I received the stamp for my Arsenal SLR-104UR (krink chambered in 5.45x39) a few weeks ago and just received the rifle back from getting it engraved. Tonight I cut the barrel to the proper length. I still have to crown the barrel to finish things up, but here it is the way it should be.

Good Question. Even though I drilled the gas port hole smaller than advised (less than 3mm) in my SLR-107UR (7.62x39 krink), I found that it will still eject spent cases with plenty of force even without a booster attached. So, I'm going to see how this one runs without a booster. My thinking is that if it runs without one, then all that I'm really accomplishing by using one is pounding the carrier in to the rear of the receiver harder. If it runs fine without a booster, then I'll just get some sort of flash hider for it. I'm actually hoping that it ejects sluggishly without a booster so that I need to use one because I like the looks of having one installed. We'll see.

My 104UR SBR runs fine without a booster. I have a cone type booster on it now and it definitely still feels overgassed (more than the normal overgassedness for an AK) with it on, but not bad without. Eventually I'll put a flash hider on it as I'm not to fond on the rifle beating the crap out of itself.

I've even contemplated buying a new gas block and going to work on it to make it adjustable.

New to this forum and this is my first post. I have an Arsenal SLR 106u (223) that I want to have SBR'd.
Have you shot it enough that you're sure it's 100% reliable? Mine was unreliable and Arsenal never could fix it. I actually had an approved Form 1 that I was able to get voided and money refunded because I never chopped the barrel. I wish it had worked, because a krink in 5.56x45 would be great. I have a Yugo M85 SBR, but it's heavy.

Need you opinions...

I have the option to get a SLR104-54.

Love the look and feel of the SLR104-54, but I live in a non-SBR state.

I understand the standard 16" barrel is really overgassed and I worry that continued use will wreck the receiver.

Is it worth buying the SLR104-54, knowing it is highly unlikely it'll ever be set free to its true form (SBR'd)?

Also, if I do decide to pull the trigger, would the Wolff spirngs prevent damage to the receiver?

Or, would it be possible to open up the gas port somehow to reduce the overgassing?

Thanks you guys.

It's not always about being practical. If it was, I wouldn't own most of the guns I have. Given your forum name, it's obvious you like the rifle. Once they stop making them they'll be near impossible to find and the price will go through the roof. I'd say that you should get it. Yes, install a heavy recoil spring and perhaps a recoil buffer. Shoot it and just keep an eye on the rear trunnion and the rear of the bolt carrier for damage.

Yes, but you'd have to remove the front sight/gas block, weld up the gas hole, redrill it to a smaller size and then reinstall the front sight/gas block. What would be the correct size to redrill? Who knows? You might actually get things back together and it be too small or still too big. Personally, I wouldn't mess with it.
