The reason I chose the RSA was because I already had one that used to be on my H&K UMP. The second reason is that it has an incorporated quick release mount, so if it fails, I can just dump it and run the irons. Light as hell too. I’ve run it through many shotgun classes with zero issues.

In the pic, what you’re seeing is actually a rubber cover, but yes the scope is made of fiberglass reinforced nylon. The same as the optic that comes stock on the H&K G36.

Hensoldt RSA. Has a quick release mount incorporated so you can dump it if for any reason it fails. It also runs on both solar and battery power. The one in the pic has a rubber cover. Without it, it’s much slimmer.

From somebody that 3D prints a lot of parts, that is definitely not one you want to do. There’s no filaments that can handle that.

I had the exact same setup and I didn’t need to swap the tube. Just swapped stocks.

I have seen it done. I asked the guy how he did it but wouldn’t divulge the state secrets. Not even what model the stock was for. ?

I’ve had the most success with the Federal TruBall. You can get it with different velocities.

Merry belated Christmas! I had disconnected from the internet for a few days.

I had the Hayl rail and the feel was great, but like you mentioned the set screws was an issue. At the time there weren’t any better options, but that changed when Briley and Agency came out with their Mlok options. I ended up getting the long Briley rail. They have a shorter one that is the same size as the factory handguard , but I wanted the longer one so my light sits as far forward as possible. I couldn’t be happier with it. It’s rock solid yet removable with no tools. The endless amount of Mlok slots makes setting things up to your liking easier.

After two very intense training classes, my setup has held up perfectly. The level 2 class really pushed us to try every possible scenario and shooting position under the sun. That also helped confirm that my setup works well in less than optimal circumstances. Couldn’t be happier with the Briley long handguard. It helps put the light much further forward which is optimal. The Federal Flight Control 00 buck in the M4 practically performs like a slug out to 15 yards. At 30 yards I was still getting all 8 pellets in the “A” box. Federal TruBall 1300 fps slug is nearly as accurate as shooting with a rifle. I got solid reliable hits out to 100 yards. The faster versions of TruBall slug can probably reach further. Between the two classes and a bunch of training and testing before the classes, I have experimented with a bunch of different ammo. In the proximity of 5000 shots. My conclusion is that anything that is faster than 1250 fps runs reliably 100% of the time. 1200 fps runs 50-75% of the time depending on manufacturer. Even slugs at 1200 don’t cycle reliably all the time. The golden number is definitely 1250 fps. The more I train with the M4, the more I fall in love with it. My only beef with it is the pistol grip, but without having a shorter option of the field stock, this is it for now

It’s from GG&G GG&G M4 QD mount

My collection of G36s that I have built over the years.

If we’re adding FDE weaons in the mix, I can definitely contribute.
