Coming to this game, and doing what research I can about the lore (what little there is) and taking a look at the suggested weapons, I find myself rather surprised that there is a complete absence of any semi-automatic variants of this platform in game. To my understanding, the region of Chernarus is meant to be at least loosely based off of Czechoslovakia - So it is there I will begin my reasoning for many of the following points. Of all European states, Czechoslovakia may have the greatest number of civilian owned AR-15 rifles, reason alone for consideration, but not the only point. Czechoslovakia also has a local weapon manufacturer for the AR-15 series, via Luvo Prague, though there is also a large presence of H&K and Sig Sauer product as well. Even outside of this, since the fall of the soviet union, the AR-15 platform has quickly been taken up by a sport rifle among many former soviet republics. Though while not as prominent as more traditional rifles, the AR-15 still nevertheless is popular. There are of course reasons for this, not lest of which is the customization the platform provides. Lower receiver, upper receiver, stock, handguard, pistol grip, and more are interchangeable - with various rifle cartridges available for use without changing the whole rifle. These properties make it largely considered among the best - if not -THE- best for a post civilization/apocalypse/zombie scenario, in which you never know what type of ammo you may find commonly, or what parts you may find. I would propose the AR-15, and the M4 as an extension, be broken down into the following as a fully modular system: lower receiver (gives the name of the gun and differentiates between pistol, rifle, and M4/rifle auto) Upper receiver (designates the ammunition fired, accuracy, and durability.) The above two would be crafted together to make the firearm in question, and could be broken down afterward. Grip (different types of pistol grips with varied ergonomics - small accuracy difference) stock (different types, some easier to carry, some more accurate, some have storage.) Scope/sight handguard -with rail assembly: Left rail right rail lower rail 1 (secondary vertical grip, bipod, vertical grip w/ internal bipod, lower rail 2 while I would assume most of the calibers for the gun would be irreverent, I would still like to see 9mm pistol .22 LR 5.56 NATO 7.62 x 39mm as ammo types (each with their own magazines, in various sizes) upper receivers would have different barrel lengths: 8in (pistol) 12 in (M4/carbine/SBR) 16 in 20 in 24 in And then offer a gas system: either direct impingement or piston. (this could be a separate component, requiring the rifle to be fired in bolt action without.) while it is a lot of work, I see it as an addition for realism, and a way to drastically increase the ability to customize an individual's character via the rifle. It may not be something for the short term, but even if the realistic customization is not included, it still is a common sporting and law enforcement rifle that I feel should have a place in the game.
