Nice; please might i ask for the RCF carabine to get a gunbutt attack?
That's not very realistic. The stock is collapsible.
But you know what is realistic and never gets any attention?
A Bayonet on that RCF Carbine.
Frankly the Battle Rifle would be amazing with one too (the Infantry Rifle has a gunbutt attack). Then your melee character can use that and if they want they can Burst from 2 tiles away.
I noticed is the Combat Shotgun has a gunbutt attack but the sprite for the Trench Gun has a steel plate on the stock, which should be on the other one since its gunbutt strike is replaced with a bayonet. Also since the gun is already shortened (the action mechanism is moved back) the Trench Gun could have a proper bayonet graphic put on it like the Musket has, it doesn't need to look like the dagger itself.
Fun Fact:
IRL soldiers almost never use the Burst (Full Auto) function of their rifles, and generally speaking they perform Snap shots (rapid semi-aimed fire) ducking back and forth from cover.
This reminds me of the STG44 german rifle somehow, I dont think requests go here but that'd be great to give to Humanists/KKK to replace some of those Messers. Itd probably use Homefront Banana clips and be a more refined (higher burst accuracy) version of the Homefront Rifle.
