I am thinking of putting together a regular AR and installing a 22 conversion kit for my sons birthday later this summer. But I see S&W sell a MP-15 22lr rifle for not much more that the price of the 22 conversion kit.

While I understand that a rifle with the conversion kit will not shoot as good as a rifle with a dedicated 22lr barrel. I just not sure which way to go with this.

What would you do if this were you?

The M&P 22 or a dedicated upper if you *ever* think you might use it for more than a slingshot that goes bang.

Less than good accuacy is frustrating as is sight not zero'd to that combo.

Blondzilla has the S&W 15-22 with a small red dot and everyone who shoots it loves it. It has fired countless hundreds of rounds without a failure as well (knock on wood).

AR but if you want to shoot 556, just swap out the bolt

I assembled a dedicated upper with a barrel from Clint Beyer. The result was a fun, accurate, reliable (with the right ammo and magazine) rimfire AR.

Tim from taccom3g has good stuff too and is exceptionally helpful and knowledgable.

I'm certain I paid much more than I would have if I went with the S&W. But... I enjoyed the exercise of putting it together. And I can later simply change the barrel if I want another .223 AR. I would not consider shooting 22lr out of an AR barrel a viable option. Inaccurate rifles are not interesting to me at all.

If you find any value in a father/son gun assembly project..... build it. If you think your boy might someday do a barrel change and turn it into a .223... Build it. Otherwise the S&W is likely a better value.

Well, after much looking around I think I have decided to go with the M&P 15/22 for this year and will save the Lower and parts for a build next year.

Ive owned and put thousands of rounds through a CMMG conversion. In those thousands of rounds I only recall a small handful of ammo related malfunctions. The concept of dropping it into your primary rifle and shooting all afternoon for $50 while keeping all the weight, balance, and muscle memory the same was a huge plus for me. Very accurate, though POI was 4" low compared to where 5.56 would land at 25-50 yards. It is something thats 'fragile' though, so you have to be careful with storage. Once installed its solid.

I personally like the idea of the M&P/22, but didn't like the rifle itself. It just felt too light for me. But as a plink toy, especially for new and casual shooters, its great.

Actually being light is a plus for my young son, as he can lift my regular AR he just can't keep it up in position for long periods of time.

I built up a dedicated CMMG upper since I already had their conversion kit. The conversion kit ran fine I just decided to build a dedicated .22 AR since I had most of the bits already. I think I had to buy their barrel and a sleeve for the conversion bolt. It runs great and is very accurate. I have friends with the M&P and they seem to like them, especially for the money.

Well I went ahead and bought the M&P for my son. I think this rifle being lighter than a regular AR will help him to shoot it and not worry about him dropping it. I hope to get him interested in shooting some matches with this rifle then progress into a regular AR. Thanks

The M&P 15/22 is incredible!
I've had mine for a month and it is so light and accurate you will be impressed.
I got it in 16" bbl. Fool proof.

I started with a conversion. Then went with a dedicated upper. My issue with the various fully dedicated 22 rifles is that the lowers won't take centerfire uppers and they aren't suppressor friendly with pinned muzzle brakes.
