the AZR products dont interest me since they use on board gas canisters.

 

If im going to be using co2 id much rather be using an external rig. Yeah i know, i cant believe i just said that. For the m4, the AZR system looks VERY similar to the rap4 design where the canister replaces the buffertube.

 

Knowing me, id crack the canister right off of the gun so yeah, i think im going to stay away from that design.

 

The only thing that interests me is that it appears as though they may be producing a gas powered PGC styled m249 box. If so, if it is externally powered ill be all over that thing like white on rice. If its blowback i would consider sacrificing one of my cats for it.

So yeah, this is going to be;

 

Under $200, unmodified structure of the gearbox, available for ALL versions, and compatible with TM hop systems, according to sniperx.

 

Hey thanks!! Gotta get me a cheap AK and buy this! Might, probably will, come out cheaper than the $435 WA M4! :D

potential downsides shorter blowback stroke than previous designs, use of an aeg mechbox reducing your options as far as a moving bolt goes and need to squeeze it into an AEG mechbox shell at all (eg why not just go with a skeletonised steel frame with front and rear support of the action and box section underneath for the trigger group)

 

in general terms though I do beleive its the right way for gas internals to go - avoids redesigning the wheel each time they want to adapt to a different rifle layout no need to carry any sort of inventory as far as externals go and gives folks a dual purpose weapon they can swap between gas and electric. In the UK with restrictions on RIFs now in place could give a whole lot of pre October guns a new lease of life

 

dboys steel AK and a gas mechbox conversion = 280 dollar win

I'm skeptic about these GBB "wonder gearboxes" (not just Escort, in general) since the MGC (Monster hybrid) and Madbull products failed:

 

Light recoil route --- pretty much pointless (even a stock Marui MP5K has nice light recoil), unless the product is MUCH more consistent, reliable and serviceable than AEG gearboxes. CO2 capsules are pain in the nether regions, internal gas supply won't cut it for an automatic rifle.

 

Heavy (Escort level) recoil route --- pot metal gearboxes will break sooner than later, heavy duty, reinforced gearboxes will cost $$$, may have fitting problems. AEG hopups may not react well to heavy recoil and vibration (feeding and consistency problems). Requires external rig and the regular AEG user will whine about that to no end.

 

Externally powered, adjustable, "no recoil" gas conversions would be easier to implement on current AEG designs.

I dont see them being unfeasable using a steel skeletonised mechbox - ie take the MP5 trigger group box design of the escort MP5 extend it at the rear to incorporate the MP5 airswitch and recoil rod retainer and extend it at the front to provide a mount for front of the piston chamber, and you then have a pretty strong frame for the parts to be mounted in.

 

Overall stroke in that sort of setup would be my main concern - by time you incorporate space for rearward travel of the airshaft for disengagement, and space for a valve behind the recoiling cylinder (plus a front face for the cylinder of X thickness) you dont have a lot of space for travel. Particularly in a V2 design if you're tight for space for a recoil spring and arent going with buffer tube storage of the spring

Yeah but HFC134a makes us cry. The performance is deplorable. Here's hoping WA optimized the system and its actually good for you japanese fellas.

 

Btw, to the original poster, how did you stumble across this? I didnt see anything on classicairsoft.net which is a real surprise.

 

 

The news was releast on airsoft-news.eu

It looks good. Gearbox strength issues aside this'll be a great product for people wanting to dabble in the black art of 'classic' airsoft without spending a fortune on a skirmishable gun. It won't be a rewarding to shoot as a proper SP M16 or Escort MP5 but it'll be a good middle of the road solution.

 

I however take the intended price tag $200 with a large pinch of salt. $200 is what Escort are wanting to charge for a Sun Project m16 bolt catch <_<

I actually find the fireselect mechanism for these as more intriguing than the blowback part considering the number of variations required there

 

Ooh Good point, i wasnt even thinking about that.

 

I just wonder now how these are going to stack up against full blown classic guns like a Classic Army MP5 w/this mech vs the Escort MP5

 

Hehe, im still glad i saved those metal g3 lowers from when i converted all mine to the G&G one peices, whew

I was thinking about this a little more and perhaps i jumped the gun with my unchecked enthusiasm last night.

 

Part of the fun of the escort guns is not only the felt recoil but the fact that you actually have a faux reciprocating bolt. These gearboxes dont seem to feature that.

 

Why would escort not have designed the actual blowback unit to look like a fake bolt? On say an m16, the place where the cylinder window resides is in the ejection port area of the upper receiver. By making at least the right side of the blowback unit the same shape as an m16 bolt we could have at least a visually moving, realistic appearing bolt. Of course, doing that kind of work means the gearbox would only really have a reciprocating bolt on the m16 series.

 

Also, as per sniperx's comment, whether its true or not, he is leading us to believe we can drop this gearbox into any version two or three platform. Like snorkelman pondered earlier, im really curious as to how the selector mechanism is going to work.

 

At 200 dollars a piece that certainly is a good pricepoint but i can only imagine how many damned mechbox shells im going to end up going through. While it is heartening news indeed that this is a version 3 mechbox design, i have zero faith in pot metal for something like the escort system.

I'll admit my initial enthusiasm has dampened as well. While it appears to be very easy to hook a blowback AK bolt up to this, it would require partial disassembly and machining of the existing gearbox. I'm also less than convinced about the pot metal's durability as well. I am looking forward to all of the other options out there, I hope that we as consumers can pick and choose which to buy.
