I have a KWA LM4 for exchange. I have the regular stock as well as a Daniel Defense and a PDW collapsible stock. The stock guard was replaced with a G&P MOTS keymod rail. The barrel is two piece and will come with both suppressors. Back up irons sights are included and I have a variety of other optics to negotiate with. I’m looking for other gbbrs (preferably hk 416,417, or anything G28.) I am open to other offers and have additional items for the right offer. For example a we Apache gbb mp5k.
