This guy weighs 35 grams (1-1/4 ounce).
Uses an RTP sear.
Prototype sear pin design. (No holes in the side)
AM or RTP style bodies.
RTP ASA slot.
Length and thickness based on the AM rail.

Excellent work, as always! :cheers:

Nope, no room for the slot, way too narrow. The pump milling on SS bodies can be seen on the outside of the rail.

So when are these going to be available for your loyal fans?

I'm guessing after I get it and make sure it works. LUKE has designed in a new sear axle and wants to be sure it works prior to making a run of them. This specific one also has been milled shorter than an AM/MM rail on the back end eliminating the Zlock pin. My planned use for this is to run a capped valve and external reg. Not sure if the "production" run will have the longer rear for the Z lock pin or not.

* Fixed

Honestly I really had no intention of releasing this exact rail without the z-lock. Really this was just a custom for OPBN. There were issues with the rails he sent in to machine this design out of so I saw it as an opportunity to test a new sear pin design and material reduction for less weight. He gets what he wanted and I get a chance to test a prototype. I agreed to the rail design because he was removing the factory regulator anyway. If you guys really want a rail similar to this I can do something real close but the marker would have to be disassembled to remove the valve. I can add the “pin lock hole” without removal groove. That just means you have to separate the body from the rail to get the valve out, field stripping takes a few more minutes, probably not a big deal for most of us.

Dont ask for pictures because its just a thought at his point.

BTY my real friends call me Luke. :D

It would be nice to have an ultralight rail option on the market again. I for one could care less about field stripping my valve as I've never had to do it before and with a macro line I find it incredibly easy to pull the body with an extra screw anyway.

About the middle of the page. That one is also mine ;)

OK, here is one more. It was the first to come off the mill for OPBN but the FG area didn’t work with the RTP ASA. I tossed it in the recycling box then got to thinking I could just machine the FG mount area off. This weighs exactly 1 ounce! (Just for fun and bragging rights) I do believe it is the lightest and smallest RTP rail ever made.

thats funny, but cool

i like it.

do you think it would be even lighter made from acrylic?

luke
04-22-2012, 06:04 PM
lol, it's one ounce, how much lighter do you need it? :)

If you really want to know, look up the weight specs on both materials and figure the percentage difference. ;)

luke
04-22-2012, 07:02 PM

It would be in the neighborhood of 12 grams for the rail without a foregrip mount.

The one with with the front mount or the one without? The one with should be about 6 5/16", the one without 5 3/8".

Not sure how someone would run the air though. No meat left on the rail for mounting anything. It would have to go frame bottom.

Just curious, Over the years I know there have been other super light rails made. Some similar but some of them have a issue that when clamped to a body they flex & screw up alignment of parts. How is this one?

luke
04-23-2012, 08:38 AM
These are designed to the exact wall thickness as every other rail I do. I keep it on the stronger side, way more than others I've seen. ;)

I had Luke make one from an AM/MM rail already and have not had any issues with it yet:

Granted, I have only put paint through it in my back yard, it still fires nicely. Thinking about hooking it up to my SHP reg and surprising someone the next time I go out and play...

With that said, I also am not exactly a hardcore bunker diving kind of player. Partially because I am 44yrs old, partially because I don't want to scratch my gear. lol. I don't know that you could hang a car from it or anything, but who really does that?

What is the stock weight of a AM rail? I can't figure out how impressed to be with the weight savings, ha.

OPBN
04-23-2012, 09:30 AM
First off, the newest one is made with an RTP sear, and I dont actually have a stock one of those to measure. I can say that a stock AM rail is 4.65 ozs.

This is a RTP rail, not an Automag rail as OPBN stated, I dont think a lighter one has ever been done.
The stock RTPro rails weighs 7.5 ounces.

Do you or are you gonna make an R/T length version of that rail? I may put down my dreams of finding a thrasher for that.

luke

I do plan on putting out some rails after I get feedback on the sear pin. I plan on moving away from modding AGD rails, so yea it's probable. :cool:

Well I need to get that zayan request in soon. I know there's more money in making you own rail but probably more liability too. Just something to think about, not killing ur dream.

Light.

On a serious note, if I get a chance at some point to pull apart 3-4 markers to get some sort of weight I will. The RED CF marker up above IIRC weighed 1.544lbs. Even with a Intelli, I would say it would still be under 2lbs.

Did I give you enough room on the fg slot to line up the front of the rail and the asa?

OPBN

The ASA lines up really well with the back of the rounded part of the front. The front not as much, but looks fine to me. I can get some pics up if you need.

That rail, RT length, with a slant in the back could be dangerous!!! You know, maybe done out of a e-mag rail.

Can’t be on an Emag rail because of the sear pin, although I could make them with the changes you mention.

This was for mocking up purposes. I have an inexpensive one on the way to see if it will work for my purposes, if not I will probably go with an AKA 2 liter+.

Waiting on BigE to fully test the new sear pin design, I don’t currently have air to do it myself. :)

I need a Shoebox, but with the market as it is with paintball it's hard to justify the purchase...

(Last I heard OPBN had his working)
