The Spikes Tactical Punisher Stripped Lower Receiver (part no. STLS015) brings Spikes’ well-known Punisher billet marking to a forged 7075-T6 aluminum AR-15 lower. Spikes finishes it in a black hard coat anodized finish and builds it to support multi-caliber uppers, so builders can pair it with nearly any AR-15 pattern chambering. It is also low-shelf and RDIAS compatible, giving trigger group flexibility beyond a standard mil-spec fire control group. This lower ships stripped, so a lower parts kit, buffer, and stock of your choice are needed to complete the build.
