Many years ago I bought a knock-off of the famous Browning .22 Auto which comes apart in two pieces (an early 'take-down'). I still have it; it's made by Norinco and sports a cheap scope to maintain the 'cheapo' ambiance of the rifle. I found that there is a simple adjustment ring that increases or decreases the barrel fit to the moving bolt. Forgive my lack of proper terminology. But I can tell you that nice tight-fit setting makes this cheapo a real tack driver. It's so diminutive, you could hide it in your shorts :-)))) Pd. a whopping $99 for it (maybe 20-25 yrs ago). Hoping to get a 10/22 after COVID.
