raincover
 
2 Attachment(s)
I will be making raincover tips for barrel systems. This will be a Monocore design. outer shell will be aluminum anodized black and core will be black delrin.

The threaded end can be anything you like as long as you have a mating part to use as a Gage.

I have been approved for preorder on these. This is the timeline of the job.
The preorder will be open until 12-14
I may start earlier depending on orders but will not change the date.

After the preorder lead time will be 3-6 week as I will be doing most all the work at home on the lathe. This combined with custom barrel threading will make it kind of slow going.

Now on to the specifics of the cover.
Core will be 2" delrin 6" long
The housing will be 2-1/4 dia. alum and length will be 6.5" long.
Overall length will vary a bit depending on thread option.
Price $85 plus shipping
You may get them in raw if you like to have done with your own finish
Any questions feel free to ask

Here is a core rendering

I'm interested. I'd just like to see/hear a prototype.

Ill take one if you can thread it to fit a lapco/tiberius barrel tip thread (7/8-20). Let me know if you need a barrel or tip to work from, and let me know when/how to pay.

If you can ship one overhere, Iam in.

Same here. Concept is nice, but preorder money comes after I see a proven prototype. Will be watching...

Will there be a ported center tube in the design?

jcurt455 11-29-2012 01:13 PM

No ported center tube.

jcurt can you explain how the design is meant to dampen the um... rain? I'm in as long as the prototype does what it's suppose to.

I have made a similar one but I was smaller in just about every way. I will say I worked ok better on a lower pressure gun.

The basic idea is simple. When you fire your marker there is gas behind the ball. Gas or air expands and when the ball exits there is xxx amount of pressure. With ported barrels the gas escapes from the barrel through ports giving a lesser sound signature from the muzzle end.

Now as the ball enter the first chamber of the core gas or air will expand loosing pressure. Into the next chamber same thing and so on through the last. Now if we can get an engineering wiz to help out I'm sure it can be calculated what kind of pressure drops we may be looking at.

I'm very interested, would love one to put on my longbow barrel. Any chance of a video or sound comparison? Looks like an interesting design!
