40x handstop
 
Anyone have a picture of what a 40x handstop looks like? I think the USMC version is a round aluminum donut style painted black but I don't know what the standard heavy barrel version looks like.

I have a box of handstops and I am hoping one will fit my new 40x HB :cool:

presidentg 12-03-2009 10:50 AM

Here you go. There's also a threaded washer which is under the handstop plate which the hand stop screws into. The raised petals on the handstop fit into grooves on the plate which allows some adjustment.

For those of us who don't have a box of handstops laying around :) any suggestions on where to look to acquire one for a newly acquired (hopefully) 40X?

jbowden 12-03-2009 03:03 PM

Looks like I'm one of those without a box full of handstops. So, this would seem to be a good project for my new lathe. Could someone with calipers give me some dimensions of an original unit? Thickness and diameter and then diameter, height and offset from center of the screw boss would get me going. Great precision is not really needed. I just want it to work.

TIA,
Jeff

:cry: We all went through the hand stop issue 3 years ago. Basically you'll have to watch the gun shows, Ebay etc. as they are very scarce. Most folks didn't have much luck 3 years ago but Hope springs eternal

MiDodgeguy 12-03-2009 03:38 PM

I know CMP sold some in 04. Hopefully they will list a small batch for sale...

Will this Creedmore hand stop assembly work on a 40X?

joe wilson 12-03-2009 04:24 PM

Dont know mkrad (I have a HB 40x on reserve too and am looking for a suitable handstop as well) But if you are considering buying one like you linked to, this one is as good or better and at a much better price. I bought one for my Mossberg and it is really well made. It even has a piece of black felt attached to the side that slides against the stock. You cant go wrong for $42. http://www.mcmfamily.com/images/acce...D-HANDSTOP.jpg

I am looking for a plain round doughnut type as pictured by presidentg.

presidentg 12-03-2009 04:33 PM

I just checked and if your 40X has full length hand stop rail many of the current hand stops should work. My USMC 40X has a short rail, about 7" or so, which requires the Remington hand stop. The current hand stops stud diameters are too large for the USMC 40X. It might be a case where the 722 (earlier) actioned rifles have the short rail and the 700 (later) actioned rifles have the full rail. Can't say for sure but can say Good luck...

MiDodgeguy 12-03-2009 04:55 PM

Where did you find your hand stop?

J.W.A. 12-03-2009 05:04 PM

Pres, thanks for the pic!

Allright, I have one of those in the box! The tag on it reads "USMC only" though. I suspect the aluminum handstop is for the USMC version only?

I dug out my Remington factory parts catalog and it shows the 40 XB (HB) with a wierd shape plastic handstop (they call it the "front swivel block"). I have 5-6 of those in my box also so it looks like I am covered.

I will scan the exploded parts diagram and listing and post it here when I get a chance this weekend.

And before anyone asks (I can sense some of you jumping up and down in your seat), the answer is YES, the extra handstops I don't need I will post in the exchange forum since most of you are in the same boat as I am, except without the box of handstops.

Thanks for everyones input.

Regards,

presidentg 12-03-2009 05:07 PM

My hand stop came with the rifle. 3 years ago the CMP had the USMC 40Xs with sights and handstop for $800. Best money I ever spent.

The one I have is 1.328" in diameter and .756" thick. The center hole is offset and approx. .480" from the center of the hole to the closest edge. The raised flower petal area is .630" in diameter and .030" high. The diameter of the sling swivel recess is .611"-.622" (not exactly round) and
.130" deep.

It is cast aluminum and painted back. Hope that helps.

I ordered a 40xHBSS so I could finally use a stock I bought from the DCM at Perry 15 years ago (10 bucks if I recall). I just got out this stock to get measurements of the hand rail. This stock is for a 700 type HB action (with swept bolt). It has the long rail.

My Anschutz hand stop will not work. The Remington rail is blocked in front by the wood of the stock. The Anschutz hand stop is too long to fit in the recess and also the wrong shape to fit the t-slot.

Handstops with a square or rectangle nut to fit the t-slot should work. I have the handstop that came with my H&R M12. It looks exactly like these handstops. The t-nut is .510" by.450 inches wide and the narrow fits fine in the 40x. The wide fits the Anschutz. The actual slot measures .325 on the rem, .400 on the Anschutz and .330 on the H&R.

I also found these handstops similar to the picture presidentg posted.

By the way, know anyone that has a Winchester model 75 barreled action to fit a stock I purchased at the same time?:p

J.W.A. 12-04-2009 03:02 AM

Rick,

Thanks for the additional info, looks like I ended up with 1 of the 40X type and 5 of the 40XB types. I guess I have to wait and see what the CMP sends me before I can bequeath the extras to my fellow forum members.

PS, The 40XB versions do not seem to be plastic but some sort of bakelite material......

mkrad 12-04-2009 09:09 AM

Jeff,

Please put me in line for an XB type if you are able to let them go.

Matt

Bottom right is your 40X hand stop. The little round one

J.W.A. 12-04-2009 09:40 AM

Hey guys,

I will absolutely share the "wealth" and I will have extras and I will let them go to you guys but not until I get my 40X delivered and squared away. I don't have a good way to keep track of who spoke first (I've also gotten PM's and emails) so let's do this officially in the "parts for sale" forum after the 40X's arrive.

I can list them "CMP style" and wait until you all go to work and are away from your computer so the lucky few who are online will get them (like the USMC rifles) :mad:

OR, I can list them "Jeff style" and place a post about a week before listing handstops the EXACT time and date I will list them in "parts for sale" forum to give everyone an equal chance at posting the first "I'll take it". ;)

I am also looking into casting some replicas of the early 40X aluminum style if there is any interest. I may do a batch of 10 and see if anyone wants them. You would have to find a source for the screw and swivel though. Just a thought.

Regards,

Yep, thanks again Presidentg for posting your original pic. I would not have been able to cull these out of the big box of handstops without your and Rick's helpful information.

I think you should list them Jeff style :).

I have a proposal for you. If you can give me some very detailed pictures of that handstop and dimensions I can draw the hand stop in solidworks (3-D design program - contact me via email if you are interested) and have a local CNC shop cut them, evening including original markings/etc. But powder coating them black would be on everyone else.

Excellent! Proposal accepted, I am familiar with solidworks but don't have it - Email sent.

Thanks to both MiDodgeguy and Jeff.

As a newbie to 40X, it will be a great service to me and, I am sure, many other.

MiDodgeguy and Jeff,

Just another example confirming what I already knew about the caliber of guys on this forum....top-shelf. :GS:
That's the type of can-do collaboration that made this country great. The best to both of you, and keep me informed on your progress. I have a 40X heavy barrel reserved with paperwork in the mail, and with any luck, will be a first-time 40X owner needing a handstop!
Cobra.

MiDodgeguy 12-04-2009 03:02 PM

We will keep you all updated as we progess. Hoping to have something in the works by next week.

mkrad 12-04-2009 03:11 PM

Ditto, thanks for your efforts, guys.

sschrad 12-04-2009 03:59 PM

Thanks Steve

J.W.A. 12-04-2009 05:51 PM

Ok, I sent this info to MiDodgeguy but will post it here as well in case there are some closet machinists out there that want to play.

Also, I am currently sourcing the swivel screw, nut and washer and will post the info when I get a chance.

Orest, sorry for the bandwidth eating pics but it was necessary to get the detail.

Notes:

All dimensions taken on the painted surface (it does not appear to be powder coating). I have access to a paint coating thickness gage if necessary but the coating does not appear to be more than a couple of mils thick.

Since these are cast they are not exactly round and the sling swivel recess hole is not exactly round so I averaged the measurements. The averaged measurements are marked Avg., true dimensions are marked without the qualifier.

The 2 round dimples adjacent to the screw hole are very shallow and I could not easily get an accurate dimension. In reviewing presidentg's picture I noticed his does not have those dimples so it may not be necessary to duplicate them.

I estimated the break edge radius since I only have a set of digital calipers in my desk at work.

J.W.A. 12-04-2009 06:26 PM

It's a team effort since we are all in the same boat. Between 2-3 of us we should be able to crank these things out. I just hope we don't have to make 800 of them to cover all the CMP rifles..........:eek:

MiDodgeguy is actually doing the tedious work with the 3D model and "g" code, I got off easy with pics, paint and screws ;)

blitz10 12-04-2009 07:58 PM

Y'all are good. Every one has their specialty. I can't do much more than run a spray can of Krylon. I ordered a USMC and then this morning ordered a heavy barrel, just couldn't stand it.

Well, since you obviously don't need 2, I'll take that old USMC version off your hands.......:D

I recieved my NOS assembly today that I had ordered from a hole in the wall gunshop I found. Total was $59.60 to my door. I told the guy to let me know if he can get any more - he did say it was a possibility.

If this is really happening I'd be in for a round one to fit my
std bbl.
Just let me know how to get one.
