Is it possible to order only that part at the end of the adjustment tool rod?



In the M14 video, he uses it to adjust the NPAS without disassembling the whole thing, which would be a time saver.

Anyone have any suggestions on how to get the nozzle to move freely inside the bolt carrier on a G39? Mine was pretty good, but I wanted it better, and somewhere along the line I managed to mess it up and now the nozzle doesn't slide in the carrier very nicely, the spring won't even pull it back all the way. Any ideas?

This is because the spring has been stretched out, you will prob need a new nozzle spring

Not in this case. I actually have two complete nozzle sets and I even tried the backup with a brand new spring, same result. It just doesn't seem to move smoothly in the bore now. I think it may have something to do with the grooves the nozzle rides in, but I have already filed them as much as I feel comfortable and it didn't do much..

If your outer barrel O-Ring is worn (typical if you disassemble couple of times) you can use the main nozzle O-Ring as a replacement (I'd assume you would break a nozzle anyways, why not salvage what's left of the broken nozzle).

A nozzle BB feeder break happened to me, I pulled the delta ring off (huang novesque D ring) and the O ring was in two pieces, I used the old O ring from the broken nozzle, (Thanks BTW) and I have a question.
I have everything put back together but my question is how tight is TOO Tight for the Delta Ring? I have the delta ring set to that there's a little play at the muzzle and RIS feels snug but with not a lot of force the RIS twists. Should I get some Blue Loctite or some Teflon tape in there first?

I really don't want to repeat the same mistake but I don't want to worry about the RIS rotating in game or loss of accuracy due to play in the barrel.

Oh yeah... Is normal for the new nozzle to be snug in the bolt even with some Silicone oil in there? The back seal O-ring seems a fraction or three larger than the old nozzle

Thanks!

That's actually a complete tool you can order from RA-Tech for $15. They call it a "Universal Joint Tool". http://en.ratech.com.tw/product/accessory/accessory.php

Ah thanks! Somehow I missed it.

Also, I've had an issue with my M14 last game. I think my bolt catch is starting to be worn down, but the bolt wouldn't lock back when I was out of rounds, but it would hold just fine if I just pulled back the charging handle, sorta like if the bolt catch didn't have the time to get in place when firing. Is it simply because the bolt catch needs to be changed or the spring in it is too weak?

Thanks!

How full were the mags?
I'm guessing propane?
I'm not too familiar with the M14 but if the gas pressure is getting low it might still have enough to cycle but It doesn't go all the way back to catch the bolt catch.
I know that can be a problem with pistols in colder weather with propane.

Feel free to flame.

Nah they were full and shooting in the 330 fps-zone.

Got an We scar couple days ago installed the npas kit. Fully open shooting at 540-560 almost closed 440-470 with .2s . T_T I need to get it at 360 with .2 at least. Ant suggestions?

Lighter floating valve spring (like that of a pistol). Or try to buy the standard nozzle, I think what you guys get in Canada is modified to come shooting as hot as your laws require.

Im anxious about the new nozzle. But I have to wait to hear from you if there's any modifications.
