ok i got a rifle i made with a 2ft long peice of 2inch pipe as the air chamber. i also have some different size barrels that go from 2ft long to 3.5ft long.It has an inline formation for the extra power. problem is that the gun is 6ft long. how should i shorten it?

shorten air chamber

shorten barrels

under/over?

post too short.............................

REEDIT: nevermind

Ever heard of a sawed-off?

yes but id like to keep accuracy

As stated above, is it an over/under design, that means that the barrel is on top of the chamber. God forbid under-overs becoming popular

Too bad accurately mimicking the ergonomics of a traditional rifle are far from simple using standard plumbing parts....

You can come pretty close. Below is a pic I just took of a gun I've got 90% finished (really need to get off my arse and finish it!). Nothing but off the shelf parts there and the ergonomics are very close to a normal rifle.

(And despite being made from steel - not PVC - it's still pretty easy to handle. Why? Because ergonomics were considered from the ground up. It handles pretty much like a normal rifle.)

Well, almost



Looks like it can handle quite a bit of pressure...

this is how I made a rifle style stock out of pvc


@D_Hall: though the weight seams fairly balanced on your shoulder the barrel placement on that gun looks pretty high so the lack of muzzle weight and high barrel placement looks like you'll have a good bit of muzzle jump on that gun

The man has a point, perhaps it ought to be inverted so the barrel is resting on your shoulder?

Three words: moment of inertia.

Not to say that there won't be muzzle jump. Rather, to say that I think it will be managable due to the moment of inertia that a long, heavy gun results in.

Time will tell.

No it won't, action will tell! Go finish it!


Trying to encourage you as you have the common problem of "(really need to get off my arse and finish it!)"

Going for rifle ergonomics is hardly difficult.

If you can fudge together some form of pistol grip...

... then you can get something which handles like it's a large rifle (bipod and scope optional).

@ Marffy: Don't fool yourself into thinking that barrel length has all that much to do with accuracy. Yes, firearms with longer barrels are generally more accurate, but don't mistake that for cause and effect.

Long range rifles both need the accuracy to hit at long range (as targets "appear" smaller), and more velocity (to reduce time to target, and to still have enough energy left after the drag).
It's this latter part which is linked to the barrel length, because longer barrels will yield higher muzzle velocities. The higher accuracy is simply to do with the fact that these weapons are built to higher standards (and usually use better quality ammunition).

So, yes, the two often go together, but neither one is the (direct) result of the other.

Sh*t Rag! update the page on your HEAL! :thumbright: We never saw any pics with the add ons

Gotta finish Vera first!

(speaking of which, most of Vera's control circuits got wired up this week)
