Superlight Mag Trigger?

[nerobro]

See that's a problem. The L7 bolt has a buttlaod and a half of force on it... so to speak. So you can't use such a hairy catch on the bolt. Well you can,... but you'll get doubble fires, full auto fire, and that sort of theing. not controled fire like you'll get with a LX bolt. The on/off needs to have enough force to keep that sear in place..

nope, i accualy added a part. i wont say what becasue my best friend is making an mpeg that ill post later in the week

and skoad, yea the distance is short but the pull is light too as i stated above

mpeg up yet? cmon let us in on your idea.

[Paintchucker]

Hmmmm...

When was that YGrip coming out????? LOL

[AcemanPB]

I can't wait....

Couldn't something be done to the diameter of the on/off pin? Would that change anything?


Now it's Level 10 all over agian..... soon we will have videos of Tom firing a mag 20bps with his tougne :)

[nerobro]

yes, we can. But from a production standpoint there are only certian o-rings we can get our hands on in any kind of quanitify for a reasonable price. From what I understand the lower half of the rt on/off pin is the next step down in o-ring size from the on/off top... and there isn't much inbetween.

By carefully ajdjusting the angle of the bolt-sear interface and by adjusting how much force the LX has at rest you coudl tune the trigger feel signifigantly. Hm... probablly the best tuning tool for this would a a whole boxload of LX springs of close rates to each other so you could adjust the trigger nice and light.

My frist guess is that this will use a "normal" mag on/off to reduce the RT effect, and provide a fairly constant spring action against the sear so the gun wouldn't be dangerously unstable (wher esomething like a sneeze will cause the gun to spontaniously fire) under normal conditions.....

Yea...I second that....lets hear it BT

what if instead of a reverse sloped sear face, we used a roller sear like cockers use. It should accomplish the same thing, but with a much smoother pull and less metal on metal grinding.

[nerobro]

roller sears on cockers usually don't have the roller at the "sear surface" though a guy on PBN has done that with a spyder sear. It would not provide the "finish the pull" for you trick that the sloped sear face will provide. and finding a berring that would work... Hmm... Definitely worth a thought though. it would work well with the current bolt design and even provide lockup at high pressures and woudl probally work with a L7.....

I like it.

Wait a minute -- are you sure you have to alter the bolt to get this to work? Changing the sear angle will adjust the way the geometry of the contact works. But once you reduce the sear to a 90 angle at contact(or less) I'm thinking that the bolt geometry might not be that important.

Modifying the bolt geometry would leave you with a contact "surface" with the sear; leaving it the same would leave you with a contact "point". What I'm thinking though, is that the difference between "surface" and "point" once the sear angle is reduced becomes minimal.

The disposition of forces acting on the juncture should be almost itenticall. All that a contact surface will do is give you a little more friction, and distribute the stress on the bolt/sear over a little wider area. But I'm guessing that whatever frictional differences will be minimal, and that the sear and bolt are strong enough for the stress factor to not be a problem.

Does this make any sense -- or do I need to draw a picture?

Has anybody tried modifying just the sear while using a lvl 10?


EDIT: Oh, and as an adendum, a roller sear a bolt with the current angled face might actually work out very nicely.

[nerobro]

The reason I was emphsizing a surface was for durablity concerns. if we were working with a point, the edge of the bolt would wear very quickly. if done right, with flat mating surfaces, or at least matching ones, like we have on the current mag we could get some rediculous life out of such a sear and bolt.

[Cristobal]

Are you sure we'd have to use a "flat matching surface" for durability reasons? I'm not convinced that a "point" configuation would see any more stress than the lip of the bolt already sees normally.

ha ha

you guys are gonna have to wait. because its a dam light ad short pull but its on a benchy so i gotta install trigger stops or there is slack in the trigger

[AGD]

I am posting an update on the mechanical trigger so you guys can stop talking about mods that will get someones eye shot out. The problem with the sear angle mod is that the gun will fire when it degasses.

This is serious stuff, you mod a sear and someone looses an eye we get sued. If you modified it we have to sue YOU to get the blame and the cost off us.

If you think we are kidding ask Tippman why we had to sue them in a lawsuit we had because without his tank our gun would not fire. This is standard legal proceedure and I would expect him to do the same to me (we are still friends). You modify something you are now the MANUFACTURER so unless you have a boat load of insurance you could loose your house, car or get your wages docked for life.

[BTAutoMag]

dont worry mine's safe. i had 3 misfires when i jolted it to hard so i had to make the trigger heavier:)

[Brett23]

What was that about a lawsuit against Tippman about a tank??? Me confused by what Tom said.
