Well I'm not answering your question until your post is atleast readable.

Wow, you're not very long then. How do you go up stairs?

You know, it doesn't have to be a cut down BBB spring that you use. People mention that exact thing so much I get the impression that there are tons of kids running out and dropping twenty bucks on a BBB at Target just to cannibalize the spring. Lots of springs work, just keep an eye out. Plus, all those other springs probably don't cost a tenth of what the BBB would run you.

Only 3 possible causes to your problem
1) You added the spring and it's too long for the plunger to advance far enough back to engage the trigger plate completely.
2) You need to replace the spring on the trigger plate so that it can hold the extra tension when the plunger is primed
3) You didn't reassemble the gun properly

I'm not using a BBB spring, but I still have to replace the trigger plate spring and make sure I cut my additional spring to the right length.

What spring are you using Captainslug?

[CaptainSlug]

I used a trimmed section of this: http://www.bravocomp.....g carbine.htm

A full BBB + LS spring will work, you didn't reassemble right.

[NerfMonkey]

An LS with a full-length 3B spring and the stock spring will not work, not for me. I reassembled mine perfectly and it wouldn't catch. It depends on the gun apparently.

[General Cole]

No it is just really hard to cock, amazingly hard to cock, now all I need is some barrell material and I am set. The trick about the BBB + LS is that if it doesn't lock in place initially pull back harder again, should take you one or two shots, but it will work.

[CaptainSlug]

Brute force is not a good solution to this problem. If you cannot easily prime the gun with your additional spring installed you need to either lengthen the plunger rod by replacing the plunger head, or you need to trim your spring a little.

The limit on how much you can lengthen the plunger rod is affected by the ability of the catch on the rear of the plunger still being able to depress the bolt-lock when the plunger is in the forward position. Thankfully the dart-lock isn't too dimensionally strict so the tolerance on the plunger rod length is around 3/16".

Replacing the plunger head in both of my guns made a HUGE difference in the reliability of the weapon cycling. And as a notable secondary benefit I also got a much better plunger seal.
