l85 guy Posted August 14, 2009 Report Share Posted August 14, 2009 do you have to rack back a bolt or something to fire it, like on a GBB pistol or the Madbull 470? How will the fire selection work, i assue it will work off the selector already on the guns, but will it still be like a selector plate? Link to post Share on other sites

MagnumBB Posted September 7, 2009 Author Report Share Posted September 7, 2009 Been away from Airsoft for the last few, trying to maintain my love for the hobby, seems I am haven't lost my love for the mechanics of it though. -Updates- - NBB Kit - Unit will fit into a standard gearbox. Holes may have to be drilled for the trigger, but the actual unit will fit based on gearbox provisions. - Trigger pull is only limited to the trigger return spring ( sub 3lb break) - trigger travel is 1.4 inches - I want to build this kit with the least number of parts available. So far only 2 parts move, trigger and nozzle assembly. - First GB will be V2 since SPR's of the armalite platform are dominate. next will be v7's - Sub $250 price tag if all goes well. - Since there is no impact points, will either be made from alum. or brass. Steel will be overkill in every sense of the word, not to mention costlier tooling. - Unit might not be one size fits all, since different companies have different tolerances on hop ups and general dims. - Semi-Auto Only with no provisions for Auto. This is for fields that require high powered rifles to be fixed to semi-auto operations. If you want this in Full-auto, too bad, stay Electric. - GBB Plans - I am working on my own SMG designs. First proof of concept will be a ppsh-41 in .45,( I have a spare stock) being dubbed the Mp41(r-45). Being in the great state of Kalifornia, ppsh drums and magazines are hard to come by ( also being caught means 10 years in the pen) , so TM Thompson mags and drums will be used instead. Auto only. What will this lead to? Lets say some CQB Fanboys will be very happy BB's - Different formula, pretty much a complete divergence of my previous path. Might be take getting used to, but with these conventions, there will be 0% Air bubbles... Absolutely no possible way for it to happen. impeccable tolerances and IN WHITE! Reviewers will be contact in 2-3 months once tooling is complete. These will be in .36g with a possible .38g down the line. Ordnance - Working on Pocket Nerf Vortex replacement with howling whistles. Closer to 40mm dimensions to allow propper expansion vs stuffing the Nerf in. Shape is TBA Link to post Share on other sites
pedrosalas7 Posted September 7, 2009 Report Share Posted September 7, 2009 hey magnum all sounds good, but any ETA on the NBB kit? Link to post Share on other sites
MagnumBB Posted September 7, 2009 Author Report Share Posted September 7, 2009 hey magnum all sounds good, but any ETA on the NBB kit? I'll have a printed prototype ready in a month. Progress is slow when I only have 2-4 hours a week to devote to projects. Link to post Share on other sites
pedrosalas7 Posted September 8, 2009 Report Share Posted September 8, 2009 oh i see... so my guess would be end of the year AT least... one question though... 1.4inches of trigger travel sound like a lot, is it just me? why is that? Link to post Share on other sites
MagnumBB Posted September 8, 2009 Author Report Share Posted September 8, 2009 its currently sitting at 1.4 inches for 2 reasons. I want to allow maximum chamber pressurization time between shots. I can see that my system might be put up against rapid fire testing and the arm swing is to allow full expansion before firing. second, is green gas/propane users. I don't want to force people to use co2 if they don't want to. Because it expands and recharges at a different pace than co2, the extra room is designed for that. If this were a solely co2 system, and users fire at a pace of 1 shot per second, then I can shrink the trigger pull to under .75 inches. but you have to keep in mind the trigger pull is extremely light. most likely on par with an aeg with a bit of dirt in the action.

pedrosalas7 Posted September 8, 2009 Report Share Posted September 8, 2009 if i were to use CO2 or ever HPA would it be posible for me to mod the trigger to have shorter travel? Link to post Share on other sites
Horsem4n Posted September 8, 2009 Report Share Posted September 8, 2009 im looking forward the the V7 kit. im a patient boy. now to decide on which M14 to stuff it in. if you decide to eventually slink to a kit for the AtoZ dragnov, tell me. i have an A&K sitting here and im tired of spring rifles. im going for an external gas feed. you can put me on the list for a definite buyer for the M14 kit. SVD too if you decide to tackle that project, i will even lend you mine if your team mate denies you the use of his. Link to post Share on other sites
black shot Posted September 8, 2009 Report Share Posted September 8, 2009 definitely going to build an M1 garand when the v7 gearbox comes out Link to post Share on other sites
MagnumBB Posted September 9, 2009 Author Report Share Posted September 9, 2009 if i were to use CO2 or ever HPA would it be posible for me to mod the trigger to have shorter travel? Yes. The figure of 1.4 is only what I have on this build. In the end, I ant a max of 1 inch swing. hopefully it will sit in the range of .6-.7 inches if you decide to eventually slink to a kit for the AtoZ dragnov, tell me. i have an A&K sitting here and im tired of spring rifles. im going for an external gas feed. you can put me on the list for a definite buyer for the M14 kit. SVD too if you decide to tackle that project, i will even lend you mine if your team mate denies you the use of his. The SVD is a possible candidate, but because this is a nbb build based on a gearbox, it might slighly difficult. Then again.... a GBB kit for the svd would just be so much more fun... granted you won't have a wide range of power control or consistency. Link to post Share on other sites
Username_Here Posted September 9, 2009 Report Share Posted September 9, 2009 A GBB SVD with at least 60-70 meters of effective range would make me very happy. Gladly lay down cash for one. Link to post Share on other sites
MagnumBB Posted September 9, 2009 Author Report Share Posted September 9, 2009 A GBB SVD with at least 60-70 meters of effective range would make me very happy. Gladly lay down cash for one. My only concern with that is if the body will stand up to the abuse. I can try something on par with the kick of an escort mp5, but if that body rattles itself apart, it would feel terrible. If anything, the bolt would travel, but it would feel like firing a .25acp, or maybe a .38spl a total redesign with a drop in reinforcement cage would mean $$$, but 7.62x54r appropriate kick Link to post Share on other sites
l85 guy Posted September 12, 2009 Report Share Posted September 12, 2009 The semi box would go nice in my SR-47, shame I couldn't have both though. beggars can't be choosers. I see a bunch of gas gun stuff being purchased in the near future. Link to post Share on other sites
Horsem4n Posted September 13, 2009 Report Share Posted September 13, 2009 im fine with NBB for the SVD. but youll have a couple problems with the build quality on either the AtoZ or A&K versions. both have sud par seals between the nozzle and chamber and both have barrel wobble issues (though, i have a temporary solution). if you could figure out the nozzle issue (maybe by making it plastic) it could be a fix all solution. but i guess that discussion is for another time. are you sure you want to make a version for armalites first? it seems to me that you have more buyers for the M14 version. maybe you should make a poll topic, asking for people who WANT to buy one decide which version they want more.

SVD The reason I want to do a GBB svd is because all the necessary components are there for me to make it work. the hop up in the gun is very compatible with the gbb escort designs. Granted that a sub structure will have to be designed for the unit for the front chamber to work. Having the unit NBB would be on par in terms of setup because of the needed support structure. As for the NBB box. As far as I am concerned, 80% of the unit if universal. the only things needed to make something v2/3/7 is a different trigger linkage system. with the V2/3 gearboxes,internal operating triggers are available. vs the m14's design of a trigger external to the gearbox means I will either a) try to use the current trigger to make it work slightly shift the trigger design c) say screw it!, drill 2 pivot holes for a new trigger. I am leaning towards option b, because I would like users to be able to switch back and forth and replacement v7 gearboxes are something of a rarity vs v2/3 units. when i have a satisfactory unit ready, I will poll the users here as well as AS-R and see which people prefer. The other thing I am concerned about, is how many people want to use this with propane in the stock vs running external co2. the gas tank in this would be on par with 1/2 a 9.6v large battery in the stock.
