Assuming we're talking about ranges under 300 yards, and an urban/suburban environment, I would no doubt go with the rifle I've had the most experience with, an HK416, although I'd have to go with the 10.4" barrel as opposed to the 14.5" that I've actually owned. As easy as it is to swap out the barrels on these rifles, I'd no doubt like to carry a 14.5 or 16.5 inch barrel with me, but the 10.4" barrel makes the weapon much quicker to get on-target IME, as well as having more than enough range for an urban or suburban environment. I do wish the weapon was available in 6.8mm, but in a ZPAW, there's no doubt that 5.56 would be much, much more common.
My Number One Go-To "Long-Arm"
Rifle: H&K HK416 D10RS 5.56mm
As far as "setup" is concerned, I'd probably stick with what I know:
- SureFire M900V 150lumen LED weaponlight/vertical foregrip (I personally owned the M900A, but the LED "V" version has 10x the battery life... better when batteries are scarce, although you are down to 150lumen from 225)
- EOTech Model 553 Holographic Weapons Sight (1100hrs continuous operation at highest brightness before needing new batteries) with an L3 G23.FTS (flip-to-side) 3x magnifier (the G23 offers an increase in range if needed while still allowing for both eyes to be open, and takes 1-2sec to move out of the way while transitioning indoors)
- MagPul UBR Stock - Utility/Battle-Rifle (the 7-position adjustability along with the small storage area in the back, say for extra batteries for lights/sights, makes it a win-win for me)
- Advanced Armaments (AAC) M4-2000 Sound Suppressor (not just for use with subsonic rounds, but so that I can fire anytime needed, inside or out, without hearing protection; also, it can easily transition to other 5.56 weapons)
- Insight Technologies AN/PEQ 2A Visible/Infrared Laser Pointer and IR Illuminator (the IR ability is fantastic if I would be able to get my hands on a set of high-end military NVG's)
- 12x MagPul EMAG MagLevel 30rd 5.56x45 Polymer Magazines with PMAG/EMAG Ranger Plates installed (open slit on side makes it easy to visually estimate how many rounds remain, while the ranger plates make reloading much faster)
- Troy Front and Rear Low-Profile Folding Battle Sights (back-up iron sights designed around the HK416 and EOTech sights; fold out of the way when not in use, but a simple button push pops them up; good for when the world does eventually run out of batteries)
- MagPul Enhanced Aluminum Trigger Guard (for use with full-fingered gloves and/or cold weather operation)
As far as distances 500m and beyond, such as rooftop sharpshooting in an urban environment, providing precision cover fire for teammates, or any other situation that would require a longer barrel, a heavier caliber, and a more stable platform, I'd no doubt go with a modified M14. Although I loved my L96 in .338 lapua magnum, the M14 uses the much more easily found .308 Winchester, and fires semi-auto as opposed to the bolt-action L96, making follow-up shots much easier and that is pretty much the point of an urban "precision rifle" compared to a "sniper rifle", I do believe. Wouldn't make much in the way of modifications, as it's pretty well loaded from the factory.
Rifle: Smith Enterprises M14 SDM 18" Chrome-Moly Barrel in 7.62mm
Setup:
- SEI Quad-Rail MIL STD-1913 System
- Sage International Modular Collapsing Stock w/ "Sniper-style" Pistol Grip
- Leupold Mark 4 4.5-14x50 LR/T M1 Mil-Dot Scope with the Barrett Optical Ranging System integrated ballistic computer (automatically calculates bullet drop based on temperature/humidity/wind speed and direction/etc, making varying-ranged shots incredibly quick and easy)
- Harris Compact Folding Spring-Loaded Bipod
- SureFire M600C LED "Scout" Weaponlight
- MagPul Folding Vertical Foregrip
- SEI M14DC Sound Suppressor with quick-detach and Vortex Flash Hider
- MagPul PMAG 20rd Polymer Magazines with Ranger Plates
(It would look something like this, although with a different scope/weaponlight/foregrip/magazine:
