~~NEW~~ Ruger Mark Recoil Spring Assembly

[SGW Gunsmith]

Sarona Gun Works LLC is now offering a variable rate recoil spring assembly for the bolts involved with the Ruger Standard, Mark I, II, III, IV and 22/45 .22 caliber rimfire pistols. The kit below has springs calibrated for .22 rimfire ammunition at low velocities, around 800 to 1050 FPS, mid-range velocities, around 1100 to 1280 FPS, and then the higher velocities, around 1300 to 1450 FPS.



There are extra, single, recoil spring assemblies for sale: SEE THE ON-LINE STORE



These recoil spring assemblies are made much better than the factory assemblies. The "yoke" whereby the bolt stop pin goes through is now a machined part rather than a stamping that's crimped into place. The front end of these assemblies is not "staked" into the crescent shaped plate that fits into the slot on the front end of the bolt. There is a small screw that goes into the front end of the recoil spring rod, so that changing the spring is an easy task that does not require recrimping of the front end of the recoil rod.

So, what is the reason for getting one of those assemblies? I have a 1972 Mark 1 with about 50-60,000 rounds through it, with ZERO malfunctions and no apparent spring weakening. I fail to imagine a justifiable purchase. But, that's just me (and maybe a whole lot of other people). They look purty, but......

The low power aspect intrigues me, but then I have wondered about making a dedicated .22 short MK II.

The low power aspect intrigues me, but then I have wondered about making a dedicated .22 short MK II.

Back in the day, Volquartsen sold a light weight bolt and proper magazine so that .22 Short ammunition could be shot & cycled from the factory Ruger Mark I & II pistols. I sold several of those conversion kits to bullseye shooters for their Ruger Mark pistols. Some just don't seem to realise that "variety is indeed the spice of life". So, if you do get a Ruger Mark pistol converted to shoot .22 shorts as an alternative, please post your outcome here.

I experimented for quite some time lightening a Ruger Mark pistol bolt in an effort to get the pistol to fire and cycle CCI Quiet ammunition. I couldn't safely get the bolt down to the weight I wanted it to be at, and had to come up with a different plan. Volquartsen sent me a prototype bolt they happened to be working on, specifically for that purpose, to shoot and cycle CCI Quiet ammunition. So, it seems there are more than enough Ruger Mark pistol owners, that have graduated from the Ruger Mark I, into the Ruger Mark II, III, and now the Ruger Mark IV and 22/45 pistols that there is some interest in experimenting with various .22 rimfire rounds with velocities that run from 710 FPS to 1640 FPS, and, doing some thinking outside of the small box others have imprisoned themselves in. The bolt in this pistol (below) weighs less than half of what the factory Ruger steel bolt weighs. As was mentioned earlier, this pistols fires, feeds and cycles CCI Quiet ammunition very well, with low noise and good accuracy. With a suppressor attached, it's scary quiet.



The recoil spring kit is for forward thinking Ruger Mark pistol shooters who want to experiment with the myriad of available velocities that are now avaiable in .22 rimfire caliber. Those who enjoy the doldrums of "same old, same old", as long as you're happy.............................

Well, for those who like to experiment with springs, it is neat to have a spring guide that comes apart. I've personally never seen a recoil spring that was worn out even in older MK I pistols, but cool is cool. It is interesting that the listing for the spring assembly on the SGW site says:
"...to handle the bolt return of the variation of power now involved with .22 rimfire rounds currently available."

Sounds obscure. Surely this does not mean that a special spring will self-adjust to a variety of loads?

Good grief!

I can say due to my experience in this and other shooting sports there are those that do not and will not experiment beyond what they have read or are told. That's fine, but just because you have no vision doesn't mean others don't. All I can say it is good some people experiment or we'd still have wheels with four corners.

"...to handle the bolt return of the variation of power now involved with .22 rimfire rounds currently available."

Sounds to me like someone is paying attention to all of the NEW subsonic, no powder, low power, low noise rounds and how some cycle a semi and some don't. I'm thinking about expanding my .22 short idea to using Aguila Super Colibri's. I have used these ultra quiet rounds on vermin in the neighborhood and would like to no have to single fed them.

Yes. It will even tell you to what degree it is self-adjusting. :wink:

It's sorta funny. Volquartsen is the company that puts out this spring kit, so I thought I'd let some of the folks here in on that news. Why are they doing that? Because of customer request, from some who would like something like this spring kit to be offered. And, if you compare the recoil spring assembly rod that VC now offers to the Ruger Mark I, II, III and 22/45 Ruger factory recoil spring assembly rod, you'll soon see that it's made much better.
Seems there's alway that "select group" that FEEDS on negativity so their day crawls along much better for them? I really don't care if anyone doesn't like this idea, and won't buy it. No sweat off my BOYS. Those of you who don't think you want this kit, fine, nobody says you absolutely need to have one of these to make your day even more worse than it is now. :shock:
