Bubba Longshot

Ok, I never realized that you could put a cutting wheel on a drill; I'll try doing that. As for the springs, I have a spare recon spring that I could add if the stock one is not enough.

What would you say is the hardest part in making a sleeper breech?

I plan on tackling this project in a few weeks, but have a few questions before hand:

1. As I don't have a 9/16 drill bit, would filing and sanding the inner barrel suffice? I imagine it'll take a long time, but I'll be using low grit sandpaper and have the patience. I'm basically just wondering if it's possible (would also wear down the sides with a 5/16 bit too).

2. As I also don't have a dremel, would using a mini hacksaw work for shaping the breeches? I could use sandpaper to smoothen out and finalize the edges. Like I said I have lots of patience for this, and I'm basically wondering if it's possible.

3. I plan on using the stock spring for the reasons I stated in previous posts ( low stress, ease of priming, 100fps), and am wondering how long my 17/32 brass barrel should be. From observing and analyzing other sleeper breeches, I'm guessing around 4-6 inches of brass; however, I have no experience form brass breeches so this is just an estimate.


Thank you very much

so i am going to endwar in june and i don't know how to sign up for it so can someone please help me

If you don't know how to sign up for an event, then you probably shouldn't go.

There is something called the Internet and you should just look it up. I believe there's a Facebook page where you get the info and sign up.

My Longshot currently is able to hit 100fps with an 8 kg spring. However, I would like to build a sleeper to make the entire system more consistent, and air efficient. I'd rather build a sleeper with a short brass barrel and use the stock spring rather than my current setup. That's because the lower spring load means less internal stress, and I can easily one hand prime without damaging the boltsled.

I plan on using full length darts.

Thanks

You do not need a sleeper breech to get 100 fps. That should be more than achievable by just a spring replacement (5-8kg, [k26], etc.) and AR/peg removal. 

Off the top of my head, your setup would hit somewhere in the 160+ fps area. 

A [k26] gets 100fps?! I thought it was more like 140...

 

 

Also, the only reason why I'm considering a sleeper breech is to maximize my Longshot's air efficiency while reducing it to the lowest spring possible. That way, I can get my desired 100 fps with low stress on my internals.

 

A 5kg sleeper with only 6 inches of brass can get 160fps?! That's very high. Maybe a 5kg with 4 inches of brass would be better...  Has anyone tried building a sleeper breech with the stock spring?
