Hello, fellow nerfers! I know that you're all quite tired of concept threads, however, I simply do not have access to the proper tools required at the moment.

Anyway, my concept was one that would work best with springers, being that when you prime the action of the blaster, you also pull back a spring-loaded breech. The blaster would function as such:

(1) You prime the blaster, hence also priming the spring loaded breech.

(2) You leave the priming handle in the rear position (like you do with a snap or +bow).

(3) You pull the trigger, which (a) slams the breech over the dart, sealing it with the barrel, and (B) fires the blaster.

(4) Rinse and repeat.

Basically, the idea is to shorten the length of time between firing rounds when using a springer that is N-strike magazine capable. You have to admit, manually-operated breeches take time to reload.

Sorry for the crudeness of my MS Paint drawing. As you can see, my idea involves a two-stage trigger. The only problem I can see with it is that this is a very long trigger pull.

Any suggestions as to how to get this idea off of the ground? Also, is it even worth attempting? I hope that someone finds this valuable information and is able to make it successfully.

I don't think this would work... You could do it and prove me wrong though.

It could work if you have a really good seal and the AR intact in the blaster, so that when the dart contacts the AR, it releases the built up preasure.

This is one of those high work - low reward projects. It is well thought out, but it's somewhat useless, no offense.

You probably save 3 or 4 tenths of a second with this complicated thing. Pushing a priming rod forward is a simple task that requires no muscle or effort.

I think one issue that'd give you trouble would be your bolt slamming forward- that looks liable to be a source of jamming. You can only draw darts from a magazine so fast before you have problems, that was one of the limitations of increasing the battery power on the stampede. As for open bolt designs, it looks like you'd have additional wear from the slamming process.

This looks like a nice concept, but slamming has some inherent limitations.

Here's a problem with that idea: because the bolt is slamming forward to close the breech you're putting major pressure on the front of the plunger tube and decreasing plunger tube volume as well. You could end up killing your ranges as well as your plunder tube when that shatters and sends the dart, bolt, and plunder at the target.

with the Nstrike breech being notoriously fragile already (especially the plunger tube ) i think this would be a bad idea. Why don't you rig it like a maverick so that it uses a weak torsion spring and pulls the breach, slower, but less expensive in blasters B)

I have a real bad crisis here, you know those shells that come with the doubleshot? i hammered one of those down the extension barrel of the recon and it looks pretty cool... but the problem is, it blocks the bullet!

Wouldn't the plunger go forward at the same time as the breech? That means that there will be air coming out of the plunger tube before the breech even seals the dart...which means that there will most likely be air loss, once the dart is propelled into the front part of the breech, and while the breech is still closing (possibly).

Absolutely Horrible picture quality... but you get it. Thats a longshot bolt. Right before where i cut it, there was a hole that you would want to fill if doing an AR Removal. I did not plug that hole, and here's what started happening to me. I had all locks removed. If there was ONE dart left in the clip, And i only pulled the bolt back, and fired, It would slam forward... and Shoot!

That might help a little.

Wouldn't this just be making a homemade longshot plunger tube assembly. It looks almost identical from the picture accept for the catch being closer to the PT. Best of luck if you can make it. Also, it also looks mighty similar to airsoft springers so look at those if you need ideas. If the PT and the breech slam forward at the same time than there won't be enough volume for air to build in which launches the dart.

No, we're not tired of them, because they're simply not allowed.
