Receiver mortise/Barrel tenon measurements

I'm tired of loose barrel vs tight barrel scenarios, what where the numbers intended to be so I can adjust accordingly. I've always sacrificed the barrel tenon, but on this build I thought the receiver is 1/2 the cost of the barrel ????

There are a few ways to install the barrel in a receiver, most of which are available her at RFC using the search. A good suggestion is to ask the barrel maker the proper method to install to the receiver. I have done everything from slight sanding to freezing, never seize products, etc. I would be hard pressed to recommend what's best. Perhaps Kidd may have the best suggestion. If you are asking about in/lbs torque, I have found that equal or 2 in/lbs less than action screw seems to work well. ....... AH

Yep thanks for the video. That’s how I do it , minus the gauge and the cookies . I’ve never had to heat the receiver. , and part way in i slip in the vblock, and I clock it to the bolt I’m gonna use so the extractor is in the middle of the cut.

Well after some sanding the barrel measures .6877", I don't have a bore gauge that small so the receiver I can only measure with a caliper. Alignment is not even a concern since it gets pre-aligned prior to even touching the receiver.

The v-block is pre-installed so the barrel just slides into the receiver studs. The build I did last month I froze the barrel and heated the receiver and I still had to run to my press to get it in before it got stuck(same barrel/same receiver). I'm currently setting up to sand the receiver now.

Uh...........? I don't believe I would sand the receiver. Been there, done that. Barrels come, and barrels go. You may suffer from "sanding remorse". :oops::protest_e:1t:hide::boohoo::hide:
Why ask for good advise and then ignore that good advise?
Who asked for advice?This is like my 30th build, I asked for hard numbers, in any case this is now done and it did go better. I'm thinking I might invest in a reamer for the future receiver bores. I will post pics tomorrow in my BD thread of the progress.

I should add that after sanding and measuring the barrel tenon, it would indicate that the receiver bore is to tight. Probably the anodizing because with the light controlled sanding it was a great fit!

I don't blame you at all for not asking for advice here. More than half of it will be bad advice based on repeating Internet BS at best!! You can buy all of the reamers you want but in the end the 10/22 is a crude machine. Sanding a barrel or receiver is at best a shade tree approach. I laugh at many of the post here.

When mr Kidd said that the baked receiver might cool off and leave an oval hole, I heard the word warped and wondered what else might not come back in the same shape as it went into the oven.so I’m never gonna put a receiver in an oven. Might try freezing the barrel . I’ve only pounded on 3 barrels into stock receivers. Greased them all an all have been tight . All have worked great. A ksa and 2 gms. I have two more gms to do. On as a replacement on a DSP,and one abuild , Running Boar.. just accumulating some more bits and pieces first.

I always get a little anxious but then everything seems to go right and I’m done.

I think sanding the receiver hole was a wise choice. Much less chance for error , and if it’s to big for the next barrel , some metal tape could probably fix the issue.at worst a helicoil and a threaded barrel.but the barrel if sanded incorrectly might not be salvageable.

One thing for certain I will not be buying fancy receivers with too tight holes. The $70 Ruger receivers seem to work well enough for me.
