The FD338 is an American semi-automatic sniper rifle manufactured by F&D Defense. It is chambered for the .338 Lapua Magnum cartridge and is based on the AR-15 platform used by the M16. It runs on a variable tuned gas pull system and has a maximum range of 1,500 yards (1371.6 metres).
— In-game description
The SR338 is a semi-automatic Sniper Rifle introduced in the Battlefield 4: Naval Strike expansion, and is the only semi-automatic sniper rifle in the game (aside from the M82A3 Battle Pickup). It is unlocked upon completion of the Always Deadly assignment.
The SR338 differs greatly from most sniper rifles in the game by sharing many qualities with the DMR class of weapons, having very similar stats to weapons such as the RFB, Mk 11 Mod 0, or M39 EMR. However, unlike these DMRs, the SR338 is equipped by default with an 8x Rifle Scope and can unlock other high-power scopes.
- DICE stated in a blog post that DMRs would not receive long range scopes due to balancing issues despite players wanting them to. The SR338 was added to the game soon after and appears to be DICE's way of giving a DMR long range scopes whilst still keeping it balanced.
- Due to a bug, the SR338 third-person weapon model appears much smaller than normal. A similar issue affects the AR160.
- Previously, the bolt animation occasionally failed to play during rapid-fire with the SR338. This was fixed in the Fall 2014 patch.
- The mastery dog tag of the SR338 features an ergo grip, even though it is impossible to get this grip for the weapon in-game. The grip just might be a bipod, or a bipod-grip combo.
- Along with the other weapons of the first three expansions for Battlefield 4, the SR338 actually has an in-game description, but it can only be viewed when the weapon is unlocked at the end of a round or if it is equipped in a gadget slot using external tools.
