The new L1a4 Battlerifle was added to pfc vendors and sniper kits, it has two unique attachments, the carbon stock, which increases wield delay and weapon size in exchange for improved weapon handling, and the Ifts miniscope, which can be used while moving, and grants IFF like the smartgun or sniper rifle, it's got worse handling when wielded compared to the pulse rifle, but better when one handed, it can fit most attachments, on the barrel, optic slider, and has room for the carbon stock (haven't tested if it can fit the paratrooper stock yet). It has 20 round magazines, with extended and AP available through squad vendors and req
seems like a strange carbine type weapon, while its power is pretty underwhelming, the IFF might balance it out to be superb, making for easier firing lines where you have the bigger guns up front and a bunch of IFF guns behind them, we'll see how the meta shifts in response to this and the two new armor types. The sprite is reminescient of the british sten gun or the american grease gun, but does not have burst or automatic fire, and as far as I can tell cannot fit underbarrel attachments.
If i got any info wrong let me know, and let me know what you think about this new weapon in general, personally I think that it's really cool that pfcs now have access to a decent medium power IFF weapon, because congested firing lines are the bane of marine sanity when urist mc cuckshot is standing three feet away and is feeling blood thirsty. From what it seems it wouldn't be able to go toe to toe with the pulse rifle, which makes sense as it has burst fire and better accuracy when wielded, and it can't go ham on a shotgun or smg in very close quarters due to the amount of damage it puts out, so it is a semi shitty jack of all trades, but the IFF and badass sprite when the new scope and stock are attached makes up for it, also the IFF only works (so I've been told) while scoped in, so keep that in mind.
