torn down a C02 MCX, and has any tips please let me know.ġ.) Remove c02 cover and c02 if one is in it.Ģ.) Remove retaining pin by trigger and slide.

#SIG P320 PELLET GUN JAM MOD#

My next challenge will be to do the same mod to my MCX, however from research I believe this is a bit tough to disassemble. So by keeping the valve restricted a bit they can keep the power in the 350fps range, making it legal everywhere. The two main problems most people have with the gun. Honestly I think Sig could have shipped out the gun from the factory this way but this gun would be illegal in any areas where a gun over 500fps is considered a firearm. Just a bit of work and this is now a very powerful gun that is pin point accurate. The barrel locks up when fired but this can change where the sights were pointed. The gun its self is accurate, but with this problem it SEEMS inaccurate. Its not bad, as it looks to be designed this way and it seals when the gun fires but it does cause the gun to seem very inaccurate.

Lastly the barrel on these is loose from the factory. Well it does on this gun because with the added power of the valve work, a stronger spring keeps the valve open longer and all the semi auto actions work correctly. I know this doesn't improve power, and in some cause can actually take power from the gun.

#SIG P320 PELLET GUN JAM MODS#

Other mods I have done are - vent holes to help with C02 freeze up on fast firing, and venting for over heating of the C02 causing the hammer to not be able to push the valve in. Stiffened up the blow back spring. But its completely free and only requires basic tools, a hand drill, with a small (1/8in) drill bit and some attention to detail. If any body is interested in this mod please let me know and I can give you step by step instructions as you can mess the nylon o-ring up if you disassemble the valve wrong. It is just as powerful if not more then my MCX. However it is well worth the cost for this. After the mod I am getting well over 500fps from my hand gun. The valve is very easy to disassemble and bore out. Next I tore the gun down and pulled the valve apart to see what could be done here. However after many attempts to find an HPA adapter, and trying to build my own, I was at a loss. Originally I wanted to run HPA to get the consistency and power up on the gun. I am able to sink pointed pellets well over an inch into normal 2x4s. However, I do want to say that I am not responsible for any injury you my have or cause from these upgrades. This mod might work for the cyber gun or a regular p226 but I have only done the mod on my X5. This post is for anybody with a Sig Sauer P226 X5 C02 pistol.
