#4064 need help finding a cocking piece for my 591 bolt

Posted by JFK52 on 15 January 2016 - 01:53 PM

Numrich has the entire striker assembly of which the cocking piece is one part. I bought the complete 591 striker assembly for $38.00. A lot more expensive than the cocking piece which sells for $6.60. Only no one has the cocking piece in stock. Since my 591 is my daily varmint rifle, I am glad to get in back into service when the parts arrive from Numrich.

#4106 Interest level in new plastic magazines?

Posted by Gary W on 13 February 2016 - 11:18 AM

I apologize, I meant one of those copy machines that makes plastic parts. I know nothing about them but have heard that they work pretty good and are coming down in price. The guy said you can apply a hardener for extra strength.

#3377 Bolt installation tip--eliminate the aggravation...

Posted by Issa Akhbar on 26 March 2013 - 08:29 AM

Most already know this, and I'm really not trying to be a smart-onager, but for those still fighting with the aggravating tendency of the bolt head to roll over when installing it in the receiver....just point the bolt straight down, align the slots, hold the rifle muzzle straight down also, then slide the bolt into the receiver. The bolt head can't roll over if gravity is working for you instead of against you... :D

#2313 Here's my 591

Posted by autoknife on 11 March 2012 - 12:34 PM

Picked this up years ago at a local gun show for a song. I love the wood and finish and that it doesn't have a mark on it. To be honest I don't think it has ever been fired so I need to find a beater I can shoot.

#2298 damage from my 5mm

Posted by Matt5MM on 03 March 2012 - 07:32 AM

The scope I am using is a Nikon Scope Prostaff 3-9X40. I know its a center fire Riflescope but I went through about 6 differnt scopes before I just slapped on this one. BSA, Bushnell, Leupold and other Rimfire scopes just didn't get the grouping I was looking for. I had this as a back-up for my 7MM and just got so frustrated that I just put it on one day and took it to the range and low and behold I was shooting 1/4" 5 shot groups at 75 and 100 yards. Funny thing is that I won 50 bucks that day from a guy shooting a 17hmr. He asked me what I was shooting, afterwards he started poking fun at my 5MM (He had never heard of it). We shot two 5 shot groups one at 75 other at 100 yards and the tightest group would win the money. He was shooting a Ruger 77 with Elite 3200 on it. I smoked him. I knew then this scope was the one.

Can anyone tell me if there is a way to view this so I don't have to scroll every page to the right??

I've seen this with some other postings that seem to be oversize.

#4036 Resurected after so many years

Posted by sledz on 02 October 2015 - 01:31 PM

I bought my 5mm as a 15 year old in 1972 new at a local Coast to Coast hardware store in Iowa and for Christmas my Dad bought the Weaver cross dot scope that I put back on it. I used it for several years and was a crack shot with it! Big feral cats, opossums, gophers, raccoon, fox, dimes and pennies you name it! Rabbits were especially fun.

Well a year ago I found out about the new ammo being made and bought some and after 40 years it's back! So exciting to shoot this again. I stumbled on this forum and I am glad there is a following. I had no idea the prices for these are so high, it just sat in my case for literally 40 years and I just assumed it was a boat anchor.. I do have a box of original ammo that I never did shoot that probably 35 years old..!

#3654 Recall info from back in the day on the 591

Posted by REMNANT on 12 January 2014 - 03:44 PM

I hope this helps,

The original design for the fully supported chamber, was created so that the gun could be easily cleaned, and all parts were made removable. There was a small sheet metal cover on the left side of the receiver, which could be pried out, and the retainer for the extractor, as well as the spring and guide, could be removed and cleaned and oiled. This left the extractor loose, on the inside, retained by the bolt, until the bolt was opened and removed, at which point the extractor merely fell out. This seemed acceptable at first, but then people started thinking that it would be easy to leave the extractor out completely, and fire the gun, which would blow a large piece ot the case wall out, and create all kinds of havoc. It wasn't long before it was back to the drawing board, to get something that was not removable in the field. This led to the riveted unit, which became the standard configuration. Unfortunately, some guns had been shipped with the original configuration, and every effort was made to retreive these, and retrofit them with the new design. I think only a small number got out with the original setup, probably less than 100, but that is only a very rough guess. I doubt that any 592's were involved, since that model was a little behind the 591, in release. I forgot to mention that, in addition to riveting the extractor in place, the second, ugly cover, with the 4 screws was added, to prevent loss of the pressed-in cover, as well as prevent gas escape, if everything else failed.

Both the 591, and 592 were late to market, compared to plans, both because of the extractor redesign to accomodate the high pressure rounds, but also due to the rim diameter change. When we began to get case failures, with the original chamber design (slotted as on the .22), the first move was to increase the cartridge case wall thickness. This gave a stronger case, but by the time the straight drawn case was upset to form the rim, there was very little space left in the rim for priming mix, and we began to get misfires. Then the rim diameter was increased by .015 inches. This solved the ignition problem, but now we had to get new chambering reamers, and the magazine for the 591 couldn't take the larger rim, so the molds had to be modified for the Delrin body and side, which were welded together. Also the brass and steel magazine tubes for the 592 had to be made slightly larger, which took more time. The original rim dia was about .312 max, and the final dia was about .327 max. These are the chamber diameters, and the actual cartridges typically went .302-.308 on the first gen, to .316-.322, on the final production.

#3603 Remington 592/591 Trigger

Posted by Magnum on 28 October 2013 - 05:17 PM

I purchased and installed a Timney 788 trigger on my 591. Huge improvement. I don't have to give so much concentration on how I pull the trigger (though good practice).

I did have to modify the safety lever and removed a small amount of material from the stock to clear the bend in the lever - nothing you can see externally. I haven't officially checked the pull weight. It's adjustable and would guesstimate it at around 1.5 #'s after I lightened it up.

I may modify the original to compare, but doubt it'll work as nice as the Timney without some major TLC.

#3419 Petition to Remington to produce 5mm ammo

Posted by reelman1 on 21 April 2013 - 03:17 PM

Once upon a time (how most fairy tales start) Remington and Aguila had ownership relationship and then had a kissing cousin relationship (maybe even closer). It's a pretty good bet that Aguila/Centurion got the 5mm tooling from Remington, and that is the ONLY reason that we have newly manufactured 5mm. Probably doesn't hurt any that Lil Gun came along in the mean time, or that Eley provided a higher energy priming compound.
Pretty much conjecture on my part but I don't think I am far off from what I have heard and putting pieces together and asking a couple detailed q's that weren't answered directly.

You will not have a problem surpassing the 17hmr in performance and distance. Where as I strech my 17hmr to 150yds I have no problem shooting PD at 200yds. It will not be in the leage of your 222 CF round, but its the best RF to this day.

#2822 M591 Trigger Work?

Posted by Wildcat Junkie on 01 October 2012 - 05:24 PM


After stoning the sear engagement surfaces & getting the pull wieght down to 4 1/2#, I did some shopping @ the local (old fashioned) hardware store.

I couldn't find the exact diameter spring as the original. After rummaging through some drawers in a back room, I found a spring that, although slightly bigger in diameter, would fit within the trigger housing. We picked through the springs & found 2 that were ever so slightly smaller in diameter than the rest.

I bought 2 @ $1.09 ea & with some 4-40 screws, a 4-40 tap & a #43 drill bit, my total bill came to just over $7 including tax.

Here is a picture of the spring as I bought it on the left, the OEM spring center & the spring length that resulted from trial & error trimming/fitting/trying on the right.

Posted Image

I widened the notch in the sear ever so slightly to the rear to allow the new spring to snap into the notch & stay there.
Posted Image

After studying the design of the trigger, I came to the conclusion that a sear engagment adjustment would be problematic. The safety does not block the sear, it blocks the trigger. I did not feel comfortable tampering W/that sort of arrangment. There was no slack between the trigger & safety in this particular trigger assembly & the sear engagment was not very deep anyway. I could never detect any creep in the break so I decided to forego adding a sear engagement adjustment.

I did however, drill & tap the trigger housing @ the lower front for an over-travel adjustment screw. The location of the bolt stop requires that the screw be located very low in the front of the housing. The loaction is very close to the pivot point of the trigger. I decided to angle the over-travel adjusting srew upward to allow it to engage the trigger further above the pivot point & also to allow clearance for the bolt stop.
Posted Image

I trimmed a 4-40 socket head screw to length & pointed the end so that the threads would not become damaged from contact W/the trigger.
Posted Image

The screw clears the bolt stop in both the up & down positions.

Posted Image

It can also be accessed W/O removing the action from the stock by removing the trigger guard.

Posted Image

So now let's discuss the working of the spring length & sear engagement surfaces.

Earlier I had achieved a 4 1/2# break by merely stoning/polishing the sear engagement surfaces.

Even after trimming the new spring several times to a length/installed tension that I felt was minimal for safe operation, I had a 3 1/2# trigger break. Still above the desired 2 1/2 -3# range. Just for kicks I re-installed the OEM spring. That gave me a 4# break.

Reducing the spring tension further was not a safe option & it seemed to not be reducing the break weight proportionately. I decided that stoning the angle of the top of the trigger sear engagment surface was the key to a lighter break wieght,

I ever so slightly stoned the sear engagment surface on the top of the triggger in a downward direction, perhaps 1* or 2* @ most. After several strokes, I re-assembled the trigger in the housing W/the new shortened spring & tried the scale on the break. W/O the safety installed & the action out of the stock, I got a consistant trigger break @ 2 1/2#.

Time to assemble the whole thing & give it a try. I adjusted the over-travel screw for zero overtravel & used "wicking" grade Loc-tite on the threads.

As I have experienced in the past W/other rifles, when the entire trigger, safety is assembled & the action tightened down into the stock, the trigger break weight went up slightly.

After spraying some G-56 lube down into the sear engagement area I now have a consistant, reliable beak @ 2 3/4# W/zero perceived over-travel. Dropping the rifle on the butt when cocked W/the safety off did not result in the striker falling. I did this several times from as high as 1'. I also slammed the bolt shut, pulled the trigger W/the safety on & them switched it off. I did these tests several times & never once did the striker fall W/O an intensional trigger pull W/the safety off.

I'm quite pleased W/a 2 3/4# trigger break. All of my hunting rifles have 2 1/2# to 3# triggers so I will be able to work W/that.

It is a far cry from the 5 1/2# pull I started with this morning.

I'm very pleased W/may 1st DIY CF rifle trigger job.

#2696 Prairiedogging with the 5mm this week.

Posted by AMMOe on 05 August 2012 - 07:27 PM

Hey Guys,

I just finished off a sweltering week of PD shooting that involved the T/C 5mm when applicable. It was fantastic. Three misses and 11 dogs total. (No pictures, unfortunately) The last dog of the day was in 102 degree heat at 156 yards using the Varmint load. He was half obscured by the waving grass and I shot him standing with the rifle foreend resting on a camera tripod. At the shot I could see the spray of blood and saw him flip backwards into the hole. My hunting partners saw it as well and were mightily impressed. I got three today: 40 yard head shot, a 100 yard shoulder shot, and the aforementioned 156 yarder. Oddly, the guys I was shooting with were using very accurate 22WMR and 17HMR rifles. They each hit an equal number of dogs but the 22WMR 40 grain killed them better. Neither of them held a candle to the Five, though. ~AMMOe

#2481 New 5MM Magazine successful test fire today

Posted by 5MMEagle on 07 June 2012 - 05:16 PM

I just finished a small but very important testfire of our new all metal 591 magazines. I was able to load the magazine into 3 different rifles and shot several rounds from one of those rifles. It is the only factory standard M591 rifle we have, so all testing is being done with it. We have a few very minor changes to make, then a quick test of those changes. We will run a batch of them. I am very excited.

Here are some photos

This magazine is not finished

#3029 A couple questions about my 591M...

Posted by Issa Akhbar on 07 January 2013 - 12:59 PM

There's no problem loading either the 591 or 592 as a single-shot; I do it all the time while sighting-in at the range. These are not "controlled feed" designs, like a Mauser claw extractor. There is a specific post on the website here somewhere for the current status of new-manufacture 591 mags...if I remember correctly, they're getting very close to being ready for sale. You should use search...
