Tikka, Ruger, CVA, Winchester, lots of big names rifles come with a full sized length of pull and shorter barrel options. The Winchester xpr stealth is a hell of a good gun, comes in quite a few chambering a and is only a 16.5" barrel.
I also have a SIG cross, which is very compact and light, with a short barrel. Fits in the back of my extra seat for my quad nicely. And has been my go to rifle for hunting recently. Unbelievably accurate. Currently running 160 grain woodleighs in a 6.5 creedmoor chambering. Drops elk better than my 300 ultra mag.
Black Creek labs also makes some extremely short barreled rifles. I have a howitzer with a 9.5" barrel in 308. Handloads with 220 grain bullets are 1900-2100fps depending on powder, and extremely accurate. Planning on designing a load for a heavy accubond long range bullet, be a absolutly unbeatable rifle on size and pack ability. While having enough oophm for whatever needs to be taken down.
