Marui 1911 Upgrades

HelloKitty · September 30th, 2007, 07:30

Sorry I don't know what a rocket valve is or where it's even located.

In stock form, the Marui 1911 worked perfectly. But with the nine ball bucking I noticed it doesn't hop .2's very well, it drops off sooner than with the Marui buckings.

Is there any guide as to take out the nozzle? I want to try putting the Marui one back in to see if it changes anything. How do I begin doing this?

The rocket valve is inside the nozzle. That nozzle assembly should unscrew from the rear of the slide and then you can remove the nozzle. Do this carefully as there's a narrow spring (or 2, since I've not worked on a 1911) that you don't want to lose. Midway down the length of the nozzle is a super-tiny screw. I had to look hard for the one on my Glock's nozzle and I missed it a couple of times. That screw holds the valve blocker in place.

It shouldn't be the nozzle, though. The Guarder nozzle isn't long enough to push so far into the bucking that the BB skips the hopup. If it did that, the BBs would just roll out.

To make the arm push down harder, just put something, almost anything, between the hopup arm and bucking. Make sure it'll fit neatly between the two.

Check the angle on this part. It won't be the super soft hopup, that would if anything put too much hop on the BB with low settings. HelloKitty I'm using a FireFly soft hopup with my TM 1911, a Nineball 6.03 barrel and a guarder nozzle.

HelloKitty · September 30th, 2007, 19:21

Wow I'm so stressed right now... I was putting it back together and now the inner barrel + hopup won't push all the way into the outer barrel anymore.

It's very close to popping in, but something's not letting it go any further.

I tried dremel sanding the inside to loosen the tolerance and any sharp edges but it still won't budge, any ideas?

Scooby Steve · September 30th, 2007, 20:45

I had the same situation when I put a metal outer barrel in my 5.1. Insert the inner barrel but it won't go straight in all the way because of what sticks out on the side of the hop-up unit. Try tilting it a bit to the right as it goes by that first ledge. The hop-up won't go in the way it's resting on that second ledge. Also keep an eye on that notch as the bottom of the hop-up has to fit in there, too. Both parts are metal so there's no flex. Just keep trying and you'll eventually get it. Watch those fingers because I took a small chunk of meat out of my thumb when I was working on mine.

Crap I took out a spare KJW 1911 outer barrel and I could get the hopup+inner barrel into that one.

I put the rest of the gun back together and fired two shots, the third shot locked the slide 1/3rd of the way back. It's stuck so hard it won't budge at all. I can see the nozzle plugged into the hopup from the slide being pulled back just enough to spot it through the ejector cutout.

Any ideas?

Scooby Steve · September 30th, 2007, 21:58

That's normal for the nozzle. If the slide was pulled back more it would take the nozzle carriage with it. I was just firing my 5.1 after putting the Shooter's Design outer barrel back in and the stock slide locks back after each shot. If your hammer's back take out the mag and dry-fire it. That might let you move the slide.

HelloKitty · September 30th, 2007, 22:36

Nope, still stuck. I was able to move the guarder nozzle back into resting position, but the slide hasn't budged once.

The hammer is stuck in the back position, with or without mag the slide won't budge.

*sigh.

Try folding a towel on the edge of a table and tap the back of the slide using a straight, downward motion.

HelloKitty · September 30th, 2007, 23:46

K, I'll go do that now.

HelloKitty · October 1st, 2007, 00:35

Awesome man, I got it back in and swapped that shitty KJW outer out and finally got the internals back into the nineball silver outer barrel.

Okay so now that it's back together, two small issues came up.

1) every 1 or 2 shots out of the entire mag will get very little fps, enough to blowback and fire but you can tell by the sound of it that it feels limp like a little "puff" sound instead of the normal "boom boom"

Not sure how this came about now could it be too much lube?

2) The mag catch screw keeps backing out fairly frequently, and I have to turn it back with a flathead screwdriver every few mags. Any remedies?

It was too dark to see if the hopup is any better after all this adventurous surgery, but I'll check it again tomorrow. But thanks to your help it's back together and the main firing action is working albeit the minor problems outlined above.

Sounds like an air seal problem. You're going to have to look at the valve that's inside the nozzle. I'd also check the piston head. Maybe it needs to be tightened down. Are you filling the mag properly? Any leaks in the mag? Duster or propane? Stock TM 1911s are hard on gas and you have added a lot of metal to your piece. Maybe a high-output valve is needed. When you shoot are you plating the mag with your other hand? That could be pushing the mag up higher in the grip.

Loc-Tite.

HelloKitty · October 1st, 2007, 13:52

Same problem occured, hopup not being responsive. Acts like no hopup is on at all when I have it almost maxed.

I took it apart to try to bend it to be as 90 degrees as possible and now I'm running into the old problem of not being able to get that damned outer barrel fitted with the inner + hopup.

1) Actually today it seems okay today, maybe I was just pushing up on the mag just enough to make it do something funny last night.

2) How do I take it out completely? I can only turn it slightly.
