    Conversion Lower

    Posted by Grant on Apr 20th 2025

    Amazing product. Exactly what I needed to adapt my SCAR-H to shoot 5.56. Sourced a used SCAR 16 barrel and a new 16 bolt from MGW. Completed the lower with a Rock River Arms LPK. The 2-stage national match trigger, M3 PMAGs, and KNS Discarder cycles reliably. Recommend to use an extended magazine release button as this receiver is longer. I kept mine as “SCAR looking” as possible by using a Noveske/Magpul SSG safety selector and the factory A2 grip. Quality and fitment are excellent, get one if available! Thanks for addressing consumer demand where FN did not! Good work, Lingle!

    Awesome Product!

    fit and finish is great aesthetically and physically. everything about it is top notch and the simplicity of the lingle conversion (lower, bolt, firing pin) vs the factory FN cant be beat. the only draw back is disassembly. you MUST have the hammer locked and weapon on safe to prevent the hammer from falling and hitting the internal bolt catch lever. Its made of plastic and just the bolt moving forward from resting on the back of the carrier to contacting the plastic part is enough to break it. Other than that, i would highly recommend this product to anyone looking to be different.

    The lower arrived quickly and was packaged well Machining is excellent and the finish was perfect. Assembly was smooth and easy with all parts fitting perfectly. I used FN factory 16 barrel and bolt assembly.installed in a NRCH SCAR 17. Testing so far has been 100% reliability. .
