Impact Precision Actions

#701
The trigger timing is a neat feature, which is part of the so-called "magic" of a Impact action. PRS shooters couldn't spell trigger timing until the Impact came along. One of the main reasons why an Impact is said to "feel" so good in comparison to other actions - because people didn't have triggers timed to their actions prior to running an Impact.

If you run a BnA Tacsport trigger, you can time your trigger to any action with the benefit of the sear engagement and the differing sear heights available. So you can turn that TL3 into a pretty slick running and timed machine with something like a BnA - no gunsmith work required. You can dramatically improve/optimize the trigger and bolt interface with a BnA trigger, making pretty much any top tier action have incredibly light bolt lift and close. My Mausingfield, Defiance Deviant and LP Fuzion with BnA triggers are some pretty damn awesome feeling actions with light bolt lift and close, I'm not losing out to an Impact on "feel" with any of my actions. I changed my triggers out from TT triggers to BnA triggers and it's the single smartest gear related decision I've made in this sport.

If you want to run something like a TT trigger which has a set sear height, then the hanger on the Impact is certainly a nice feature. The short amount of time I had a TL3 action, it was paired up with a TT trigger and definitely could have benefited from trigger timing. The bolt lift and close was much heavier then necessary, and the TL3 when properly paired up with a trigger has some really light bolt lift.

Between the TL3 and Impact, it's all preference. Between the two, I would personally take the Impact as I hate the slop in the bolt of the TL3. The TL3 has some great features and great CS to back it up. Pair it with a BnA TacSport, and bolt lift and close will feel every bit as good or better then an Impact once you get it dialed in. Changing barrels on both is easy - every rifle is a "switch barrel" rifle. Both have the benefit of prefit barrels being available, and with gunsmiths being able to spin up barrels without having your specific action in hand. Both run well in adverse conditions.

At the end of the day, it's more or less a preference of CRF over push feed, and changeable bolt heads vs having to change out the entire bolt body assy. Neither is overwhelmingly better than the other.

Hell yeah man thanks for the info, these are the small details I’m after. I get it that it’s pretty much personal preference when it comes to choosing between the tier one actions but it’s a nice chance in pace hearing the details, other than the typical responses like “action A felt smoother than action B” or “company A has better CS than company B”.

Glad I could help - there's a lot of rhetoric and hyperbole when it comes to peoples responses on actions these days. I agree that just posting "action A feels better than action B" doesn't help much. A lot of cheerleaders these days trying to justify their purchase by seeking confirmation bias. On top of that, the same action can feel pretty differently based on how the trigger is setup and interfaces with the bolt, it makes a lot bigger difference than people realize - this can make it hard to distinguish between some of the noise online. People may think that action A "feels better" than action B, but that could simply be a function of the trigger on action B not properly optimized for the action.

Thankfully, there's a lot of great options and its hard to make a bad choice when you get to the top tier actions.

FWIW I run 6BR in my Impact out of ARC mags with no spacer kit and have done so for matches since February. I just tap the mag to ensure the bullets are seated all the way to the rear of the mag and I have (knock on wood) had zero problems with feeding from the magazine since first trying it out. One person that I brought out shooting with me had a problem when trying out my rifle, but considering the problem was a double feed I don't think the issue was due to the magazine.

Bit of a different setup but it's finally done.

I agree with trigger timing making a difference on how good a actions runs. I have defiance deviant, impact, Mausingfield, and nucleus and they all went from trigger tech diamonds to bna tacsport pro and when you get your sear engagement set properly they do run noticeably better. Out of those actions the impact is the best feeling, but not by much. Also proper magazine feed lip adjustment makes a big difference. When everything is set right you can barely feel the action pic up a cartridge.

What's the timeframe for release? Is it fully coated? They planning on a long action? I'm in the market and wondering if I should just wait.

TS Customs unboxed one on Facebook the other day, so I guess they're starting to show up in the wild. I wonder where folks will draw the line on price though, those are some expensive ounces at $1950.

If anybody is interested in watching how it runs, here are two stages from a recent match.

About 300 rounds through the action. 6mm Creed with factory 108 Hornady. The 5 round accuate mag was giving me a bit of trouble and MDT 10 rounder runs great.

Excuse the poor shooting and random footage in the video. Only 2nd match this year and 2nd year doing this.

Second stage starts around 2:35.

I’ve been playing with triggers and my impact over the weekend (TT diamond and BnA) the bolt lift feels good but it has quite a hitch on close(maybe that’s normal)!
Way more than my defiance,gap,borden or bighorn.
I might see if I can order a different sear for the BnA as any adjustments I tried were of no gain.

I have the same thing. Let me know if you are able to get it to go away or decrease.

I was thinking this might be the case after trying a few different triggers.
Guess I got sucked in by the 14 pages on how “smooth” these actions are.

When people describe Impact as smooth they refer to sliding the bolt back and forth. With the right hanger and a bix n andy trigger with the sear engagement set properly the Impact runs like butter and only gets better as it breaks in. If you want to feel nothing when you close to bolt Borden actions are the only action out of the box that will do this but the trade off is a heavier bolt lift. I believe even the Borden SS6 is timed neutral like most other actions for this reason.

Or something like the Mausingfield with it's 105/-5. Mine has incredibly light bolt close, with a bolt lift that's negligibly more than most 50/50 actions.

However, huge part of how an action "feels" is based off of the interaction with the trigger. Timing a trigger does wonders. You can pair the best so-called "feeling" action in the world with an improperly timed trigger and it will feel like shit.

Impact Precision actions are timed pretty close to 50/50, compared to most actions that are closer to 100/0 or 105/-5. Instead of all the cocking being done when you open the bolt, it only does part of it when you open the bolt and the rest happens when you close the bolt.

This is why an Impact Precision has such a light bolt lift compared to everything else, because they are only partially cocking the firing pin when you open the bolt. It's also why an Impact Precision feels heavier (or as though there's a "hitch") when you close the bolt, because it's doing some of the cocking of the firing pin during the closing of the bolt.

Other actions do no cocking during this stage or will even slightly de-cock the firing pin here, contributing to a lighter feel when closing the bolt.

Basically you're trading a lighter bolt lift for a little bit of resistance when you close the bolt. It's a good trade in my opinion because you have more leverage when closing the bolt than opening it anyways, and it's something I hardly notice when running the bolt quickly. Others dislike this and would rather have a 100/0 or 105/-5 action that has little to no resistance when you close the bolt, at the expense of a heavier bolt lift.

Finally got my Impact Valkyrie build all sorted out and it’s a smooth shooter for sure. The MDT modified mags from CH Precision worked really well on a JAE chassis but not so well on the Manners. I tweaked a regular AISC mag and ordered a Primal Rights 6br conversion and it should feed fine as I have done this with an Axiom build.

The "hitch" is the trade off for more primary extraction than most other receivers. The primary extraction doesn't let the bolt go all the way forward before you cam it over, the plus to the design is obviously the extra primary extraction.

The “hitch” on closing is on all of the impacts I have cycled. It kinda of springs the bolt home. Part of the reason the action is so fast.

I really hadn't noticed this on mine but i've been running a tempest for so long that i'm used to forward pressure to close. Impact is a solid 2-lug it's smooth and i'm eager to see what it's like if i can get it broken in. Honestly i feel like the mass of that bolt plays a very large part in the perception of it's smoothness. The thing just seems to have much more momentum than any other action i've run. My personal tempest still reigns for me as the smoothest i've put hands on, but the impact is thus far my favorite 2-lug. And honestly while i was not terribly wild about my TL3, i love my little brothers origin. It's still kind of "loose" and needs to be run on axis but running his 308 is very fun with that action.

I had a defiance before my Impact and the defiance was Smoother and tighter but the impact is faster. The defiance was DLC’d by the way.

the impact has the right amount of slop IMO.

Just to confirm... will an Impact fit in a Manners stock that has been bedded for a Surgeon 591? Aside from the bolt release being round instead of square.

I don't know for certain,
but other than what you've noted about the side bolt release shroud shape.

I think you'd be good to go at:
a) bolt handle clearance
b) recoil lug area - a smidge thinner on the 737 vs 591.

My doubts would be where the trigger connects to the action,
where the 737 has a hanger that requires more clearance than the 591 which pins direct to the action ( no hanger).

And I don't know how the ejection port would align or if that is of huge concern to aesthetics.

Thanks, I should have added that this would just be temporary while I wait for a stock from Manners specifically inletted for a 737r. In that case I'm not super concerned with aesthetics, mostly just function so I can shoot it.

The tab for mag catch latch need to trim a little..i filled a little.so basically the oal legth of the mag with mag catch is several thousands longer that internal oal length for hawkins bottom.its easy fix
