Irish,,,the Practical stock was easy to put on,you'all need a small phillips for the recoil pad and a 13mm socket for the stock installaion,I prefer the Practical stock over the stock with the side sling loops.the heat shield is TRICK to install,fore arm mods are a must.the oversize bolt handle is the G&GG special,look at the Cals Sporting Armory site for mag extensions or E-Bay,,,,,,,,,,Happy Holidays Irish
