My question is where do you plan on stocking the shotgun-pump-grip?
The Maverick is sitting right where that's gone in most other mods.

I'm not sure that the draw-lengths are anywhere near close enough, but it would be cool if the same "pump" would cock both guns.

Good luck!

(Also: Props on the TF paint scheme idea.)

I didn't use a specific spring (BBB, NF, etc.), as I don't have a ready supply of any of those. Instead, I just pick up an bunch of springs from the hardware store, and use the strongest one that will fit.

I believe this one is rated around 165 N/m. I've used a similar spring before in a LS spring addition, and achieved typical results, if that gives you an idea of how strong this spring is.

Just another thought, despite the original idea being dead:

What about cutting a Longshot down to pistol size?
Would that not essentially capture what you were trying to do, with slightly less work because you've got all the clip-feeding parts in place?

(I wouldn't attempt it... but it's an idea!)

Precisionnerfer-

I think this is finally starting to make sense to me, that they would balance it all out that way between the rifle-type weapon and the pistol-type weapon. It explains why barrel extensions work, as well as the slightly more intuitive spring replacements.

Thanks for explaining this.
(Someone should sticky your post.)

First off, I'm not sure some of the assumptions being put forth here are true.
A "more compressed" spring is not better than a "partially compressed" spring if it's the same spring. You're going to get about three inches of displacement for any spring, just because that's how long the "ARMED" thing is.

Hooke's law tells us that Force = SpringConstant * Displacement.

As I said before, we know Displacement is always three inches. So if you take the original setup, with that super-long spring that extends to the rear, and assign the spring a constant of K, then your force is 3K.

I believe it was suggested to use a shorter spring that fully compresses. However, this is still only going to have three inches of compression, so unless its spring constant is greater than K, it will have the EXACT same effect. Seeing as how the OP was using the AR-15 spring, I doubt anyone was suggesting sticking anything much stronger in there.

I guess what I'm trying to say is that "compression" yields a linear increase in force. Compressing it the first inch gets just as big of a jump in force as the last inch does.

So the original setup really can't be improved on much.
That said, I did the same mod a little differently.


The first thing I did was fashion the above items. First, crack open that middle piece of the stock. Find a wooden shim and cut/file it down in the appropriate way such that it creates a "base" perpendicular to the direction of the compression of the spring. Glue the spring to it. In order to ensure the spring didn't mess up the plastic of the ARMED piece, I glued a washer to the other end of the spring.

The second piece is created by getting your pipe cut to a length such that it is flush with the black square end of the gun, AND the middle piece of the stock when the gun is connected to the stock. Finally, bore a hole (I used a dremel tool) in the middle stock piece with the same inner diameter as the tube. I used a sparing amount of hot glue to affix the tube to one half of the stock piece.

Connected, they appear as so:


Another angle, you can see the washer here:


Fully assembled:


Attached to the gun:


I'm sure the spring I used wasn't quite as strong as the AR-15 spring. In fact, I had to the clip it a little, because even fully compressed it was physically too large, and this made the cocking of the Recon impossible. However, even though I shortened it, I've seen noticeable range increases, and the gun can still be cocked almost as quickly as it could before.

I would be wary of sticking anything much stronger in there, as the mechanism that holds the stock on is what takes the entirety of the strain of the spring (at least it does the way I crafted it). I worry that anything much stronger will just snap the stock off, perhaps in an irreparable way.

Thoughts?
