This 'sliding' safety on the "INTERARMS MARK X" / 'whatever' action ---
Does it block the sear/trigger and/or lock down the bolt when 'on-safe'?

it's a trigger block. It does not lock the bolt and does not remove the firing pin from the sear as the M-70 does.
IMO it needs to be replaced.

well, since I haven't seen any mods that remington might have made, I'll assume info on the markx/interarms/charlesdaly will suffice

IIRE there's an interesting cut-out in these actions, when the safety is moved. I haven't kept the factory trigger in long enough to see the neat functionality of the safety.

These have been replaced for sliding timney's, for the most part, which have exactly that same "aint locking the bolt or or firing pin" issue that every other non-bolt locking safety has.

to be clear, the factory mauser, the wincheter 3 position safety, and very few others actually operate on the bolt and firing pin...
timney, remington, every slide safety mauser, browning, weatherby, etc etc etc all work by blocking the trigger, the trigger's sear, and in the case of ruger 3 position, by locking the trigger and then a detent/indent to lock the bolt... even the rsm.


here's some good advice.. don't work the bolt with a finger in the trigger

Didn't the Mark X s lock down the bolt ?

My Whitworth sure does......

Vapodog,

I do believe the side safety on these did lock the bolt down.

They need to have the 2 or 3 position mod done to them; that also locks the bolt down and blocks the firing pin.

Jim...this is definitely not the case with my zastave magnum action. It is as I posted.

vapodog,
I am certain you tried it aleady, but if you take the action out of the stock, i am certain you'll find a longitudinal cut, about 1/16" on the righthand (from teh top) side of the action... that was there to block the bolt.. with the original trigger, of course

When you slide the safety back the tab locks the bolt by blocking the third lug from rotating. The same slide has another section that passes under the rear of a conventional Mauser trigger to block it from movement. They don't block the firing pin. But IIRC on my 375 (which was a WHitworth barreled action), there was an aftermarket adjustable trigger assembly that may be what Vapodog is referring to. It may have been a Whitworth part and not normally found on Interarms versions until they bought all the extra Whitworth inventory.

Jeffe, I'm, human and can be wrong and will post a correction when that is the case.

this photo does not seem to show the cut.

It's a 375 H&H length action from (barf) Chas Daly.

It took some work but will make a respectable shooter I think. That said, the safety does not lock the bolt.

Vapo, the cut Jeff is referring can be seen in your picture just forward of the trigger assembly pin. That is the same trigger that came on my 375 and not at all like what came on the bulk of Interarms Zastavas. I think it may have become standard issue at some point before Charles Daly started bringing them over.

Here's the "standard" trigger and safety:

so the correct answer is that some lock the bolt and some do not.

And of course we don't know what Remington is going to offer us.

This much I'd bet on.....they made a change on the M700 to not lock the bolt by placing the safety on because of safety concerns.......it had to have the action open with the safety on.

This makes the case for the tried and true three position safety.

Sadly if one buys a completed rifle and attaches a swing safety he leaves a gap in the stock like this on my FN JC Higgens

Vapodog,
have a look at your pic again, and work your safety with it out of the stock.. it LOOKS like it has it all there, to block the safety.. but may not be funcitoning either due to factory misalignment or the stock doesn't cut it back enough to allow it to engage or it's a different trigger (from the factory) but with the same cut in the action

area outlined in red, bar in red, slot in blue..

i can be wrong, and certainly have been before,

well....not to be argumentative but there is definitely a cut.....but no block as my reddened stamping shows. I bel;ieve you're seing the body of the trigger assy as a block but in this photo I've outlined the moving safety stamping and absolutely nothing slides thru the slot.

I have one of the first ever Daly's in a barreled action (besides the ony in the pic and that trigger is the very same way. No block

I have a couple of old Mark X's. and a couple of Whitworths, all of them lock the bolt down. I have one Mark X newer with the cross bolt floorplate release, it does not lock the bolt. I have a newer CD 7x57 that doesn't lock the bolt down either. By the way, while the Ruger doesn't block the firing pin, it does lock into the striker when all the way back which prevents the bolt from turning and also from the striker coming forward. To me this isn't much different than a Mauser safety which pulls the striker back when on safe. Is this correct?

Jeff, I don't think on that model trigger they ever blocked the bolt. BUT...all the receivers are cut with the same slot to accept the slide that does lock the bolt.

In that picture, you can see that the slide does not project any farther than the screw that holds it to the trigger. Just like a SAKO trigger. It never went up into the slot. Mine is the same way.

It makes one wonder why they waste their time milling the slot!!!!!

and I think this is how disagreements on AR should go... couple pics, a little discussion, and we find that most folks know that they are right, just the guns change!!

I am in.. not all of them block the bolt!!

Is there a source for parts, in case one were to want to make the bolt lock down ( or not ) ?

Every MKX or Daly I have seen in the last 25+ years has had the slot. The early MKXs lock the bolt down on Safety. The later MKXs didn't lock the bolt nor do the Daly's and my guess the 798. If you want the bolt to lock get an old MKX trigger. Or have someone alter the safety slide. Seems to me they stopped locking along about the time the cocking piece was altered for faster lock time.

I'd highly recommend this type


or this type.


Both lock the bolt but this last one allows the third position and you can open the action with the safety on or lock the action with the safety on.

the first type is about $100 and the three position is about #250

Further both have the advantage in that they don't block the trigger. Both remove the firing pin from the sear....in other words they disconnect the firing pin from the firing linkage and the firing pin cannot fall unless some serious heavy force breaks large pieces of steel......it ain't going to happen.

I appreciate all the detailed photos and descriptions.

My other rifles have the 2-POS safety in the same location as the '798' and I want to maintain that location throughout the bolt-actions I have.
Changing to a 3-POS safety is not what I want to do, but I appreciate why it was mentioned.

Apparently, by getting the '798' I will need to have some gunsmithing performed in the process of making it a .458 LOTT that has a bolt-locking safety...

Let's see:
Barrel reamed; magazine box altered; different trigger/safety parts; bbl.band swivel; front and rear sights; new RECOIL PAD!; etc.
Sounds like FUN.

Numrich may have the old trigger parts.

I am just guessing but the slot is a standard production set up and they probably still sell the old trigger style in other parts of the world that don't have the USA trial lawyer situation or those markets just doesn't ask for an adjustable trigger assembly.

FYI.. My mini action has the provision for the bolt lock too.
