Don't pull the trigger and drop the hammer, just all the way back and all the way forward, using the action release. One thing to consider about action smoothing is that a judicious application of talent will undoubtedly create a smooth condition without any wear condition being counted upon to mate the parts together. Best thing I can recommend is to disassemble it and wipe all the excess oil and grease off of everything, then put it together and sit and watch TV and work the action.(Want to embarress a few upidy shooters pretty soon with that gun). They can have more in sighting/laser/flashlight/handgrip/rails/speedfeed etc. Let's say a shooter has a crooked choke tube hole that makes the point of impact off 8" at 20 yards, but a new straight choke hole is less than 2" off at the same distance?
Article 3 pictures improper or dangerous choke installations, article 1 has explanatory illustrations, and article 2 has info. The only thing inside the receiver of your 870 touching anything else when you rack it is the the action bars are running in channels in the walls of the reciever.You will not rack it harded then that gas piston and you will not send it home harder then that action spring. Mc Guire Custom Built Home Defense, LEO Duty, & Tactical R870's Remington Factory Certified LE Armorer Refinishing, Rebuilding, Upgrades, Accessories 231-690-0954 / [email protected]'s quite a pronouncement there, saying that nothing on an 870 needs smoothing.I am telling you this so you understand that you can not hurt the 870 and it was made to rack hard.guys that told you to go shoot it in are correct.I know others will jump on my comments and disagree but unless they are Factory Certifed Remington Law Enforcements Armorers like me then they are giving you opinions, I gave you facts and if they are Certified as I am and they disagree they are not disagreeing with me but the Instuctors who Certified them as I have simply repeated what I was taught at the factory about this weapon. (That doesn't mean that I think you don't have some good points listed, otherwise)I'm not trying to start an argument, but since my "opinions" have been slighted, I must respond with some clarified points to allow readers to better form their own "opinions".---------------------------------------Stating that the only parts touching anything else when you rack the gun being the action bars would be correct if there were no parts inside the frame except the action bars.In my neck of the woods break in robbery is getting more frequent and this short barrel 870 is the trick for defense since it is what I have used since a young boy. Attainment of infinite perfection- sorry, not here. POI can vary due to shells, anyway, just like a rifle may only be zeroed with one specific load to be the closest to "dead-on" target.Just trying to "fix it up" and learn a little in the process. As I mentioned, most guns are functional, and only a few examples (of certain otherwise mechanically sound design) will have function compromised by fit or meshing incompatibilities that, once improved, make the reliability the equal of anything that a person would use in defense of self and family.smooth parts rub, and help them realize that some parts that are hard and moving against softer parts will not go dull for a very long time, if at all.
