.22 Conversion in AR15

pphil09 · 04-10-2011, 12:41 AM

Does a .22 conversion cause any long term damage as far as accuracy and durability/reliability of the rifle when switching back to .223? The ammo I would be using is 36gr .22 Federal Champion HP's with a copper plating.

No for two reasons.

1: you are basically changing the whole upper
2: you are basically changing the whole upper

How about the bolt conversion kits?

GlockMan · 04-10-2011, 10:44 AM

I never could understand doing this.

Is a good quality conversion not close to a regular .22 AR style rifle? (within a few hundred)

kaput · 04-10-2011, 12:24 PM

They are, but some want one gun, multiple calibers to use their trigger and other support pieces.

I agree, converting the upper is quick, but pulling out a different rifle is quicker.

I know CMMG sells some .22 bolts that some have reported good results with. You shouldn't be damaging your rifle by swapping between .22lr and 223.

Reedo302 · 04-10-2011, 03:25 PM

I don't foresee any damage issues.

pphil09 · 04-11-2011, 04:42 AM

Ok thanks reedo. For those asking, the CMMG kit is only 134 shipped, which is much cheaper than a MP 15-22 or a dedicated upper. I would also like to use my optics and practice with my main gun, not a plinker.

link to the CMMG deal?

Apparently they are out of stock now? It says "call" but I was able to order online. Never heard of the company but they shipped it quickly and im pleased overall.

Let me know how it shoots, I have a 1:7 twist on my DD and Ive heard that it can really mess with a .22.

Ive also heard that you need to shoot some .223 after a day of .22 b/c the .22 is dirty and might start to clog up the gas block and tube...

pphil09 · 04-12-2011, 11:49 AM

Yeah my BCM is 1 in 7 also. Will report back results.

kevmo · 04-19-2011, 05:02 PM

kevmo · 04-19-2011, 06:19 PM

conversion i meant*

pphil09 · 04-24-2011, 02:07 AM

Results are G2G. Leaves a lot of burnt powder residue in the upper part of the upper, but nothing that a toothbrush and rag cant get out. Accuracy isnt exactly pinpoint, but I'd say I didnt see anything outside of more than 12 MOA at the absolute worst. Most were probably within 6 MOA of where I was aiming. I have been using 525 pack Federal Champions and running a bore snake every 100-200 rounds.

Initially I was getting some 3 round bursts and fail to loads out of the kit, but it definitely does have a break in time, and over the past 400 rounds I have had 1 stovepipe that was easily cleared. Everything else has been 100% even at rapid fire speeds. Fun little kit, definitely worth the $134 from the company I linked to.

I have one and its worth it, I just switch back to a 223 bolt at the end and let go a couple to just make sure the gas tube is clean(ish). If your really worried just buy a new upper and dedicate it to .22 only.
