FAQ for Tokyo Marui Hi-Capa, 2011, 1911, MEU & Detonics type variants

That's interesting. Would you happen to know at what distance these tests are set up for (ie. 50ft from the target)?

I'm also not sure how all of this plays in to velocity vs groupings - I mean, I have no quantitative data to back anything up, but from what I understand, the tighter a bore gets, the more messed up groupings get (this is the claim made by Systema), and 6.03mm / 6.04mm has been found to be the perfect equilibrium between grouping increase and velocity increase. The theory, is that the tighter the bore gets, the more the BB is likely to bounce off the walls of the barrel, thus, imparting undesired trajectory effects.

I've never had the time or opportunity to collect good data on this, but it would be good to find out this information - collected in a tightly controlled environment. ie, bench shot, controlled (stabilized) power source, with consistent projectiles and done indoors.

Beats me, but I'd guess it to be much longer than 50 feet. I would assume 100 feet minimum. That's if any REAL usable data was to be acquired.

A question I just ran into, I got a new "SV" style hammer from ProG4(one with "SV" wire cut into the spur), I am using it on one of my Hi-Capa which originally uses the oval egg shape type hammer. The new hammer looks to have less "thickness" at the portion where it contacts the BBU that cocks the hammer. As a result the slide can't put the hammer into the cocked position and it just gets caught on the return stroke on the back side of the BBU. If I hand cock the hammer you can see that the slide is completely clear of the hammer with no contact. Now all my hammer are quite old and I haven't gotten a new one for a while and I am wondering if they have changed the tolerance or engagement of the sear to the hammer or something. I guess I can always go back to what I was using before, but I wonder if the new gun I build in the future will have the same issue....

So does that mean they're making defective hammers???

[RacingManiac]

I don't know, I won't go so far as saying its defected, but it is different from what I had before....

Might just be my gun, since most of the stuff on the gun I am using is more than 2 years old....

[RacingManiac]

I took a look at the new kit's hammer mechanism, it seems that the newer kit's sear is different also, maybe just the old kit that I have doesn't work with the newer hammer...

Hm. I wonder what the purpose of that is. I got some older hammer sets I've ordered from ProG4, I hope they still work because I don't intend on buying new sets anytime soon.

Does anybody know if companies other than Guarder are going to come out with new TM 1911 / MEU based kits? What happened to NOVA or PGC? Both of them have such low stock on all online retailer sites, let alone have new products.

[RacingManiac]

The only other things I've seen is the lower frame from Airsoft Surgeon, with the square trigger guard....

Whats annoying is that if AS is coming with 1911 lowers, why doesn't ProG4 make the Infinity LDC single stacker already....

Yeah that was my exact thought. I think after my 4.3 is done that'll be last hicapa I build.

What receiver are you using? I've seen this happen with a few non-ProG4/AS/IK receivers, but the engagement height of the hammer hook can be adjusted, in any case.

The SV hammers have always engaged a bit lower than other hammer styles, simply due to the shape of the top of the hammer, and not the hooks themselves.

I believe ProG4 has a new contractual lockout agreement which prevents re-selling AS contracted projects out the back door.

i have a problem lately that involved th SD nozzle inside an upgraded hi capa, the picture below show my old nozzle that suddently refuse to load BB's (still cycle normally, though rather weak) and fps is 360 (0,2 BB with bb manually put inside the chamber). when i cycle the gun with my hand slowly, i can see that the "pin" that suppose to push the BB forward is slipping above the BB. after i remove the nozzle, i noticed that it is kinda bend upward, and there's a hole on the side where some "rail" used to be.
the thing is, after i replace the nozzle with a new one (the one above), it still wont chamber BB correctly AND it breaks and have the exact same hole just after 1 magz of tries.

what have caused this? i use guarder power up gas which shoots kinda hard but i think its just straight up propane. i dont think it is caused by the pressure being to hard.
this also happens with my first nozzle AFTER i tried using long hi cap (50bb) magz. i dont know whether this is a coincidence or not, but my friend's hi capa with SD nozzle also cannot chamber BB from his long mag (50bb), but his nozzle is not broken and still able to chamber BB from normal magz just fine.

this is the picture i'm talking about


anyone have experienced similar case?
i already buy another nozzle (AS this time) but are afraid that something else in my gun is causing this and that my AS nozzle will be broken as well.
thanks

This happened with my Infinity build, which is a AS branded receiver from a few years ago.

I just noticed though they have 2 kinds of SV hammer listed on the site:
AR1324(one I ordered): http://www.prog4.com/db/product-show.asp?refno=AR1324

AR1608: http://www.prog4.com/db/product-show.asp?refno=AR1608

Note the latter is labeled for TM 1911, and uses a 1911 sear. I think they may have sent the latter in error. But This will be the first instance that there is a difference between the hammer...as I've used the 1911/Hi-Capa hammer interchangeably....

Well, if you have that hole formed on the side, then you'll lose pressure, and of course the slide will cycle weakly. If it doesn't cycle with enough power, then the slide won't be able to travel back far enough to chamber the next round. The piece that use to cover that hole is also responsible for guiding the nozzle, so without that part there, the nozzle would no longer be guided properly, which further explains why the nozzle is moving out of place and riding over the following round. All of the problems would stem from that missing piece and the resulting hole.

As for how that hole formed... beats me. Any number of things could have caused that. See how it contacts the blowback unit when you install it, and look for anything strange or out of place in the action that might cause that type of damage.

Because a new nozzle is also having this problem, I would also look at the blowback unit to see if there's any damage to it, and check fitment with your slide to see how it interacts. What brand slide and blowback unit are you using? What piston head are you using?

They are the exact same hammer. The only difference between the two kits, is the sear. Technically, that hammer is actually only for Hi-Capa anyways, as installing the half-cock nub will not allow it to function properly in a 1911. The location of the hole is different between the two systems.

[RacingManiac]

How do you adjust the engagement point? I'd imaging the sear/hammer needs to be reshaped?
