M9 custom, Ruger MK II work in progress, Rem. 700 in 7.62, winchester 290, remington 870
situation; someone came to me with heavily rusted and seized MK II and wanted to know what it would cost to make it serviceable and ready for sale. i gave my honest opinion that it would be cheaper to buy a new gun than what it would cost to restore it. they checked with a few other enthusiasts and two local gunsmiths that confirmed my opinion. they came back to me and asked if i wanted it for parts or for whatever. i said yes and decided to do the restoration myself more as a training point (i screw it up and i didnt pay a dime for the firearm, but i have a lot of new tools, or i work it properly and have a new gun and new tools, so win win)after two weeks of soaking in oil and gently working parts i was able to get the magazine out. another week or so after that i was able to disassemble it as completely as i can, there is one part in the upper that im not sure how or if i can remove, and i think i need to break down the mainspring housing, but i havnt done a lot with staked pins. so ill be doing some research on removing and replacing staked pins, but my main issue is medial blasting. from my research i think ive decided on using 120 grit aluminum oxide blasting media at 90 psi to remove the scaled rust and current finish. my plan it to de-grease with simple green for a major wipe down, then heated (120 degree or so) duracoat true strip. wipe down and then use clean true strip again (yes gloved for with whole procedure and contantly swapping to clean gloves) media blast, final de-grease, then a 7 to 8 second immersion in the duracoat black dip and then into a manganeze park pank thats properly seasoned. i will have the barrel rammed with silicon plugs, but i am curious should i do anything to the feed ramp to protect it at any point (like the media blast) same thing for the bolt itself. i have it fully broken down but i see some portions are finished and some are not. i am looking for solid advice on how to proceed. tomorrow evening i will be posting pictures of the current state of the firearm. im not a shutter bug and wish i had pics of it when i got it, but the best i can do is what i have now. any input, anecdotal or otherwise is appreciated, same with comments and criticism of my plans. but i am looking especially for similar instances. any help or advice will be greatly appreciated. thank you all!
