    hello folks!

    i want to buy a 22lr conversion kit for my AR, but i'm not sure what kind of accuracy i can expect within 100 yards from the kit. so if any of you got some pics of your targets at 25, 50, 100 yards it would be very helpful, i'm not looking for match accuracy, but i want to know what a 16'' 1/7 twist can do with a .22 conversion.

    BTW i'm looking at the Spike's Tactical 22lr Conversion.

    These kits are not designed for match grade accuracy. They are for plinking. If you need a precision 22 rifle, buy one.

    I've tried the conversion kit on a 1/7 twist and it did okay. The bullet diameter for a .22 lr is .223, the 5.56mm has a bullet diameter of .224. That is going to affect accuracy a little bit but not significantly. The 1/7 twist spins the bullet faster so you probably won't notice much difference out to 100 yards. The spike's tactical kits are the best you can get. They have gas rings on the chamber filler (ie. Dummy .223 round), come in stainless steel, and you get a set of replacement parts for your kit. Black dog magazines work well in my AR.

    Perhaps the Aguila SS 22LR round with the heavy 60gr bullet would give better results out of the 1in7 twist barrel. They do not usually work well in standard LR barrel's due to the twist.
    Food for thought.

    You'll get the best accuracy from the heavy Aquila, as NCSmitty suggests - but at 100 yds, prepare for some serious hold-over.

    My ciener kit and a 1in9 shoots around 2 inches or so at about 50 yards with ammo it likes. At 100 yards I would think it would look more like a pattern and not a group. Mark

    I wish people would quit repeating this without taking 2 seconds to verify the truth instead.

    Maybe some .22 LR bullets are actually .223 (which is the specification), but every one I've ever measured with calipers has been .225 and up. Some crappy Remington bulk pack bullets have been as large as .228! And that specific set of calipers has given me .357 for .357 bullets, .400 for .40, .308 for .308, etc. So it's not off by .002.

    i have a 1/9 16" ar(RRA) with a standard ciener kit. I shoot 2-3" 10 round groups at 60 yards with wolf .223 and I shoot 3-5" with remington subsonics or cci standard velocity. That is the only .22 ammo i have large stock of as its what my 10/22 and model 41 respectivly like, and i have a can so subs are the way to do it. The beauty of it is that my 60 yard .223 zero. I can crank my rear to 4 for a 60 yard 0 and 5 gives me a 75 yard zero with the .22.

    I have tried tons of .22 ammo but never for accuracy just for function. I tried agulia sss, i coudln't get it to cycle reliably, though pretty much everything else cylces fine with a can on. Every 40-50 rounds the hammer doesn't reset with perfered ammo. the sss seemed to have issues, best case, every 2 or 3 rounds.

    I like my dedicated upper. Those CAN have match-grade accuracy if you want it.:)

    Actually most 22 lr bullets I measure with a digital caliper are around .218...Explain that.

    I use mine for extra trigger time with my ARs. 2 of them have Aimpoints (which I don't adjust from 5.56 zero) and I'm only shooting at up to 75m (usually <50m) so it has plenty of accuracy for the steel and clays. When I want groups I use a CZ453. I never notice a difference when used in the 1:7 compared to the 1:9.

    I can reccomend the CMMG stainless conversion.

    I dont think the spikes is stainless, I am pretty sure it is nickle plated.

    I am however too lazy to go look.

    I got my CMMG stainless conversion kit for $169 with 3 mags and free shipping.

    Best buy ever.
