Trigger pull/reset modification experiences.

[CitizenPete]

There are a few threads regarding trigger rest from the past, however after searching them I have more questions than answers.

Due to the striker sore-point I am almost afraid to head down this road on trigger modification, but the long pull and reset on my OOW VZ2000 leaves me wanting.  The various VZ builds I am keeping in my collection (OOW, Czechpoint/CSA, VZ2008) are/will be tabbed.  Working with a local fellow who does top notch welding, two VZ2008 carriers are there to be tabbed this week.

  The VZ2008 and the Czechpoint are perhaps different, but I have not run them hard or long enough to start complaining.  One of the best resets I have on a combloc firearm is a good implementation of a Tapco G2 on an Allied Armament Polish AKMS -- very crisp and crisp hair trigger, with short reset.  I know that comparing an AKM FGC hooked trigger and hammer to the VZ FGC striker function is like apples and bananas, but its the reset distance and feel I am after. If that similar reset distance and break could be accomplished on my VZ2000 (or CSA VZ Carbine) it would be great.

Bonesteel Arms offers a $65 US made trigger group available for VZ2000/VZ2008 rifles, however the online reviews are mixed and the part is listed as back ordered which concerns me after hearing about other wait times for Bonesteel parts.  Is it worth the "n..." month wait?

If anybody has experience with the Bonesteel trigger group, and how it improved the trigger pull and reset, could you post your most current results and opinion  here?

Does anyone have experience with the VZ58RIFLE.com FCG offering and the results?

Does anyone have experience with a custom trigger job or polish and how that worked and what was done?

CNC Warrior has the individual trigger parts in stock.  http://www.cncwarrior.com/category-s/1897.htm

A little more expensive than bonesteel, but not terribly so...

IMO, the wide sear makes a lot of sense, especially once you realize how the original sear setup was intended to function...

Don't know about about VZ58rifle trigger. They have their own disconnector, but that's all I've seen there...

[RSR]

I've been thinking about this and creep is overall a function of the length of the disconnector length -- where that protrusion is.  I think Bonesteel's disconnector is slightly shorter -- where that protrusion is (intend to purchase after the holidays to compare) is likely shorter than either military or Century's...

Trigger reset, we're talking about two things. 
1) The gremlin issue that's solved with the tab -- disengaging the sear from the disconnector
2) The rotational interplay between the disconnector and the sear.  The disconnector pulls the sear down releasing the striker.  Trigger must be released far enough forward for the disconnector to re-engage the sear sear.  This can only be adjusted through modifications of both the sear and disconnector, where/how they interface.  Due to the function of this interplay, trigger reset will always be slightly longer than some of the premium hammer triggers we're used to on ARs and pistols...

And as far as trigger weight, there's the obvious polishing.  Primarily and striker edges/interface should be most significant..  I'd think some flitz on those surfaces would be sufficient.  A new striker to start wouldn't hurt either as precision on well used parts is difficult to say the least...  Forward facing edge of striker latch on bottom and rear facing edge of sear. 

The lever trigger springs are relatively difficult to adjust weight on.  The best method would be to remove in entirety and fab  a standard spring of specific weight, but it'd be a substantial project I suppose.  But bending that spring up and down will allow some customization of weight.  Much lesser significance, but still a part is the disconnector spring which pushes up on the disconnector to engage the sear and is compressed as the the trigger is moved to the rear...

Anything south of 4lbs, just like with Glocks, I think would be causing both safety and reliability concerns considering how striker fired weapons work. 

Hope this helps.  Might post a short video at some point to illustrate.

And this review on Bonesteel's site is describing the standard gremlin to a T.  Not sure how OOW trigger mechanism is from the start but w/ no tab, I can definitely see how modifying would suddenly exhibit a Gremlin.

Light strike malfunctions now. Reproducible.
Also little to no apparent change in take up or creep.
VZ 2000.
Getting a second opinion to check the gunsmith's work. I'll write another review and take it all back if it wasn't the components and it was the work, but it "appears" it was modified (narrowed) and installed correctly.

Thanks for your thoughts and input.  I was hoping that you would reply along with a few others who I would expect tried to improve their trigger function.

I will have to read your response several times and get my head around it - esp. the spring bit.  Beside the break, it's the long trigger release required for reset thats killing me. The tab has no effect on that.

I was thinking that a mod to the disconnector affecting the front and angle at the top when released could help, but I would acquire an extra working one before the file comes out.

Regarding the user comment on Bonesteel, I hadn't caught that statement was related to the Gremlin, but you could be correct - that it does sound like it might possibly be that fellows issue.

I might talk to OOW directly regarding a mod although it might be a costly venture for them to work on one of my rifles. The mod/repair queue could be long as well since they came out with their HCAR rifle.

Thanks for sharing your ideas on this.  Much appreciated.

Spent some more time obsessing over the full auto trigger and my skeletonized training rifle. Posted those comments in the gremlin sticky.

Might be helpful as you think about this.
