I was reading K2unit's thread on the ar10-06 and i started typing a response. the response got so big i decided to start a whole new thread.
I like the idea of a scaled up AR action for the 30.06 with one little change.....
300 win mag out of BAR mags. I mean dont get me wrong the 30.06 is great for cheap blasting but the standard should be set at the 300 win mag. Because if the want for scaling upwards to a larger bore size should ever strike your fancy then why not have magnum rated parts ready to accept that mission?
I know its not much different than whats been talked about already but its been messing with my
head the past few days and I needed some further advice thats why im starting a whole new thread.
Gas system. I dont really think its a matter of scaling up the action.... well to some extent yes but most of
the extraction, cycling, and recoil issues can be massaged and tuned with an adjustable gas block.
The only one I've assembled and worked with is Armalites SASS gasblock, which only has 2 settings, 3 if you count the "off" position between the 2 exhisting marks. the knob at the front of the block is one piece with a cylinder extending into the gasblock. The cylinder has 2 ports drilled on its side, one hole bigger than the other. the opposite end of the cylinder leads to the gastube, which is flared and has been
affixed to the cylinder with a nut.
Now by my thinking it wouldnt be too hard a job of modifying the cylinder to have more settings. Or to start with a new custom cylinder to make whatever sized ports would be necessary. drilling the gas port on the barrel to max size and working it down with cylinder settings seems like a good way to test feed and function.
bolt and barrel extention. Wether you agree with it or not a semi auto will never be as accurate as a bolt action. But I really believe this to be all related to the design of the bolt and the barrel extention itself. There are designs out there already that can mate with current AR10 carriers that can be improved upon.
Parts and pieces? well thats simple. this should run off of an ar10 parts kit. standard parts for an extraordinary build. standard buffer extention, standard handguards, i mean why scale upwards in everything? If we know where the problems lie then the max amount of standard parts can be used and the whole project can keep the regular modular nature of your everyday ar15/ar10. Your choice of stocks and handguards,all on a custom receiver that shoots a magnum sized cartridge.
i wish i had some pics to post so you guys could visualize this but maybe later. I gotta go pick up my kid from school.
