This is just a demonstration remember the release date is still not set other than "early next year" and I would assume that Escort would work out the kinks as they are very good at doing that, and they might develop a reciprocating bolt by that time too.

not much point making the actual moving bolt part of the mechanism bolt shaped when it comes to an M16 - seeing as the reciprocating bit is half way along the receiver rather than up at the ejection port where the hop up and barrel are sitting :)

 

Easiest way to have a moving bolt on these is a lug at side of the moving blowback chamber that a fake bolt can be attached to That fake bolt then extends beyond front of the gearbox to hide the hop unit etc

 

however having viewed it a few times this particular system doesnt seem to have much bolt travel at all - the spring is behind the mechanism ala an AEG spring behind an AEG piston and the whole lot is inside a gearbox shell I'd reckon on a powered blow back travel of say three or four centimetres or so tops?

 

now what you could do is have an elongated slot in side of the bolt so that it can be drawn back a fair amount of distance by hand before front of the slot engages with the actual bolt - that gives you ability to mimic plenty of travel when someones cycling it by hand, while the rear end of the slot sits snugly against the lug on side of the moving bolt when at rest - that way as the moving bolt moves rearwards it pulls the fake bolt with it. Trouble is during the pull stage (ie while firing) the bolt travel will be a lot shorter than when cycled by hand.

 

Thats only way as yet Ive been able to design a decent amount of bolt travel into an escortised AK though its not using an AEG mechbox shell

 

however really comes down to where escort are positioning these - as a be all and end all solution or as a taster to encourage folks to invest in a rig get used to external hoseand then be tempted to move up onto full blown escort guns? If it gives a decent kick, feeding doesnt go down the pan, semi is sorted for various fire select requirements and it has a reasonable price Id shell out for a few even if bolt travel is limited.

I don't know if anyone here frequents the ClassicAirsoft.net board, but Paul (Sniperx) announced this new Escort system mechbox on the CA board and also stated the retail price of this mechbox conversion kit should be under $200 USD!

 

For that price I think I'll be converting my AK for sure... time to start shopping for a palmer's rig and co2 tanks! :lol:

if you're in the UK never buy a rig untill you're sure which propellant is available locally

 

a CO2 less common than in the past

b HPA fine f you have a dive shop nearby to fill a scuba tank at

c absolutely hee haw if you're in an area thats got no CO2 suppliers left and no dive shops to provide an HPA alternative

 

while you'll need to source the palmers stateside buy the other components in Uk - particularly the tank which has to be UK EU aproved and not a US approved tank

Sorry freq88, it looks like at least the first run of these gearbox conversion kits won't be compatible with the Vz61/MP7/Mac-10 style AEP gearboxes. However Paul (Escort's rep.) did mention that AEP conversion kits might be a possibility later down the line.

 

But in the meantime, can anyone say "gas blowback P90"? :D

I'm not sure what the plan is but I hope they sell the mechbox (say a v3 one) then you also buy some parts for the specific gun, so if you wanted to put one in a g36 you would buy the mechbox + the parts to get the ejection port to blow back, with the ak you could get a new bolt etc.

OKK...boy did this blow up overnight....1600 vid views in 8 hours, 2 pages on CA and 5 pages on Arnies....

 

NO way I can keep up with individual questions. So we'll answer what we can.

 

FPS is unknown right now. Until we get the tappet plate hooked up we can't really get an accurate read. Preliminary tests are showing, JP pressure=JP power. That video was shot at roughly 100psi. The design is built around the standard AEG cylinder, not the AEP...maybe later. This is really only a demonstration of capability, we are looking at producing a stamped steel mechbox similar to the ICS models. IE, the upper remains the same...but the lower changes based on selector systems and trigger positions. The pricing is correct and accurate. This is not an Escort replacement. Nothing can compete with pounds of brass and aluminum moving. This is a way to get new users interested in gas gun and a way to get new gas guns on the field...IE G3, P90, etc. This is only phase one of the grand scheme of the HGS. The inner valve on the airshhaft apparently has been changed somewhat, unfortunately, when I got into work, it was already sealed up. I plan to run a durability test similar to what we did with the MG42. Hook it up to a compressor for 24 hours. Maybe I'll do a youtube video with a clock next to it. And strangely enough, most of the shock is at the rear of the unit. Also, with the decreased weight the crush oring, if it has one, will not be damaged like before.

 

Thats it for now, maybe more later.

 

That clears a few things up for me. Looks like they are still a few months off. Stuff like this keeps me sane though...

Well i live in the middle of nowhere so no co2 im guessing :P may have a dive shop nearby though (well probably not), live in hope :)

 

If by the 'middle of nowhere' you mean the country then their is probably a gunshop near you. They will sell airguns, so they'll be able to tell you where you can get a HPA Bottle recharged. They may even have a dry air compressor themselves.

From what he said on CA.net its just the gearbox internals, you supply the gearbox shell, so we get to see if blowback makes the failure rate of V2's even more epic than it is now.

I also agree, version twos are weak against springs with a plastic piston.

 

This is alot of brass moving back and forth, and its slamming the front end of that gearbox with alot of force.

 

I see alot of crying eyes

actually from what was said on CA net last I looked the suggestion was for a two part pressed metal frame - with the cast alloy mechbox more of a proof of concept than anything else

 

ie standardised upper shell and various lower shells dependent upon particular application

 

actually is contained in the quote already carried above:
