The muzzle device reminds me of the barrel harmonics “tuners” that were a thing at one time. Along with that the shooter could adjust the heft and balance by placing a weight somewhere along the bottom rail.

[@wilsonlaidlaw]

Ian, I believe the "thing" on the front of the barrel was a barrel resonance compensator. Barrel resonance was a serious topic in the 1990's and various devices were being offered by different manufacturers such as Browning, Remington and Wetherby. I don't know if in real life they made any practical difference.

Some rifles have weights on the front to control barrel harmonics as a function of increased accuracy. Is it heavy under that front sight?

[@matsimento]

yes, pretty sure it is a barrel weight, for balance

[@AsbestosMuffins]

could have been a compensator-to-be but not actually drilles depending on how finished this prototype was

[@LexsLavrov]

Definitely barrel weight.

[@Skuggan84]

harmonics balancer was my thought as well.

[@ML-eb4rm]

You have to rise the front sight to match the line of sight (look at a G3 or the civilian versions). Far more simple and sturdy to just turn a “riser” with a dovetail than constructing a whole new front sight. Doesn’t mean they also tweaked barrel harmonics or corrected barrel length for this “weight”.

Muzzle device is to dissipate heat mirage to minimize you seeing it in the optic

Regarding the device at the end of the barrel, you may also notice a similar device where it exits the stock. I believe they are harmonic dampers, designed to keep the barrel from flexing as much after a shot, allowing for a more accurate second or third shot in quick succession.

That Anschutz rail in the fore-end is meant for a handstop and sling and, as someone pointed out, it has an Anschutz butt plate.

[@elonquemattheson6151]

The big black ribbed bulge on the front is a barrel vibration tuning weight. When you fire a gun, the barrel vibrates, and just like a vibrating string it has a shape that can be predicted and tuned using weights. Those vibrations are mostly on a plane perpendicular to the ground, so tuning them changes the vertical impact point. Not all ammo is perfect, and the gun isn't perfectly consistent either, so there's a variation in muzzle velocities which causes a variation in the vertical impact point. If the barrel is tuned just right, it's possible to make it so that the barrel points slightly upward with slightly lower velocity ammo so that the point of impact can be consistent. www.geoffrey-kolbe.com/articles/rimfire_accuracy/tuning_a_barrel.htm

[@nigelft]

So basically, instead of the barrel being a tuning fork, it dampens out the harmonics to not only improve PoA, but especially PoI ... ... or am I missing something ...?

[@7thdivision]

that one looks really nice, too bad they don't sell em

[@Fuddleton]

The end piece on the barrel is I assume a counterweight. The you can tune out certain resonances from barrel harmonics with a tuned weight on the end of the barrel. It may also just be a heavy duty attachment for a front sight, and the barrel blank just didn't have military front sight provisions.

[@tielemaniak]

You are in the HK grey room.... and you ask us for info on the SL7 match? :'-) Damnit, you're in Walhalla and you're asking Joe instead of Odin. That's not how it works ;)

[@elliotthebastard9418]

The thing on the end of the barrel looks like a heat sink to stop the barrel warping when it heats up. It would make your sights stay in exactly the same position every single time you fire it, even if you're in a competition where you're firing tons of shots.

[@slappy0079]

I believe that the muzzle device attached to the end of the barrel, as well as the grooved piece near the breech that appears to be a barrel nut may have two purposes. 1. To dampen/improve barrel harmonics. 2. To dissipate heat. I wonder if the engineers behind the rifle's design had reason to believe POI/POA shifts could occur no matter how small with rapid fire from the semi auto rifle. It would make some sense to make every attempt to minimize and prevent vibrations at the more critical junctures, it appears that is what was attempted there.

The weird device at the muzzle could be there as a "rail system". Looks like the front sight is actually oriented and mounted in the grooves, maybe they thought about using this also to enable switching out front sights (for whatever reasons) or to mount stuff like lasers? Although it seems to be a really bad idea to enable the user to put random stuff at the end of the free-floating barrel of your precision rifle...

[@nikolai5884]

Ok, im kind of guessing here. But could it be H&K's attempt for a new rifle for the Norwegian DFS in the late 80's? The Sauer 200STR was chosen in 1990. There were alot of different standard rifles in consideration, including the Kongsberg irg-m85 rifle with sideloaded magazines(not the Krag Jørgensen), Mauser m86 and a variant of the Steyr SSG. And up til the AG3(G3) the DFS has used the same rifle as the ones issued to the army, so that a match G3 would be a candidate would make sense to me. The rail in the front is for a sling and the buttpad is adjustable up and down.

[@jsquinlan]

What I would like to know is whether they were able to improve the trigger? My SL-6 has a Rube Goldberg affair for fire control and even William’s Trigger Specialties won’t touch it. It’s not a terrible trigger but it ain’t great for a precision rifle. Did this SL-7 Match get tuned up?

[@Mildcat743]

Maybe the ribbed section under he iron sight is meant to reduce heat mirage at the front sight?

[@afnDavid]

Would like to see more guns that are specifically made for left handed shooters. It does look like it is possible to change which side of the stock that cheek rest mounts on.
