    CMMG .22lr Conversion

    At first I was reluctant to order something like this because I could not imagine a kit that would make a rifle go from a 556 to a .22lr. I am glad I did, it worked flawless. Shot 500 rounds with no trouble. Great addition to my AR. Now, will someone make a conversion kit that will shoot .177?

    We are glad to hear you are pleased with your order.
    CMMG .22lr Echo Conversion

    Got this product last week. Put a few hundred .22lt rounds down range, with different brands of ammo, with NO malfunctions. Taking it out again tomorrow for another round.

    The company was easy to work with. Ordered it on a Friday night, sent the company an email on Saturday, and they responded back to me on Sunday, with a tracking number. I only have good things to say about this company. I will order from them again.

    Quality product. Very happy with service, shipping and all around experience.

    CMMG AR-15 .22LR Conversion Kit w/ Phosphate finish + One 25 Round Magazine - 22BA6FD

    An excellent little unit. Very satisfied with it's performance in my Colt AR-15 A2 Gov't Service. Fired a few Aguila 60 grn rounds through it too, but they did not all have the moxy to cycle the bolt. Didn't want to run too many through the bore as they are not the recommended copper lubed bullet (although accuracy was very good). This unit DID chew up the hammer in my NEW FRONTIER polymer lower, however; yes, they do sell a narrow one that functions perfectly in this conversion.

    Went out and shot my AR with my new .22 Conversion Kit. Worked flawlessly!! Had a great time shooting without spending a ton of money. I highly recommend this product.
