Gas gun shooting lube/liquid to barrel
Hey guys, just recently purchased a TM mk23 NBB and there's a slight problem.
Whenever I dry fire, the gas(with silicone lube) goes through the barrel and some of the liquid stays inside. Now that's not the main issue, the thing is, these liquid(lube) sticks onto the hop up rubber as well, which practically renders the hop up useless, as well as making my shots go everywhere. If anyone have a nominal solution for this problem, please do share(And please don't say "Don't Dry Fire", it's a lot harder than you think when you are on the field.) Thanks. |

How about don't put so much lube in?
Very little lube is required. You only need enough to keep your seals from drying out |

Yea... sounds like you're over-lubing like crazy.
You need 2 drops every 8 mags... And from what I understand is that you unscrew the propane adapter and drop it into the tank lid.. I'm not sure about TM, but I know with KSC over lubing = swollen hopup rubber. |

An NBB especially needs next to no lube since it doesn't have a gas piston in the non-existent blowback chamber, just a spring retained loading nozzle.
I haven't actually lubed my Mk23 OR its gas in 2 years, and haven't had a single problem. Another random note, install a firefly v-hop. That thing makes the Mk23 into even more of a laser than it already is (which is amazing ).

- Take a fresh tank of propane and attach your adapter. do not add silicon oil.
- Fill mag with propane and vent the gas by pressing the flow valve. - Repeat. - Replace propane adapter on original tank and stop adding so much lube. |

you're right and wrong. sure the gun won't necessarily need lube but the mags do to prevent the o-rings from drying up and causing a leak. He's just adding way too much lube.

Yeah, but it's simple enough to apply the oil directly to the mag seals if there's an issue, especially if you've already drilled out the half pin to fill up the mag's overpressure valve. I just don't bother with oiling my gas in the Mk23 anymore, she's a real tank.
On that note, my Mk23 recently fell out of a holster and the slide literally sheared off of the frame, as in the slide stop retaining pin being pulled straight up and off of the frame while still pressed through the slot in the barrel. I must guess that it was stepped on or something as I ran, because just hitting the ground probably wouldn't have done that. The chamber and barrel were pulled out and down at 45 degrees from the slide. After recovering all of two pieces that fell out and reassembling (the spring and spring guide on the nozzle), it's back up and running 100%, zero loss in functionality despite that massive failure. I just had to relate that, it was pretty dramatic, but the Mk23 impresses me to no end. It's just so well designed and well built (except for the overpressure relief valve on the mags, but it is aimed at the Japanese duster using market after all).

That being said, I would say just fire off about 10 mags or so without any lube. That should clear out the excess lube. Then don't over lube it. ACTH

uhh, guys, I haven't lubed anything. I got it used, probably last owner, or last last owner used too much lube .
Anyways got the problem solved, fired a few mags worth and the lube went away. Thanks |
