Expanded Railway Rifle Mods This is a simple little mod, which should be expanded upon as time passes, which adds a bunch of new mods to the Railway Rifle, allowing you to go from mid-range carbine to long-range sniper, point-blank powerhouse to oblique bomb launcher.The Mods
Flechette Launcher
Launches a bundle of five Railway Spikes in a single blast. Powerful, inaccurate and often very messy, it's a brutal close-quarters weapon.

Required Perk: Gun Nut (Rank 2)
High Pressure Receiver
Sacrificing a high rate of fire for excellent range and accuracy, this receiver enables the Railway Rifle to be used far more effectively from long range.

Required Perk: Gun Nut (Rank 2)
Explosive Spike Launcher
For when you just want to pulverize everything in sight, Explosive Spikes detonate after a brief delay when striking a solid surface, but deactivate if they hit an enemy, allowing for the explosives to be collected and re-used in more favorable conditions.
