I made the Almost Tier-2 mod, which used MSBS Grot as a bullpup version of K-PAC equivalent. But I honestly wanted a more consistent design.

So, I went and kit-bashed K-PAC into a bullpup. Then I realized that the vanilla K-PAC arts is very much not to scale, at least not to an IRL AR-15 pattern rifle. The magazine is way too large compared to the length of pull or overall length.

I eventually just accept the magazine being too big and use the length of pull as the reference length, assuming the K-PAC is a fully collapsed AR-15 equivalent at the minimum length of pull of 10.5". From that, I found that the Base K-PAC has \~13" barrel and the Range K-PAC has only \~16.5", which is kinda short for a purpose-built DMR-ish rifle, and it felt more like a long-ish general purpose rifle than a full DMR.

Anyway, I kit-bashed it into a bullpup: **R60A1 PAC-K (Personal Assault Carbine - Kruger)**. IDK what the actual meaning of K-PAC is, but I just want to meme it and make a bullpup of R10A6 K-PAC called a R60A1 PAC-K. It is hilarious if they use the same abbreviation, just switching places, because it is a bullpup.

PAC-K is a bullpup with a length of pull of 13" with the basic thin butt-pad and a \~19" barrel, which is honestly too long for my liking. But a shorter barrel doesn't have the railspace for the K-PAC UBGL. That thing is looong. I also squeezed down the height of the rifle to facilitate the modern C-clamp grip. But, that's only possible without a chonky UBGL. So, no C-clamp for grenadier.

The PAC-K with a suppressor is longer than a collapsed Range K-PAC (which is actually more of a GPR/Recce Carbine than a full-length DMR), but should be shorter than a Range K-PAC with butt-stock deployed to proper length. It looks a bit too front-heavy TBH, but there's no way to make it shorter without abandoning or changing the UBGL.

I might release the rifle as a mod later, but it would take the same niche as the MSBS Grot B, and I would absolutely replace it instead of keeping both, making the next version of the mod save incompatible. So, that will be after I finish my current run at the soonest.
