    Cool

    Twist rate. Std. 93 barrel twist rate is 305mm or about one full turn every 12.2 inches and usually are not marked with the numbers 305.
    The number 178 means that the twist rate is one turn every 7.12 inches a much faster rate.

    While I have seen Hk 53 barrels with the 305 twist rate, I believe the standard twist rate on an HK53 barrel is 178.
    As to when the Hk53 entered the HK product line I think that is a question for Tony to chime in on.

    I had no idea 53s were ever offered without the 1x7 barrel. Can’t imagine how bad it would keyhole with a 1x12 twist out of a barrel that short

    Yes, it is a 178-marked barrel. I ended up buying two of those over recent years. One brings back bad GB memories. Seller had it listed on GB for $3k. Stupidly, I asked him if the barrel was marked 178? He came back and said yes, asked what that meant. When I naively explained it to him, the price went up $300. (The correct question I should have asked "what markings are on the barrel?" ..and nothing more) Live and learn. I am still happy I purchased it.
    LOL! That's something to learn from.
    How did he tell you price was going up though?

    He had it listed starting at $3k and it had gone through several cycles of not selling. When I answered his question (from my original question to him), it changed immediately to $3,300.00 without any explanation. Total ass, but I am happy with the gun.

    Can’t answer the question, but I can tell you that HK shipped both type barrels in the same model gun, in the same year. You can find 93s from the same year with either barrel. In some cases, they even had short barrels (under 16”) that had a pinned flash hider on them, in both twist rates. In one year, they shipped 93s with four different barrel configurations. I think HK made different type barrels for different customer requirements, and they made barrels in batches. Barrels left over from those orders got put in inventory for future builds. In the case of the 93s, they didn’t realize some of those barrels were a fraction of an inch under the 16” US requirement. Thus, four different barrels in one year.
