    I will have bolts and sears ready before the end of the year. I am really hoping to have them ready by Fall Knob Creek. Other parts will be added to my website as I get them ready.

    Are you doing any redesign of the bolt? I have heard of modifications where the extractor location is changed.

    Like in the sense how mk760 and a sw76 are in different positions?

    Marcus, thatís scary, I would really like to get a sear or two, mine has a hairline crack and I am not thrilled about the lack of aftermarket parts...

If someone were producing a reliable supply of bolts and FCG parts I suspect the family would see increased popularity even though they remain relatively non versatile comparatively. Unfortunately as it stands if you break a bolt your gun will be consigned to safe queen status and you'll spend months (years?) searching for a replacement. I watched for two years and only saw one bolt come up for sale; IIRC ReconOrd sold it for $900 a few months ago at auction on GB.

    Personally I think that the need for spare parts is a bit exaggerated to a certain extent. These are robust tool steel guns with thick dimensions - the liklihood of a part breaking is low. HOWEVER, in your case where a particular FCG part has already demonstrated that it is failing, I would NOT continue to shoot it. The gun could run away in F/A if the sear fails. Plus, a competent gunsmith may be able to repair the part in it"s current state before it (and possibly the gun) experiences greater damage.

    Hopefully those with more knowledge can offer you advice. If not you should seek further input.

    Woodenword, I may do a modified bolt were the extractor is rotated towards the ejection port but to use a modified bolt like that your 76/760's trunnion will have to be cut out and re-machined or clocked so the ejector cut lines up with the new bolt and welded back in. I am not sure how many people will want to do that.

    Marcus99, The 76/760s are not made from tool steel. most of the parts are made out of 1018 mild steel. The MK760s sears and triggers are made from castings. The trigger bar in all of them are just three peices of sheet metal riveted together. The parts were made thick so the manufacturer could skip the heat treating of the parts. These guns were never designed to last as long as they have. I am by no means saying they are bad guns, they could definately use some improvements and once I get parts for them into production people will start dragging them out of their safes and not be so worried it something does break.

    Thank you for the correction Richard. I welcome the availability of durable replacement parts for those prone to breakage, especially a bolt, FCG parts and barrel nut retaining latch. I'd probably shoot my 76 more frequently were it not for a slight concern of something breaking, justified or not.

    I noticed an MK760 went for $8500 on subguns, is that the new price for these? Seems pretty high.....

    was a place advertising in firearms news awhile back that had loads of parts. They sold out very fast even at $$$ prices.

    mk760 was one of the few guns I wish i had never sold.

    I have a new in wax paper F/A Bolt for a MK Arms 760. I recently dropped it into my Smith & Wesson to test the fit. The bolt seemed to fit ok, and drop forward properly with the actuation of the trigger, but for some reason, the selector switch will not rotate fully in the Safe position. The notch cut for the sear must be slightly different. I'm not a true believer when I read that the parts are interchangeable between the two.

    Richard at BWE could answer that I’m sure. Maybe he will see your post.
