Slide Racker for MKIII

[Steve Koski]

My 10 year old son wants to shoot this gun in competitions, but he can't rack it if the hammer is down. It is fairly stiff, even my wife has a bit of trouble. Solution - Add a slide racker so he can get a better grip on the bolt.

The slide rackers already in production don't work for the MKIII (I asked). So, I'm thinking that machining up some basic shape for a slide racker and drilling/tapping the bolt should do the trick. Here's the rub: I'm no machinist. I'm not even a machinist's mate third class.

I dont mind paying for someone's time & troubles. I can mail you the bolt and you can go nuts on it.

Here's the raw gun with the bolt closed.

Here it is with the bolt open, top view. There's a fair ammount of "meat" on the back of the bolt.

Here is a link to the MKII bolt racker - that won't work with the MKIII.

If no one else can take care of you, I know a few machinists and have access to full scale machine shops. Be after the first of the year before I can even think about it though.

[MONTEGOD7SS]

Sell it and get a MkII cuz loaded chamber indicators reside in the 7th layer of Hell alongside S&W locks.

[MakeMineaP99]

I agree.

Wait, I don't agree since Monte and I never agree.

[AdamN]

Does he holster the gun? Just wondering how far the "racker" could stick out.

Im sure I could do that, You want aluminum, stainless?? Just bolted to the rear of the "bolt"

[AdamN]

+1 with Monte, Im a big Mark II fan

[ISUSteve]

Koski, what about using a piece from a countertop connecting bolt?

Then drill and tap for a small bolt.

That would be an easy, DIY project. When he gets old enough or you get tired of it, just unscrew it. You'll be left with a hole, but you'll get over it.

[Steve Koski]

Adam,

Thanks much!

He will holster the gun in an Uncle Mike's kydex holster that doesn't hold the gun very snugly to the body. I'm not concerned about the extra width.

I imagine it should be reasonably light to keep from changing the weight of the bolt too much. Aluminum? I suppose there is some risk of it breaking after cycling a half a jillion times. Whatever material you think is best.

[MakeMineaP99]

I'd go 304 Stainless or another stainless alloy if you don't have any 304 on hand...

I am thinking of buying an El Camino.

[BigSlick]

Oh hell yeah, El Camino an a nice haircut an you a get a lotta trim

Don't be mockin' the El Camino. That's a classy ride.

[VN350X10]

Steve, why won't the MK II racker fit the MK III ?
Aren't the bolts the same size in the "wing" arera ?
They sure look to be similar.

[Steve Koski]

Unk,

Apparently the angles are different and the Power Custom MKII bolt racker DOES NOT work with the MKIII bolt. Several websites selling the Power Custom racker said this and...

A GP lurker emailed me and said he tried it - no go. He did say that one solution is to put a MKII bolt (with or without racker, I don't recall) in the MKIII, and either machine the extra notches in the bolt to accomodate the MKIII LCI, or remove the LCI parts from the MKIII receiver.

Koski

[MullahElRon]

Be a lot easier to buy a MKII.

[VN350X10]

File time......

[MONTEGOD7SS]

Ezactly like I said in post #3. Sell that demon spawn and get a MkII.

[Steel Talon]

I like this idea! But make it MO BETTAH -> Find a miniture 8 ball and send it to Adam for his magic. Your son will definately be pimpn' on the firing line :slick:

Yeah, if I knew then what I know now...

[MONTEGOD7SS]

Only been three weeks, you still have time to repent and make things right.

[AdamN]

Well if the mail man will get his stuff together Koski will have his racker in time.

The first rendition lookled like this.

He was a little worried about any extra weight causing problems so I put the nice sculpted model on a serious diet and cut/milled off anything I could and added a few lightening holes, ending up with this.

http://www.glockpost.com/forums/picture.php?albumid=58&pictureid=455

[MakeMineaP99]

What is the weight of the addition as manufactured?

[AdamN]

Its made from 7075 alum, was close to 20 grams, which was about 15% of the stripped bolt weight.

After I lightened it up it was 10 grams, about 8% of the stripped bolt, hopefully not enough to matter.

[MONTEGOD7SS]

He'll just have to shoot Velocitors now, no biggie. :)

[AdamN]

True; he's Koskis boy so Im sure he can handle the Major PF 22 stuff:2gunsfiring_v1:

[MakeMineaP99]

If Koski runs into problems, he'll just have to put a suppressor on the pistol to increase the back pressure.

[BigSlick]

Man ANeat, dat is one cool lookin piece a work right there :thumbsup:

8% won't make any difference at all with any brick ammo, maybe with a Colibri, but even then prolly not.

I bet that lil piece can be polished out real nice an it a look factory as can be.

Custom for sure ;)

[AdamN]

I didnt have a whole lot of time to try and dream anything up. Basicly that is what Steve wanted, and if he decides to take it off the two small holes wont be an issue. You could always put in a couple of stainless allen head screws to fill the holes.

I think cutting a dovetail and using a one sided racker like on a 1911 would be another option but might be more of an issue with it removed.

Ive made a few like this in the past and Brownells sells this one that fits a standard dovetail.

ANeat, that's a fine looking piece of equipment you made there !

You do nice work. And if you "tuned" it just right, it might whistle Dixie while shooting !!

[Steve Koski]

The mailman screwed me again today. No matter, the boy isn't too hot on shooting in 18°F weather tomorrow.

[MakeMineaP99]

Whip. Out here we shoot in sub zero weather.

[VN350X10]

Graphite in the G20 instead of oil.
Tested at -15*F, I quit before the gun wanted to.
10MM makes a real sharp "KRACK"! at that temp. Echos real nice.

If the original design doesn't work, I would suggest cutting a dove tail on the back of the bolt and installing a similar piece to the shown, however, I would have an actuator on both sides. This will require some machine work, the piece will have to be turned from round stock and then milled, but it presents a lighter solution in the event the original does not work.

I "talked him down." You don't really wanna go shoot in the freezing cold tomorrow do ya? You'd rather stay home and play the new Wii, right?

Of course I'm going, and I did my best to humiliate my pansy neighbors who are chicken to shoot in the cold.

[VN350X10]

Great time to shoot the Wii !

Being from upstate NY, I'm built for the cold. There's nothing more invigorating than stepping outside in the morning and being able to taste the cold.

[VN350X10]

You're not tasting the cold, but rather the flag pole that your tongue just froze to !

You could shoot a 500 mag!

[jimruger9]

Im in, i didnt spend 4 hours out in the cold today setting up for nothing.

[MakeMineaP99]

My deepest apologies. Kick Koski's ass for me. ;)

[jimruger9]

Just hoping it wont freeze off. Gonna be a first for me a steel challange type of match. not any movement just fast small steel shots.

[Steve Koski]

Small? Those targets are 8" across, or bigger!

Yea thats small compared to shootin the turtle:2gunsfiring_v1::animlol:

Adam,

That thing friggin' ROCKS! I haven't had a chance to fire it yet, but my boy is totally thrilled with it, as am I.

[BigSlick]

Nice :thumbsup:

Let us know how it shoots with the extra weight on the bolt. I can't imagine something that lightweight having any effect, but I am curious.

I have a MKIII that prolly needs the same thing done to it for when youngins go with me ta shoot. Mine loosened up some after a couple bricks, but a couple a nephrews still have some problem wit it

Especially cool dat ya can fill da holes wit a allen screw if ya don't need da racker.

Hella cool if ya ask me, look good too

[AdamN]

Well good; I was getting a little worried about it getting lost. Im glad he can work it. Id say a little bead blast and some black bake on finish wouldnt hurt it but I would shoot the heck out of it as is

[Steve Koski]

Most of my guns are "working guns." The finish is actually a lot smoother/better than those pictures show. The camera flash seems to bring out every tool mark.

We're going to shoot it in Phoenix in a couple days. I'll let ya know what happens.

Thanks again Adam!

WORD! Fort Drum a cold mo fo back when....

Adam & Steve......
Looks like nothing that couldn't be cured in a glass bead cabinet to give it a uniform "frost".
Fantastic job Adam !
You just might have come up with the newest useful accessory for a Ruger !
Might want to check into having that puppy CNC'd for mass production.
I'd be willing to bet that guys running scopes would be interested.

Adam,

The test run of the slide racker (400 rounds of Federal bulk pack) worked like a champ. Zero malfunctions. Thanks!!!

Thats great Steve, I hope your boy gets a lot of use out of it.
