The River Rain LLC M16A1 stripped lower receiver
- River Rain Premium M16 Series Forged Lower Receiver consisting of:
- M16 cut fire control pocket. (Ready for an SOT to drill the “third hole” and convert to a “post sample” or a DIAS)
- Lowers are machined from 7075-T6 forged aircraft grade aluminum
- Coating is matte black hard coat anodized Mil 8625 Type 3 Class 2
- Upper tension screw hole behind grip screw (threaded hole) to adjust any “slop” out of vertical fit between upper and lower (hardware not included)
- Caliber marking of “5.56 MM” but can be used with many different caliber uppers (300 blackout, 9mm, etc.)
- Compatible with all Mil. Spec. AR-15 components and magazines
- Safety selector markings accurate to the M16A1: SAFE-SEMI-AUTO

NOTE*** The River Rain LLC M16A1 lower receiver is not a historically accurate reproduction as it is an A2 profile lower receiver, with a “fence” around the the mag release button, is black instead of grey in color, and has all of the other A2 lower receiver profile alterations.
