I have the 22 Cal conversion and, for some reason I cannot sight this thing in at over 20 feet? Any ideas? I've used federal, CCI and others but no luck?
Since I'm 67 and a little shaky, I piled stuff on it to make it stable when firing, but no luck. Wondering what the deal is?

I don't know for sure, but I suspect the bullet is being spun too fast. A Ruger 10/22 barrel has a 1 in 16" twist. My AR15 has a 1 in 7" twist. That's over double the twist rate.

I considered a .22 conversion, but could not find a definitive answer about the effect of so grossly over spinning the bullet. Instead, I bought a 10/22 Takedown. I like it so much I also bought the 50th anniversary 10/22.

The twist rate was one of the main causes I saw people list for inaccuracy. 36gr Copper was recommended.

Seems a lot of people have taken this route too : get conversion kit, get tired of fouling of upper and accuracy issues, decide to get dedicated upper for it. Soon after, decide to get dedicated lower, thus building a dedicated 22lr ar-15 .

I tried to learn from these folks and just cut out the conversion kit altogether. Instead I opted for a dedicated upper for my SBR'd lower. The Nordic Components upper I ended up purchasing has been awesome. I took advantage of their Black Friday sale to pick one up. If you keep your eye on them they seem to go on sale occasionally for ~$100 off list price. Very pleased with the quality and robustness of the upper, especially for the price as compared to say the CMMG or Tactical Solutions uppers (both of which are very nice, though I've only been told that of the Tactical Solutions uppers as I've never played with one, yet).

No matter what the choice, as others have already noted, the dedicated upper route is the way to go.

I have a Spikes .22 upper.

It is decently accurate, decently reliable, but no sniper rifle. It is short barrel with the flash hider making it legal. One fellow I have read posts from elsewhere claims he can put 10 rounds in a single hole at 25 yards with a similar rifle, S&W
I think. I've never seen him do it, maybe he can.

I've never seen or heard of anyone using AR-22s of whatever configuration for benchrest matches. If they were as accurate as this fellow claims, they would be so used.

Honestly, I have never been able to understand the attraction of a .22 AR.

To each his own I reckon...

In California, where I then lived, it was a felony to have a lower and a centerfire upper without a bullet button, even if not hooked together. I had a M-4gery with a bullet button (since removed), so I got this rimfire upper. It's fun and used to be cheap to shoot when you could amble into a Walmart and buy a bulk pack for $7-8.

I don't think there is a serious use for it particularly. Nothing a 1022 or similar wouldn't handle as well cheaper.

Pure plinking fun, no other reason needed.

My first experiance with my 22 conversion kit was on a 50 yard range. I couldn't hit the side of a barn. Couln't even tell in which direction I was missing the target. Then I tried it at my indoor range at 20 yards. It still wasn't nearly as accurate as with .223 but at least I hit close to where I was aiming. So at that range it at least is still useful for training. Won't go 50 yards again.

When .22lr was $.03 per round and plentiful, and 5.56mm was $.40 per round... There was a great reason to be interested in a .22lr AR. If you had a .22lr dedicated upper built to match your 5.56mm upper, you could put it on your lower and get the same weight and trigger pull. Perfect for practice.

So now that .22LR is becoming more available, at ~.10 a round, what is 5.56 going for?

It's still more than 5 times less expensive to shoot 22 LR. And shooting AR style with a 50 round drum is a blast.

The 1,000 rounds I bought two weeks ago cost me 5 cents a round. The cheapest 5.56 I saw at Academy yesterday was 100 rounds for $40...so 40 cents a round.

I had a CMMG conversion bolt at one time. It worked flawlessly and was accurate enough for plinking.

I sold it for three reasons:
- It made my AR REALLY dirty, gunk down the in lower as well. 22lr is dirty stuff.
- I had to sight it in for either 22lr or .223. 22lr shot low to the left at 25-50 yards.
- It blew gases and little bits of debris back in my face. With every dirty shot, gasses with little pieces of 22lr debris would blow back in my face and feel like a bunch of little needles on my cheek. It didn't hurt, just annoying.

I've also read of stories where the gas tube was completely blocked with gunk from shooting 22lr.
