I recently modified my Long Strike. Before modding it shot about 3 feet ANGLED so I removed the air restictor, upgraded the air seal, and strecht out my beat to crap spring. I also painted it which I will show and discuss ind another topic. But getting to the problem, without the clip in it and just sticking the dart in the "chamber", I gett about 30 feet flat, with the clip, I get about 6 feet flat. Does anyone know what the problem is?

Update: I read your sudgestions and opened the blaster, it turns out the dart tooth was stuck down.

First, don't post a separate thread for your paint job. Put it in the mods and PJ thread. Second, If you upgraded your seal, there may be too much friction for the stock spring. Also, stretching your springs weakens it over time. Did you relube the o-ring when you replaced the plunger tube?

This addresses the overall poor ranges of the Longstrike, but not the discrepancy between single-loading and clip fed ranges. Could the dart tooth be malfunctioning, and not pushing the dart into the breech? Did you remove it, thinking it was a lock?

Again, you have the physical blaster, and therefore a better vantage point than most of us here to tackle your precise problem.

Those horrible ranges PRE-modding speaks to something seriously out of whack. My money's on a faulty dart tooth, I would look at the internals pictures directory to see what the dart tooth is supposed to look like, then go from there.

Have you checked the seal on your plunger rod? The washer could be cracked. I also want to point out that streching your spring will not work at all. After one full compression it will return to its original shape. If you want it to hold its shape, then you must heat it with a torch, then cool it in water.

And if you screw up the heat treatment, the spring will become brittle and explode in your face.

Also incorrect is the notion that the spring will return back to the original state after one full compression... it won't.

Yes, I relubed ththe o-ring, the spring has stayed streched, and the reason I will be putting the paint job in another thread is that I have a whole new color scheem spanning mutiple blasters and this is a problem with a specifec blaster.

He's not joking. If you start a topic just for your painted blasters, Langley won't be happy.

Did you upgrade your seal? if you upgraded it too much, it will push the o-ring against the walls of the plunger tube, and no amount of lube will decrease the friction from overcontact.

And lastly, did you check the dart tooth? It sounds like the problem may be in the dart tooth.

Alright, it probably won't return after just one compression, but it will shrink back with a small amount of use.

Don't you guys study Hook's Law and Young's Modulus and the effects of stretching metals until they fail.

Once a metal is stretched past its elastic limit, the linearity is lost and it will not return back to its original length.

And according to the equations, the spring is made weaker if you stretch it beyond its elastic limit.

In summary, stretching the spring is a false economy

Hammy: You are now my favourite FNG.

Back to the mod - I'm almost positive it's the dart tooth. That's the part that keeps the dart in the magazine while the bolt slides forward, effectively forcing it into the bolt (I say effectively because the dart is stationary, so pedants will pee.)

Remove the faux barrel, pull the bolt all the way back, and look down the barrel. If you see a small piece of plastic in front of the magazine rising about halfway into the barrel, then the dart tooth is in place. If you see see clear back to the plunger, then the dart tooth is not rising properly.
