That Pic is of a Mini 14 with a folding stock. The A team used the Mini 14 GBF
it has a flash hider and bayonet lug with front sight around the middle of the barrel. The ranch rifle is a little different from the Mini 14, it has a scope mount made into the receiver,the sights are different and the bolt is a little different to keep the brass from hitting the scope. The Mini has to use a side mounted adaptor to mount a scope.
The Mini 14 comes in different calibers, 223Rem/5.56 and 222Rem.The Mini 30 is 7.62x39 and the Mini 6.8 comes im 6.8 Rem.
These rifles are great for an all around rifle. They were made to throw into a truck or tractor to have a little protection while working on the ranch or farm.
They can do about anything from holding off bad guys and varmints to plinking cans. They are very relieable and are cheap enough most people can afford one. They were designed in the 1970s and are not TACTI COOL, but they do everything they were designed for. Ruger has impoved the accuracy in the newer models and they will compete with all semi autos now including the AR. They do not use the same operation system as th AK 47. They use a improved op rod driven gas system similar to the M1 Grand and M14 not a gas piston system like the AK. That's why the old men call them baby grands.
Most of the problems you hear about with reliabilty is due to bad magazines
I hope this helps.
