Nice rifles, I've owned 3 of them. Should have a year of production stamped on the socket just like the Brit and Australian MkIII's along with the Model.
Most every one you see is a Model 2A1.
They produced for a short time a Model 2A before those. The only difference I can think of is the rear sight graduations and elevation ramp contour but they bring a bit more $$ from an Enfield collector.
Designed specificly for the 7.62Nato round. Not a rework of the older NoMkIII rifles. Different steel used in the receiver and bolt.
Most have a heavy black enamel paint finish. Some a parkerized finish and some a nice rust blue. Sometimes either of the latter two will be lying in nice condition underneath the heavy coat of enamal paint.
The stocks are a type of mohogany. It can be a bit brittle when handled off the rifle, but they seem to hold up well. The butt plate is cast aluminum in place of the brass (gunmetal) used on the No1 rifles.
They are cal 7.62Nato,,and it is a different cartridge from the 308Winchester. Using commercial 308Win guages to check headspace will most certainly show the rifle to have grossly excessive headspace. Use 7.62Nato guages when checking HS.
If you don't care for the higher position of the butt stock on the 2A1, a butt stock from a NoMkIII will fit and bring the comb back down to the latters profile. The difference is only the position the stock bolt hole is drilled through the wood,,lower on the Ishapore.
Magazine will hold 12rds, though they often adv as a 10rd. Originals are hard to find but there are repros around. As with the other Enfield bolt rifles, the mag was not meant to be changed in reloading. Instead, 5rd chargers used to replenish the mag while in place.
US M14 Rifle 5rd chargers will work in these.
