WE Tech Full Metal Lower Receiver for M4A1 GBB Airsoft Rifle - TAN
This M4 Lower Receiver comes with the components you'll need to build a WE Tech's M4 Open Bolt GBBR airsoft gun. The trigger assembly is ready to go right out of the box, a mil-spec buffer tube lets you to use your choiceof aftermarket rifle stocks (including from real steel brands like Magpul), and the safety selector switch allows you to choose to shoot in semi-auto or full-auto once you've install the upper receiver assembly. Additionally, just like an actual M4, the selector switch defaults into the semi-automatic position until you slide in a magazine and rack back the charging handle (once upper receiver is installed).
