Removing and disassembling the bolt of a Swedish Mauser is a pretty simple affair and may need to be undertaken for any number of reasons. Most commonly, you’ve picked up a rifle nearing a century in age, and there’s a lot of gunk and crap in there that needs to be cleaned out. The other scenario is that you could be modifying your bolt to cock on close, or reduce lock time with lighter materials and a stronger spring.
Hopefully if the latter is your reason for stripping a Mauser bolt, you’ve inherited or bought a sporter – there are fewer and fewer whole specimens left.
Below are a series of pictures showing how to disassemble a Mauser bolt (small ring, not a K98). If your bolt looks different, don’t fret. This is from a commercial rifle, not a military conversion. It has a blued finish and a bent bolt handle, which thankfully clears my Weaver 44/40 scope, thanks to an EGW 20 MOA rail. If you’re wondering how the extra height affects consistent cheek weld and sight lines, a Boyds stock with adjustable cheek rest helps out there.
Step 1 – Get the firing pin out of the bolt body
After checking the rifle is unloaded, close the bolt fully.Lift the safety lever into the upright position and remove the bolt without lowering the safety. You may need to remove your scope if the safety won’t clear it.The bolt shroud should easily unscrew from the bolt body now. Note the cocking piece is held under spring tension by the safety lever.The firing pin separated from the bolt body. Again, note the spring and firing pin are locked back – if you don’t do the next step carefully, the spring, cocking piece, and firing pin could separate with a fair amount of speed and force.
Step 2 – Separate the firing pin from the bolt shroud
Find a hard surface you don’t mind denting. Or, if you have an original stock with brass disc, you can use the indent for this step. With the firing pin against your hard surface, force the bolt shroud downward. The safety lever provides a good amount of purchase.Twist the cocking piece 90 degrees. At this point make sure you have a firm grip on the bolt shroud and firing pin, and slowly release the spring tension to avoid sending pieces flying.Fold the safety lever all the way over and pull it back to separate it from the shroud.Shroud, cocking piece, spring, safety lever, and firing pin.
Step 3 – Remove the extractor from the bolt body
Note the extractor sits in a groove just before the bolt face.Rotate the extractor about 90 degrees so that it exits the notch.Apply downward pressure with your thumb, as you slide the extractor forward. Remember this sweet spot, as you’ll need to apply pressure in the same spot to get the extractor back on.Getting this collar off is easy, but you will stretch it as you do so. A flat screwdriver can be used to pry it open if needed. Getting it back on once it has been taken off is harder, and a vice of some sort will be handy, as you’ll need both hands to get the extractor back on.When reassembling the bolt, getting the extractor onto the collar is probably the hardest bit. If you have locking pliers or a small vice, it shouldn’t be hard to slide the slot on the underside of the extractor onto the collar. Remember where you applied downward pressure to remove the extractor – this is the same spot you need to apply pressure to as you slide it back on.
From here on, the rest of the reassembly is easy, and is simply the reverse of the above.
Whenever there is more than one option, shooters around the world will have vastly differing opinions for and against each. The same could be said for push vs controlled feed bolt action rifles. However, after over a hundred years of having both on the scene, it seems a sort of stalemate has been reached.
So, what’s the big deal?
People still have their preferences, but realistically, there are much more important factors to consider when choosing a bolt action rifle, and the feed/eject mechanism is almost ancillary to other concerns. That being said, there are differences.
The double feed
A push feed action is exactly what it sounds like. The round is pushed by the base of the bolt into the chamber. Once the bolt is fully closed the extractor claw will engage the rim of the cartridge, so that the ejector plunger can push it out when it’s clear of the chamber again (once the bolt is pulled rearwards).
The oft-quoted push action double feed can occur if you do not fully close the bolt upon chambering a round. This means the round will not eject as the extractor claw has not engaged the cartridge. If you move the bolt forward again, you’ll feed a second round into the base of the first.
The bolt in this .243 Stevens literally pushes the round without grabbing onto the rim until the action is fully closed.
This situation is very unlikely to occur, except through clear operator error. We all like to think we’re beyond such simple mistakes, but stress can cause us to do funny things. When might you be this stressed? Hunting dangerous game, or perhaps in fast-paced action matches like the Precision Rifle Series. However, most competitors use modern push feed actions without any issues. Big game hunters on the other hand, are probably the biggest proponents of the Mauser-style controlled-round feed.
Making life easier
The main reason for the proliferation of push feed rifles is that they are cheaper and easier to manufacture. Having said that, some very expensive, reliable and accurate rifles use push feed actions.
There’s one thing that just makes like easier with a controlled-round feed. You don’t have to push the bolt fully closed, or completely work the action, to pick up and eject a round. And no, this isn’t the same point above worded in a different way.
This Mauser action with its large claw extractor grips the round upon picking it up out of the magazine.
If you spend a lot of time on the range drilling small holes into paper, you’ll come across plenty of situations where you have to clear your rifle so someone can go forward. This may be for a change of targets, a ceasefire in a match or some other situation where rifles need to be made safe.
If you have a box magazine, no issues either way. However, if you have a blind magazine, emptying a full mag with a push feed action can be annoying and time consuming. A good example of this is the Mossberg 100 ATR which I recently reviewed. A nice, slick bolt action, but you can’t pull the magazine out or drop a floorplate if you want to quickly empty your rifle.
With the Mauser-style actions built by CZ, Winchester (some model 70s), Ruger, Kimber and others, you can simply move the bolt a fraction of the way forward and pull it back again to solidly pick up and eject a round. I do also find that the bolts are generally less sloppy in the action, as the long extractor acts as another guide to keep the bolt going forward and not sideways.
These sound like silly points to favour one rifle over another, and they are. Although it’s a feature I really like, it wouldn’t influence which rifle I bought if I was choosing between two (unless they were otherwise identical, which isn’t going to happen).
