GStephen Posted February 26, 2023 Report Share Posted February 26, 2023 What’s required parts to change a LR308 to a 22-250? What parts other than the barrel? Quote Link to comment Share on other sites More sharing options...
GStephen Posted February 27, 2023 Author Report Share Posted February 27, 2023 I know that I would also need a new gas tube. But wonder about bcg. Lower has 5.2 buffer and orange spring already. Or is it an all around stupid idea? Quote Link to comment Share on other sites More sharing options...

shooterrex Posted February 27, 2023 Report Share Posted February 27, 2023 From what I can find the 22-250 and 308 case head is the same. So changing out the barrel is about it. You might need a different magazine. Quote Link to comment Share on other sites More sharing options...
BrianK Posted February 27, 2023 Report Share Posted February 27, 2023 Just MHO, but that would make for a really interesting rifle. But one question, why not make a new upper and have both? Just curious, no judgement. Quote Link to comment Share on other sites More sharing options...

But after looking at prices the bear creek uppers look about as cheap of a way to get one as buying pieces and using my working 308 upper. Now, to decide which barrel type and length is the question. I have ammo for my model 70 bolt 22-250 is part of the reason I am thinking of that caliber. Since I retired my gun money is much less than before.

Looking at the money as the first priority usually involves work - and more money, in the long run - to fix it, and make it run right. That fancy low sticker price that you see is never the bottom line. Never is. Take PSA PA-10s (all variations) for example. JMHO. Quote Link to comment Share on other sites More sharing options...

Since I already have a working aero m5 lower with 5.2 buffer and orange spring I thought that a drill bit and possibly the right gas tube would have a good chance to make it cycle. I read the posts about the bca 22-250s and it seemed that was the cure. Quote Link to comment Share on other sites More sharing options...

StarWolf Posted March 1, 2023 Report Share Posted March 1, 2023 I am tempted by the .22-250 but as I don't have ammo in the caliber that temptation is somewhat lowered. I'm also tempted by the 7-08. On that one I've got ammo. Barrels seem to be a bit more expensive. Ammo is starting to show up in some of the not quite as common calibers but .308 is still the most common major rifle caliber on the shelves.

GStephen Posted March 2, 2023 Author Report Share Posted March 2, 2023 (edited) I ordered the 22-250 last night and tracking shows Saturday. I was coyote hunting last night and missed one at 250 yds with my 223 with thermal scope standing up off my tripod. I adjusted the scope a bit today and shot 3” group at 200 Edited March 2, 2023 by GStephen Quote Link to comment Share on other sites More sharing options...

The gas port is .088” and the gas tube is too short as expected. It’s a 20” rifle length barrel and rear charging receiver. I haven’t shot it yet until I get gas tube fixed. I have an extra adjustable gas block if needed later. .750” gas block on it now Edited March 3, 2023 by GStephen Quote Link to comment Share on other sites More sharing options...
GStephen Posted March 3, 2023 Author Report Share Posted March 3, 2023 I decided to go ahead and shoot it. It worked perfectly. First shot it locked open. Then it cycles great after I put more in it. I will probably go ahead and get a gas tube. Happy with accuracy too. BCA doesn’t suck too bad today. It threw the brass about 2 o’clock Quote Link to comment Share on other sites More sharing options...

If you can find that one, see of whatever I came up with is similar to what you have on there now. Quote Link to comment Share on other sites More sharing options...

GStephen Posted March 9, 2023 Author Report Share Posted March 9, 2023 I modified the follower in a Pmag 10 round magazine to let it tilt under the cartridges. To help keep more tension on the fronts since they are tapered so much. Cycling by hand it works great. I will shoot it when it quits raining. I also got the suppressor mounted and need to check poi I was only able to put 5 rounds in before because there was no support for the front of the cartridges.
