Nelson, the Moisin-Nagant rifle never had anything "tactical" as a factory add-on. ALL of this crap is after-market junk designed to remove your money from your wallet, painlessly enough that you don't call the cops. It's very flashy, designed by its gaudiness to attract the people who have money to burn and who don't know any better. Think of it as being rather like swapping beads and shiny things to the Indians and walking away with Manhattan Island.
Military rifle stocks are designed over a period of years into their final forms. In the case of the Lee-Enfield rifle, this process began with the introduction of the Remintgon-Lee Rifle in 1879. The British liked the basic bolt system and the magazine, but they already had the Martini in production and so could see the advantages of a 2-piece stock.... so they modified the Lee action in such fashion that said 2-piece stock could be used to advantage. Then they built the rifle, first in a .402 (likely half a dozen specimens) and then finally in the new .303 cartridge which the Royal Laboratory had designed with input from Major Rubin. Over the following years the 8-shot magazine gave way to the 10-rounder, Metford rifling gave way to Enfield rifling (also invented by Metford, by the way), the long Rifle and short Carbine combination gave way to a single Short Rifle, charger-loading was developed, a lighter barrel was introduced, the Cordite was modified to a much-less-erosive type..... and the Rifle, Short, Magazine Lee-Enfield Mark III was approved for manufacture at the end of January of 1907.
By that time it was PERFECT. The stock protected the hands of the shooter, it kept the sights well visible and usable when the barrel was good and hot, it provided a very solid platform for the Bayonet..... and it rebalanced the entire assembly into absolutely the SWEETEST bayonet-fighting combination ever developed, anywhere.
So the stock on a proper Lee-Enfield as absolutely as TACTICAL as they get.
No PLASTIC abortion of a thing can possibly fit the role as well.
