Today I bought a used Longshot that appears to have had its AR removed, which saved me the trouble of drilling the AR out myself. However, the blasters internals were not correctly aligned, which I fixed, and there does not appear to be any damage caused by this. The blaster now fires farther than stock and primes beautifully without the bolt/clip lock in anymore. However, I have noticed that although the blaster shoots as far as my other modified blasters, it does NOT suction load darts, it also makes much more noise padded than my other padded plungers make, almost as much as when I dry fire it (not that I do often!). I decided to plug the barrel to check the air seal, which I had only quickly checked before I put the the blaster back together. Before reassembly the air seal was not 100% but did take a good 10 seconds for the plunger to come to rest while the barrel was plugged. Now it comes to rest MUCH quicker, taking only about 3 seconds. The air seems to be escaping around the back part of the bolt, the part which is black. The air release hole is still very much sealed, but the part that is actually in the plunger does not seem to be making a good seal with the surrounding parts. The bolt does not seem to be detachable from the plunger tube, so I can't tell if this moving part has its own O-ring around it, but moving it up and down in the plunger gives me the feeling that it does not.
Has anyone else had this problem with air escaping around the back part of the bolt inside the plunger, and have a way to improve the air seal? I feel that if the seal was better I could easily be getting 10ft+ more out of this blaster! The reason I bought a Longshot in the first place was to have it outrange my reverse-plungers!
If you would like to see pictures of the part I am talking about, I will gladly snap some.
EDIT response due to FNG post limit: @jackrabbit - All moving parts and parts that make contact with a moving part have silicone lubricant. I also used spray silicone lubricant to try and get lubricant behind the black plastic piece inside of the plunger tube. Also my other plasters and ones that I have modded do have a perfect seal when under the pressure of their springs, obviously I am talking about plugging the BOLT, not the FAUX BARREL!
