The Heckler & Koch HK41 is a semi-automatic version of the Heckler & Koch G3 battle rifle; it was produced by Heckler & Koch for the civilian market in the 1960s. It is not to be confused with the similarly titled Heckler & Koch G41. Current status It is estimated that fewer than 400 HK41s were produced and even fewer imported into the U.S. for civilian consumption. Today, HK41s can sell for anywhere between $4,500 and $9,000 depending on the condition and the economy at the time. An original 1966 model with the push-pin hole in the receiver can sell for around $37,000. These are very scarce because most of them were used as hosts for full-auto conversions prior to the May 1986 machine gun ban. A full-automatic converted HK41/HKG3 can sell for over $20,000. Variants There are two models of the HK41: HK41A2: Fixed stock and semi-auto "SE" trigger group. HK41A3: Retractable 1-position stock and semi-auto "SE" trigger group. Versions of the HK41 (1962): There are 3 different date stamps from this year in the United States, all with differences. By far the most desirable, and also the rarest, are the 3/62. These models are identical to the G3 Automatic Rifle except for having a swing-down semi-auto "SE" grip assembly. It was able to be converted to a full-auto G3 by changing the trigger group and bolt, no need to change the location of the push pin or any of the other features. They were all marked G3. This is why it is the most desirable of all semi-automatic G3s, and they are also incredibly rare with less than 3 known to exist in the United States (known as Santa Fe "swing downs") still in semi-automatic form. Most were registered as full-auto hosts. Their value as full auto hosts is no more or less than any other G3, it is their value as a semi-automatic which is extremely high in comparison to other G3s, having sold on Gunbroker for over $20,000 on two occasions, matching the prices of full automatic G3s. It might be one of the only examples of a fully automatic transferable that is valued the same whether or not it is in the registry. 7/62 is the second most common date from 1962, and like the March labeled guns was marked G3. However, the push pin hole was moved so that a full automatic trigger pack
