Send a PM to AJCrowley. He may be able to give you that info.

I did measure it, and I don't recall the exact measurement, but I do recall thinking that I'd be able to shorten the barrel to 18.5" (shortest you can go while maintaining non-restricted status), and the length of the rifle still wouldn't be an issue for the non-restricted.

If that answers your question, great, if not, I'll get an accurate measurement for you later.
 
SL8/ G36 Tools: Barrel wrench and trunion rod.

These are used together to properly remove and re-install the barrel. The rod takes the pressure off the receiver so that the trunion is not separated from the receiver during torquing. Factory spec is 66 ft-lbs. Most people doing barrel changes only go to 45 ft-lbs.

There are some available here: (contact brn2xl on HK PRo)

Thanks for the info. I just checked the thread pitch on the SL8 handguard and it is M5X0.8. I'll try to find out the pitch on the YHM stud, hopefully it is the same (cheaper!!!). If not, I'll just get a #2 adapter.

OK, I finally ordered this stud from Fabsports ($0.95) and I can confirm that it has the same thread pitch as the SL8 handguard inserts. It is an inexpensive alternative for installing a Harris type bipod.

You will need to add a small washer as the threads stop about 1mm before the base of the stud. It also helps indexing the stud.

Hi everybody!

I have a small question! Sorry if it sound stupid, I'm a SL8 Newbee...

Can I put a 3 (or 4) positions Trigger Group (for full auto) on my Semi Auto SL8??? I'm interested by a lighter trigger and they produce a Sniper Lower...

Thank You for your help!

I thought the SL8 trigger pull was already way lighter than any of the military models?

Yes, the SL8 trigger spring is about two or three times lighter than the G36 trigger spring.

Out of the box: No. With some modifications: Yes. All you really need to change the trigger weight is a different spring.

If you think the 2 kg is too heavy, well then you are probably a weakling, because that is a common match trigger weight.

But seriously, the SL8 trigger is almost impossible to do any sort of "trigger job" on, the most you could do is lighten up the trigger spring itself through some skill in metallurgy or finding a lighter spring. The "sniper" lower is just a marketing ploy. Yes, it is a bit lighter than the G36 trigger, but the SL8 trigger is lighter still. Practise with with you have. It's a good trigger, you just need to get used to it.

Personally I prefer the heavier G36 trigger, it feels more assertive.

Don't take it personally. I used to think my girlfriend was ugly, but then I saw her sister. Same with the SL8 trigger. It may seem like it sucks, but then someone lets you try a G36, and you realize that the trigger you have is a lot lighter.

By the way!.. Maybe you already know this american distributor...

I think Wolverine Supplies (check the banners above) was the distributor of the HERA lower, and I also recall that ArmsEast dabbled in that at some point as well. Also PM blaxsun he may be able to get some of that in as he carries their pistol-carbine conversions.
LAN World I don't believe does any exports.

You have looked over the first post in this thread, yes?
 
:) I don't take it personnally! :)) You seem a funny guy!

I have already look on Wolverine website but I don't find any indications for HERA products... I will contact ArmsEst and Blaxsum. Thank for the info. I have to admitt I did not saw Blaxum info...

Best Regards
 
I talked to the shooting edge in calgary, they carry hera products and can order in a sl8 lower for around 500$ give them a call if interested

For anyone whose a 'thrify' as I have to be I was able to make these in about half an hour with some 3/4" metal rod and one inch iron pipe from home depot. 10 bucks all in. Not nearly as pretty but it works. Just copied the plan pic, scaled it on a work copier to the right size and glued it to the end of the rod. then it was just grinding out the empty spots with a dremel... done!

Same for the wrench... although access to a welder for about a minute helps with the handle:D

Good work. How long did you make the flutes in the trunion rod tool?
I'll need to add that tool spec to the first page.
Click to expand...

All of about 5 minutes. It took longer to cut out the stencil. Never was good at keeping it between the lines... on pretty much every level:D

Normally I wouldn't mind buying it direct from the guy who makes them, he does really nice work. But he's stateside and it's just a PITA do deal with anything over $100 Cdn.
 
Hi!

Still unsure if I will buy an HERA lower (with a Magpul stock) or a real G36 FBI Lower with a Stock Block conversion and the real G36 stock...

At the end the price is similar!

Did you know if HERA lowers are reliable??? I have use photoshop to see what my SL8 could look with the HERA lower and a UBR Stock... And I like it...

But for a more common SL8/G36 conversion, anyone know if the SL8 Stock Kit from "Top Notch Accessories, Inc" are reliable too???

Thank You!


HERA + UBR


G36 folding Stock

The "reliability" of G36, HERA, SL8, and all other lowers for the G36/SL8 is exactly the same, provided that the internals are installed correctly. The HERA is the heaviest solution. It, plus an UBR, might counterbalance the heavy barrel nicely.

How tall are you? (Choose one: Shorter than Sarokozy, taller than Sarkozy but shorter than Obama, or taller than Obama)

Basically, length of pull-wise, the "stock-block" conversions are comfortable for Obama and taller. Between Obama and Sarkozy can get away with a "stock-block" and a C-length stock, and anyone shorter than Sarkozy will be best served by the HERA conversion, at the cost of an extra kilo of mass added to the firearm.

There are no "ideal" stock-block or HERA arms conversions. The only "perfect" conversion without the stupidly long length of pull or the body-builder training mass uses neither of the solutions you are looking at, and is up on the EE right now.

The biggest problem with the SL8 is that it is heavy. It's heavy due to the heavy target barrel, and bolting on block of aluminium and possibly even AR stocks does nothing to make it lighter than the 4 kilos it weighs by default. The G36 manages to shave off 400 grams, but that is including the dual optic, so in reality, it is even lighter than that. It accomplishes that by only having a lighter barrel and a skeleton stock, being the only significant differences between the SL8 and the G36.

So it's up to you what you want, either way any running-and-gunning, three gun matches, service-rifle, or any other competitive non-bench, non-prone shooting will increase your muscle mass, and make that trigger seem not so bad after all :).
 
Thank You for the "data"... I'm more like an Obama... :)

But is it possible to modify the barrel??? Not in lengt but in thickness??? Is it illegal? I think it's illegal to change the caliber or the lengt... But maybe it's ok to change the thickness...

I don't want my non-restricted SL8 to become restricted...
