I'd really like to see this 'forum' blossom, only because the Ruger 10/22 rifles are fun projects to easily modify and assemble into personal rifles having an owners wishes involved. I'm careful not to use words like "built" only because I was once told by a BATF-E compliance agent that came to my shop to do a records audit that when I was assembling 1911 pistols and by fitting slides and frames, that I purchased, and were actually "built" ( made ) by folks like Caspian Arms, Les Baer and a couple of others, that I was manufacturing and needed to acquire a "manufacturers license" which is extremely costly on a yearly basis. I know, it makes no sense considering someone else is actually MAKING the parts and we are doing some fitting and assembly. Anyway, since I don't need to have any 'black helos' and dudes wearing balaclavas swooping down on my empire...........I'm gonna be doing "personal touches" and some very slight modifying on Ruger 10/22's. One thing I've noticed when dabbling with these fine rifles happens when installing the 0.920 diameter bull barrels 18 to 20 inches in length. Some engineer at Ruger back in 1964 felt that the receiver only needs to have one action screw to hold the receiver down and into place. Well, thanks to some of the most innovative folks in this great country of ours, it was discovered that a much better quality, and heavier barrel, will get these rifles shooting groups not realised previously. It was also discovered that the heavier barrels shot best when free-floated. Now, here's where that single action screw does not always do its job very well, and 'barrel droop' can occur. The barrel doesn't actually droop, but, because of its heavier weight, it will tilt forward until it engages with the barrel channel. Not the best for accuracy. I know, some folks will bed the complete barrel into the forearm and let the receiver float. Sometimes that will work, other times, not so much. Here's what I like to do: I set up the receiver in a fixture I made to hold the receiver in my mill to add a tang onto the very back face of the receiver: The tang is then inletted into the stock and then the receiver tang is bedded in place using Devcon liquid steel: Now, I feel assured that the receiver has absolute contact with the stock and the barrel will remain floated and not eventually droop down and into the barrel channel. Is this an extreme measure? Well, it depends on where you personally want to go with your 10/22 Ruger. It's just another means that helps these rifles shoot better and more accurately. And, there are several other means that an owner can do themselves IF they choose to do so. Groups did actually improve on this version.
