Re: Canyon rifle vs. self built
I of all people understand wanting to do stuff yourself and not to pay more then you need to for something. You have left a few items out:
ejection port flaring
HD firing pin spring
2 flush cups in stock
HD bipod mount
Last but not least I though a lot about this comment before putting it out. I do not want to come off sounding condescending etc, but I truly believe that no matter who puts your stuff together (no matter how good they are) it just won't be like one of ours. While there are a number of great builders out there (several on this site) you can pick one of our rifles out of the crowd. This is mostly a fit and finish issue, a lot of guys build really good shooting rifles and the fit and finish is good, if you look at a DE rifle and most of the others you will see the detail differences. If you don't you will be paying just as much for it from them.
I would recommend that no matter who you get it from, get it all don't at one place. Good luck with your project.
