    CMMG Unit Damaged Upper Receiver

    Austin, I have already contacted Tech@CMMG and described damage in detail (with photo); he described slice as normal.
    At the recommendation of Palmetto Armory, I contacted Logan at
    CMMG. I described situation in detail. I volunteered to return upper receiver and unit to them for inspection; I also said I would pay
    cost of shipping if what I described were not true.
    Logan indicated his committment to customer service; he said he would speak to owners, but I have not heard from him.

    I am seeking more info on CMMG conversion units and alerting others to problem I am having which is clearly within pervue of site.

    I think your comment was really inappropriate and presumptive for a "senior member." If there is one thing I do not need, it is your sympathy; however, now, others are aware of your ministry.

    The only two things I could think of that might cause this are:
    The conversion was put in at an angle, or the rail chamber adapter was not snapped onto the rail on one side.
    A slight amount of anodizing might wear off from metal on metal but there is no reason for the kit to make a cut on the inside of the upper, especially if it slid in with no issues.

    You're wrong. Austin's comment was entirely appropriate.

    You should have explained in your first post that you had already contacted CMMG and that they blew off whatever "damage" their kit did to your receiver.
    There are too many knuckleheads on forums like this who first complain to the www, and only later (or never) contact the manufacturer/retailer in question. You should have made it clear from the start that you're NOT one of those.

    As for the "damage," I'd still like to see some photos. As to the cause, see shadow's post here, or mine, above.

    CMMG Unit Damaged Upper Receiver

    He began with a presumption that was insulting. You are doing something similar; you are using knucklehead to someone you have never met. I hope that you are not involved in PR, the ministry like Austin, or neuro surgery. Are you a knucklehead? You sound combative and reactive.

    I left my camera when I visited my newborn son last week.
    However, I sent Jordan at CMMG a photo of the damage, and I will ask him to post it. Interested and intelligent people will
    be able to see the damage, and CMMG will be able to show
    what NORMAL WEAR from their unit looks like.

    You still have not answered if you had trouble installing the kit or any problems cycling.
    Something very out of the ordinary happened here.
    1000's of these have been sold and no telling how many Atchison style bolts over the years but you have one that caused damage to your upper receiver.
    Wearing some anodizing off, I could understand. Other than that, there is nothing to "cut" your receiver. Maybe you did it when you pryed it out.
    You have went to several forums trying to state that CMMG's conversion kit damaged your upper but there seem to be parts left out.

    I read your post. In no way did you indicate that you had contacted any CS entity, nor is Austin or anybody here capable of reading you mind. You PRESUMED that it was understood, when it was clearly not, but instead of simply saying that you had contacted CS, you decided to start flailing about wildly and namecalling.

    That finger you're pointing at the folks you're calling 'knucklehead'...?

    ...bear in mind that there's three other fingers on that hand that are pointing back at you. Knucklehead.

    Your next post in this thread will be one that hosts the pictures of the damage. Period.

    Just recieved my CMMG conversion kit today! No time to shoot it,but I'll get out tomorrow and try it in my 16" carbine first as it has 1:9 and a rounded hammer already! I'll try the Colt as well in 1:7 but it has a notched hammer! I'll let you know how it goes with targets!

    PS mine is the parkerized version!

    The parkerized may take a little more breakin. One of the best things you can do to that kit is buzz the chamber.
    Chuck a brass .22 bore brush in a drill, put some oil on it and run it in and out of the chamber until it's warm. This will polish the chamber and help insure feeding.
    My kits have worked with notched and un notched hammers. You just have to try it.
    If you have any questions or issues, let me know.

    Went out and did a quick shoot with the 16" Carbine 1:9"! Used Fed 36 gr High Vel and Standard Win 40 gr target loads ! Other then a couple weak rounds in the Feds ( barely ejected) everything fed perfectly!
    Shot two targets at 27 yards (lasered)! I did not adjust my optic for these so thats why the 40 gr are low on the target used the KW to get the 36 gr to print higher! I hope to get out with the Colt 20" 1:7" tomorrow as this is the one I'll use most with the Convert !
