I just discovered the SL-7 model.
Is the rifle reliable for recreation target shooting and hunting?
Does the charging handle come back during fire? Or stay put like an AR.
In the video referenced above, the mount used is not the HK-05, but instead is the B-Square, which, although it has been discontinued, can still be found new and used for less than $100, usually about $50. Here's what it looks like: https://www.midwayusa.com/product/1008789744 (not available there now, so this should not be a posting violation here, I hope). It probably doesn't lock down as tight into the two receiver holes as the HK-05 does, but the video above shows him shooting good groups with it installed. Mounts for the HK300 are interchangeable with the SL6, SL7, 630, 770, and 940 rifles, which is why they're so cool.
These mounts were also discussed here previously, in at least one other place: https://www.hkpro.com/forum/hk-long-...770-940-a.html
Oh, and also, the SL6 and SL7 innards are the same as with the 630 and 770, as I understand it, and they definitely have interchangeable magazines. I shot my SL7 2 rounds, and it kicked far worse than any 30-06! The SL models are more like an M1, to me, whereas the 630/770/940 are more like hunting rifles in style.

Depends on your preference but they're perfectly handy for hunting. If you have mag restrictions for hunting they came with 3 round mags (I've got a 3 and 10 round mag).
As far as optics mounting, HK05 mount for a fair few pennies or the B-square mount as mentioned, OR there's the Contessa rail at Optics-Trade.eu that fits perfectly in place of a QR option. I've got mine paired up on ARMS #22H rings so the glass clears the rear sight.
Shooting surplus FMJ I was getting 1-2" groups at 100 yards.
I recently purchased an SL7, haven't shot it yet due to the covid shutdown but I like it very much.
As for the after-market scope mounts, B-square made one but it is the weaver style and some has only three slots. Sunoptics made one in picatinny style.
Both are discontinued but from time to time one will appear on ebay or gunbroker. I bought a B-square on ebay not too long ago for less than 20 bucks, guess I was lucky.
HK 05 is great but costs a small fortune.

I have one, nice novelty gun. It is probably the hardest recoiling 308 I have experienced and the metal butt plate doesn't do you any favors. The HK 05 mount is fairly limiting with respect to modern optical options because the optic can't have a left side turret for parallax, illumination, etc. I've had trouble getting much accuracy out of mine, but I have reason to suspect the previous owner may have bent the barrel slightly. It's something I need to look further into.
Hokey religions and ancient weapons are no match for a good blaster at your side, kid.
As Lerch641's post and picture above show, Contessa makes a picatinny mount for the SL7/770 (should fit all other HK rifles that take the QR HK-05 mount). I just ordered one, about $110 including shipping, coming from Europe, I think, but now I can't find that link. Many US resellers (Brownells, MidwayUSA, etc. etc.) also offer them, though the in-stock availability varies. It comes as a 0 MOA, or as a 20 MOA option for those who want to shoot > 600 yards.
bastardsonofelvis complained above that the HK-05 mount can't have left-side optical options, presumably because of the vertically positioned quick-release lever, but note that 1) the mount can be reversed and the release switch can be used on the right side, if that matters, and 2) there is a variant of the HK-05 mount which has the QR lever still vertical but at the rear side of the mount, instead of the middle side of the mount, just for this very reason. They're less frequently for sale than the standard HK-05, but they are out there. Contessa also makes a quick-release version for the HK770, with horizontally positioned release lever, as opposed to the vertically positioned lever on the HK-05 mount, to help with that issue, but the price is about the same as an HK-05.

I was about to order one at optics trade after I saw Lerch641's post. Great information BTW. However I didn't pull the trigger because it says on the website it is for 770/940, w/o mentioning any other models. I think it will fit the SL7, SL6, 630, etc. but I wan't sure. I sent them this question but haven't heard back yet.
I have an HK05, and a B-square, but the picatinny rail is appealing.
