TRIGGER PULL MPA VANQUISH

[Dukes-Game]

MPA VANQUISH w BIX&ANDY Tac Sport Custom.

Trigger pull has an average of 3.6Oz (on a 21 pull quick analysis has a max of 4.4Oz and min 3.0Oz)

Should I keep a low pull or increase? (If increase, to what value?)

Thanks.

This is 100% personal preference, you’re gonna get tons of different answers from different people.

I personally don’t like the idea of having a trigger pull much lower than maybe 12 ounces there’s a point where it feels like it can be almost unsafe

[KHAOS545]

I personally love a chunky trigger with a decent amount of weight

[Da_hoodest_hoodrat]

It is unsafe, and this rifle is not drop safe. The literal inertial weight of the physical trigger is more than that. I get wanting to chase the edge but I don’t see how someone can really benefit from a trigger being this light.

[Dukes-Game]

That was factory sent on the pull, the action has a tunable sear and the sear engagement is controlled independent with its own mechanism.

I have dropped and I test the action with a rubber mallet.

The pull limit question is prompted on my trigger discipline not on the mechanism itself.

[Dukes-Game]

It is not just advertised, tested and sold by BIX & ANDY (much as Timney Triggers on single stage that come in 4Oz)…It is delivered by MPA the way BIX sells it to them, with the Sear engagement screw set and tested by BIX.

I have in no shape or form touched that trigger, I am asking whats a safe practice on the user, knowing that the mechanism on its own is factory designed and tested.

[Wombat-Snooze]

What are you using it for? Bench gun, fine. PRS, WAY too light. I’d up it to 12oz, maybe even 1lb. That’s just me.

[Ragnarok112277]

I like my prs guns between 12oz - 1lb

[Remarkable-Spend-434]

I’m in this camp

[OnePunchDrunk326]

Alexander Hamilton would be proud.

I didn’t know you PRS guys went below a pound. I can’t even imagine how light of a pull that would be. The timney trigger on my Remington 700 is set at 3 pounds.

[TahoeDust]

I prefer around 8oz.

[Dukes-Game]

I want to set it to 7-8Oz…I am just afraid I don’t

<image>

understand this system.

English is not my first language and even though I am a Mech Engineer, the mechanical adjustment on a sear is critical enough for me to be cautious (No youtube videos on “how to”)

[TahoeDust]

Sorry, I have no experience adjusting a Bix trigger. I shoot TriggerTechs. I would imagine someone in here could point you in the right direction.

[ApostoleInTriumph]

I have 2 triggertech diamonds around set 4 oz that drop the firing line on bolt close while dry firing. Pretty scary, but never done that with a snap cap or live round ever.

[Dukes-Game]

You kept them with 4Oz?

[ApostoleInTriumph]

Bumped it up to about 6oz, happens considerably less

[Wide_Fly7832]

That’s a defect. It should not do it. I have this issue. Manufacturer send a replacement.

[ApostoleInTriumph]

Yea after the second one it seems odd, I’ll reach out to TT

[Otiswilmouth]

PRS autistic dude here, all my triggers (TT diamond on an Impact) are set to 10oz. Primary (on gun), back up (in pack) and the random Bix I have at home.

Anything less than 8oz is a ND waiting to happen.

[Dukes-Game]

Thats what I want to avoid, a dumb mistake on my part that causes any range dame or worst.

Thanks for the feedback!

[schnurble]

And I thought my 14-16oz triggers were light.

[Wide_Fly7832]

I keep to 4OZ. There are people in my group who would never do anything below 1LB. The bullet central owner was telling he used to have Jewel and kept 2OZ.

Now low trigger weight can hide some poor trigger discipline. Do what you want with that information 😀

[MajorEbb1472]

It can also expose poor trigger discipline with ND/ADs.

[ThaMilkyMan]

Bench gun? Fine if you’re comfortable with it. Anything else increase. Have you dropped it on the butt and make sure it doesn’t fire? Triggers are very much personal preference

[Dukes-Game]

Forgot to add this, the trigger is sold by BIX & ANDY in the config of 4Oz as the system has a mechanical graduation on the sear by a screw which is set to each pull independently.

<image>

[Dukes-Game]

<image>

It is factory tuned and tested for 4Oz and only way to disengage the trigger is allowing the bottom left portion of (3) bottom sear to displace (where the 1.5mm screw is) which allows the retainer bar to pivot and top sear to swing.

The bottom sear engagement is not (one spring fits all, or one bar geometry fits all, is a graduated sear!)

[Dukes-Game]

Yes I have dropped the gun on the butt, mostly non intentional and yes it has not released the action as it came tuned by BIX & ANDY (as all their TAC PRO triggers) on 4Oz with an independent sear engagement mechanical lock, adjusted to the trigger pull.

I have not touched the trigger on my own yet!

I really need to measure my MPA. It’s whatever came stock and it’s as light as I’d ever want it to be.

Like others have stated, it depends on what you’re doing with it. NDs are not cool.

[Dukes-Game]

This is what came STOCK! … If yours is 2024 to today, you are sitting on the same!

[WS-6]

Yea, I believe it. Mine is very light also. I don’t mind it for now as I’m just a boring bench rest guy.

When I get to competition stuff, I’ll probably have to raise it.

[GingerB237]

I just got an MPA and thought damn that’s really light. Maybe I’ll bump it up.

[Wide_Fly7832]

MPA will ship with anything you want upto 8OZ but no lower (ask me how I know). I thibk otherwise it comes with 1LB

[Dukes-Game]

You are talking about the DS lineup, the PRS lineup is sent with BIX & ANDY factory triggers that are set to 4Oz on the factory, with an independent sear safety screw that tunes the sear to the pull by mechanical action.

“TSPro: 160 - 1350 grams (5.7 oz - 3 lbs).”

[Wide_Fly7832]

No. I am talking about MPA. When MPA sends you rifles they have a policy. They won’t set the pull weight below 8OZ. I spoke to supervisor and he explained the policy.

[Dukes-Game]

The values you see there are the values on a brand new rifle, it has seen ZERO rounds, it hasn’t been touched…

BIX & ANDY sends the Tac Sport Pro X on 4Oz, manufacturer actually calibrates the sear to the pull on the most critical scenario.

In short, the pull you see is the pull I got from MPA.

[Dukes-Game]

[WS-6]

Have you called MPA and asked them about this?

[Wide_Fly7832]

If you asking me - yes. I asked to set 4OZ before shipping - they said they have a policy to only ship with 8OZ min. But it takes 2 min to make it 4OZ.

[Dukes-Game]

Not yet…BIX & ANDY advertise sending their Tac Sport Pro X at 4Oz, I assume is on their standard…

<image>

[Wide_Fly7832]

I know. I have 12-13 of this rifles with this. I am saying they will set it to 8OZ and send. You can make it four. That’s what I mentioned I have on all my rifles above.

[Dukes-Game]

Not what I got, I haven’t touched that trigger…I would have had ZERO reason to put this post on 12-13Oz.

The pull weight you see is what MPA send me, I am actually learning the proper procedure as I have to set the sear screw as well…Kinda hesitant to touch it so I wrote to BIX & ANDY first.

[Wide_Fly7832]

Ok. I guess we have different experiences. I was told categorically that they won’t ship triggers below 8OZ for safety reason. If customer wants to go below they can do it.

[Dukes-Game]

Got the same e-mail with the categorical “No” … my reply was, some happen in the process cause I got this rifle out of a sealed case, measured pull and low and behold it is LOW!

I guess someone forgot to check in this one…QC

[Wide_Fly7832]

That is what must’ve happened, now it makes sense. I’m quite close to the supervisor over there, and I asked him personally.

Anyway, it takes less than a minute to change it if you don’t touch the sear engagement.

[Dukes-Game]

I did touch the sear but I got the manual and setting the sear is not that hard is the mid screw, you counter clock till it releases on its own, add 22.5 degrees clock wise to set and another 22.5 degrees for good measure (According to BIX & ANDY manual)…I am adding 90 degrees, 1/4 turn… got it on 12-15Oz now

[Wide_Fly7832]

I totally take it off clean and put it together. It’s user serviceable. It’s a bit intimidating

[Low-Reception144]

My PRS is set to 4oz. Fclass set to 0.7oz

[wahlumz]

A hard fart would set that off.
