The ET Arms PlumCrazy Gen II Complete Lower Receiver w/ M4 Buttstock is engineered for the acceptance of mil-spec components and works on any AR-15 upper receiver!

Milled from a proprietary variant of glass-filled nylon-6, the PlumCrazy multi-cal lower receiver is more resilient to damage than traditional aluminum lowers. Durable & lightweight — with exceptional structural integrity and excellent chemical resistance — these ET GEN II receivers have been proven on training ranges with round counts of 50-97k cycled through with no issues.

The ET Arms PlumCrazy GEN II AR-15 complete multi-caliber lower receiver — continues to exceed expectations and redefine the standards for what an AR polymer lower receiver can be.

• Polymer buffer tube with 6-position collapsible/adjustable stock
