Fightlite Industries SCR Lower Receiver Features The Fightlite Industries SCR is a polymer lower receiver built to accept AR and M4 pattern magazines giving builders a familiar platform to work from when assembling a custom rifle. Its multi caliber compatibility means the lower can serve as the foundation for a variety of AR pattern builds rather than being locked to a single chambering. A crossbolt safety gives shooters a manual of arms they may already be familiar with from other platforms simplifying the learning curve for a new build. Polymer construction keeps the receiver lightweight which helps offset the weight of heavier barrels optics and accessories added further up the rifle so the completed rifle can stay balanced and manageable even as components are added. At 2.50 pounds the SCR lower is noticeably lighter than a comparable aluminum forged or billet receiver a meaningful advantage for builders chasing a lightweight overall rifle without sacrificing the strength needed to carry a serialized receiver through years of use. The Flat Dark Earth finish gives builders a cohesive color option for matching furniture and other FDE finished components elsewhere on the build so the finished rifle presents a unified look rather than a mismatched assortment of parts. A 13.5 inch length of pull is built into the receiver s design giving shooters a defined baseline for stock positioning during assembly and a consistent reference point as other components are fitted around it. Because the lower accepts standard AR and M4 pattern magazines builders retain access to the wide range of magazines already common across the platform keeping the project flexible rather than reliant on proprietary parts. For builders starting a custom AR or M4 pattern project who want a lightweight color matched polymer lower as the backbone of their build the Fightlite Industries SCR is available for sale at GrabAGun.
