Hey there forum! Never owned airsoft and looking for M4 with RIS foregrip rails. I thought I had decided on one of the Lancer Tactical versions but can't seem to find any currently in stock for Christmas. I'd like a metal gearbox from the get go but figured on other upgrades as money is available. I can go up to 150 but is there much difference in 100-150 or should I just stay around 100 and upgrade in the future? Playing in the woods out back as there are no fields in the area.
