So I decieded to make a brass deflector

[MrBoxx]

If noise is an issue, lay a strip of self-stick soft-side Velcro on the inside of the shield. That should cushion the noise of the casings hitting the shield quite well. It's available almost everywhere, for pretty cheap, so if it ever wears out from repeated hits, just peel it off and stick a new strip on.

Just a thought.

this seems like something that could be injection molded plastic, and a low profile spring tab mechanism could hold it down.

could this also potentially deflect sound from the chamber?

could also be rubber all one piece so it bends securely to fit on the rail (think rail cover) and the slotted idea would work nicely, or even a clear window (since the rubber could provide the tension to hold it in place).

I say make it out of Carbon Fiber (the attachment can be machined mil spec aluminum). Pre-Preg carbon could be laid out on a long mold to get a continious piece from which many pieces can be cut out, not sure about water jetting CF though.

Carbon Fiber would look cool. Using a waterjet to cut it could be a problem though, as it may be difficult to clean up the edges after cutting it out.

Great idea!

It could be injection molded, but the cost of having those molds made would be extremely costly. I would have to be able to guarantee that I could sell a large quantity of these quickly to recover cost of tooling.

I highly doubt it will deflect any noise from the chamber.

I checked out some vid's on youtube and apparently you can WaterJet CF no problemo

You could outsource the metal component to a manufacturer (already have one in mind) and the Carbon, you would need to make a long mold so that long sections could be
pre-preg and cured and then water jetted out of the master piece, with grooves like you section design.

All great ideas but TC accessories already has them for $19.95 thumb screw and all if you really need one.....Projected price of 30-50 is going to be a death blow.....best regards Plum

That is a viable option. In my original design I had made a top mounted brass deflector. But decided to do a side mount, due to majority of owners having an optic of some type mounted in the general area above the ejection port. Most owners still have the stock fore end, so to me it seemed logical to go with a side mount instead of trying to design a top mount to work around all of the various optics everyone is running.

I agree with your assessment. A local shooter has one of the TCs on his AR and we tried it out on my 15-22. Worked, but not with the scope and riser on the upper.

I hate to harp on price but anything much over $20 will be a slow seller.

 

[SimpleWeaponSolutions]

Believe me, I know price is going to be a major factor in this. Hopefully I have estimated this high. Once I have a bit more feed back on this I will start to shop around with various machine shops to get a better idea on the cost.

One of the last things I need to do, is find my chamber flag that came with my rifle so I can see if it fits with out issue with the brass deflector installed. I have ran around the last couple of days trying to buy one, but to no avail.

 

[Majorlk]

You have my sympathy!

 

[Juvicator]

Long term if it is a huge seller I would go with a single piece injection molded. Maybe make the two 45s a big bigger so it slide on the rail with a small set screw to sinch it up tight.

 

[w0ady]

i have a couple chamber flags from one of the local ranges if you want me to send one.

An injection molded part would be the ideal cost solution. It will be on of the thing I am going to be looking at while shopping around.

That would be great. I am bought to order several types of chamber flags from Brownells to get a wider scope of testing with them. PM inbound.

 

[Majorlk]

FWIW, my chamber flags are all pieces of 3/8" wooden dowel painted fluorescent orange.

To make this a viable, profitable enterprize you have to keep it very reasonably priced, easily manufactured, and simple. As soon as you add slots, holes, springs, screws etc etc...costs increase etc....and it gets over priced in conjunction with manufacture and competor price. What you need here is a simple snap on snap off side rail deflector devise devise, most likly plastic composite, although some thin spring steel materials can actually be press fabricated much cheaper than injection molded plastic.....Cost needs to be in the $2.00 area or less and sell for no more than $8.00...Keep in mind you are selling a product that is not really needed by hardly anyone, and is a very limited market.....you need to entice sales because it will work, and it is very REASONABLY PRICED.....best regards Plum

I am in agreement with Plumbago. I have zero experience in machining and manufacturing, but I make the following observation vis a vis 15-22 accessories.

There seems to be a mentality that $50 is the target price, because that is what 15-22 owners will pay for add-ons, irrespective of the complexity of the device. If one reads through the various threads one will find that price (actual or projected) for the ambi safety, the speed loader, the brass deflector and probably others, all use $50 as the target.

The safety selector on my rifle broke, so I went for Roger's product and am satisfied with it. In it's present form, I would not spend $50 for the speed loader and absolutely would not spend that much for a brass deflector. The "it will cost $50, no matter what it is" mentality needs to go away.

 

[SimpleWeaponSolutions]

Cost will be the final deciding factor in whether this project continues to move forward. Right now have the part injection molded is not an option due to initial costs. I am waiting on a few quotes to come in from shops that make parts for picatinny rail already. So that should eliminate the cost of having a custom tool made to cut the mounting slot for the picatinny rail.


Today I went to the range to do some more testing, this time with the S&W mags. In the middle of the first mag I had a spent shell stick between the bolt and the inside of the deflector. Other than that, the next 10 mags had zero issues. I was going to get some video of it in action but left the battery for my camera in the wall charger at home.

 

[Majorlk]

Just had a thought ...

Instead of something that fastens to the rail, how about something one-piece that is attached to the space between the side and top rails. True, it would mean two small screws and not be instant on, instant off, but that would eliminate a rail clamp of some kind.

I may play around with that idea myself over the weekend.

How would it attach?

Like something that spread apart and grabbed onto the outside edges of the rail?

Just curious.

It would be cool to have a rubber grommet that pushed into the first hole on the handguard. That would be cheap and fast.

two small screws into the rail.

Another possibility, but more complicated.

Yet another mounting possibility, but again, more complicated.

 

[Majorlk]

This, without the slots. It just screws to the space between the top and side rails. Or even screws into the side rail itself. No need for any fancy rail attachment.

 

[w0ady]

how about something that attaches like a ladder rail cover? i dont see this part needing to be all that heavy.

 

[w0ady]

any update jon?

i have a nice burn on my cheek from yesterday. i space my glasses a bit to prevent fogging and i guess a spent casing somehow got in there. i didnt pay attention til the burning started doh. id definitely be up for testing any prototype if you need that as well.

Ouch!

 

[w0ady]

nothing major, its already peeled. only took a pic cause my gf was at a concert and didnt want her to get upset lol. actually have another small burn near my bicep from another casing. who says the range is boring?

 

[SimpleWeaponSolutions]

w0ady, ouch!

These will be going into production in the next week or two. It looks like I will be able to keep the price low. I still have to work out a few details before I have a final price.

This is what I have come up with for the final design.

This is the direct bolt on configuration.

This is the quick release configuration.

 

[w0ady]

sweet! i call dibs lol.

Bolt onto what?

 

[w0ady]

side rail.

 

[spider2k]

interested just for the aesthetic appeal. depends on the pricepoint though.

personally id suggest a knurled knob instead of the keyring. or at least a way to choose.

 

[LS1 KLR]

Definitely interested!
