The bolt is removed from a Marlin model 81 by first opening the bolt completely, then while holding the trigger back all the way, continue to pull the bolt the rest of the way back. Sometimes it is necessary to hold the trigger back while re-inserting the bolt.
Try holding the trigger back when you remove the bolt
If you are referring to the model 58 22 cal. bolt action rifle, push the thumb safety all the way forward toward the muzzle, open the bolt, pull back and the bolt will slide right out.
Make sure the rifle is unloaded. Then close the bolt. Then open the bolt, but do not pull it back. Now, pull and "hold" the trigger pulled back, and then slide the bolt back and it should slide right out of the receiver. To put the bolt back in, do the reverse (hold the trigger back and slide the bolt back into the receiver, then release the trigger).
Open the bolt, pull it to the rear, hold the trigger back and remove the bolt. sales@countrygunsmith.net
If you look at the very back of the receiver on the left side there will be a small tip of the bolt stop showing in the left bolt guide channel, push it down while the bolt is open and pull back on the bolt. Should fall out .
Bolt removal on this model is fairly straightforward and simple. First work the bolt to the rear as if to chamber a shell. Second pull trigger and continue to pull the bolt to the rear and it will slide out the back of the reciever. To reinstall bolt complete this sequence in reverse.
Raise the bolt to the unlocked position, then pull the trigger while removing the bolt. That makes no sense. The Model 60 is a semiautomatic firearm, not a bolt-action. The old style Model 60 used the operating handle as a bolt hold-open. Pull the bolt about 3/4 way to the rear and push in on the bolt handle to lock it open. Pull the bolt handle back out and the bolt will be released to run forward. Newer Model 60's have a bolt release lever that extends down through the trigger guard.
Open bolt and pull to rearword position.Then pull trigger and hold in back position.Bolt will now slide out.Hold trigger back to reinstall
the safety switch, just behind the breach, next to the bolt, doubles as the bolt-release. with the gun unloaded, pull the bolt back and push the safety switch forward past the "fire" position. the bolt should then be released so that you can easily pull it out of the back of the gun.
Usually the difference between series like this is listed "minor improvements" but this time I actually found something in the Blue Book of Gun Values. "The Model 69 was cocked by the closing motion of the bolt and had a non-swept back bolt handle, whereas the 69A was cocked by the opening motion of the bolt and had a swept back bolt handle."
Hold down the safety switch and gently pull the bolt out, and a 1/4 turn on bolt at point where it sticks. On the Savage 340's. With clip out and safety off pull back the bolt as if you are chambering a round till bolt is all the way back. Pull trigger back fully and slide bolt out while trigger still depressed. To reinstall hold trigger back fully and slide bolt back in same position it was removed.
