MX10
Valmet M78 7.62x39
Type 81
VZ-58/CZ-858
Not gonna lie about the MX10
The best overall gun in my opinion is the VZ-58/CZ-858. its light and probably the most accurate followed closely by the Valmet M78 but it is a lot longer and heaver being based off the AK RPD receiver. The barrel is a lock thicker on the Valmet so after a long stringer of ammo it may hold its accuracy better than a VZ but never checked that. Most of the SKS's, type 81, VZ 52 seem shoot about the same average groups with military ball ammo. The MX10 which I was quite hopeful for is nothing to write home about in terms of accuracy. It does not shoot any better than the guns I just mentioned. We tried two different MX10, with approx a dozen boxes of different civilian and military ammo. Its a 3" gun AT BEST. Every group that seemed promising with 2-3 rounds close together would open up with 1-2 flyers. I still like the gun, for offhand shooting at 100 yards at steel you can't miss but a long range DMR it is not. I still own it, I enjoy the AK mag compatibility, and cheek weld with a red dot. I took the scope off after accuracy testing cause in my opinion this gun isn't accurate enough to warrant needing a scope and decided to just keep it light(er). It is well machined, and the bolt movement is extremely smooth. The trigger is far too light, like you can easily bump fire accidentally and send off two rounds, maybe a bonus for some, but annoying to me. The changing handle occasionally gets loose and launches itself into the grass. Bartok informed me of the Oring trick to keep it secure and that seems like a reasonable fix to me. Should it cost what it does? No, but IMHO then a type 81 should be more like a $600 gun in our market based on the chinese SKS like quality. I wish it had a lighter barrel, how much worse can the acurracy get, give up on that and go lighter if its a lost cause? And a lighter receiver with more metal machined off and a heavier trigger. If the fix these issues on the next generation they may be worth getting, only buy it now if you can live with these deficiencies
