Item # 131115 Style RPR-APAR600001C UPC 815421022315 Condition New Manufacturer [Aero Precision](https://www.kygunco.com/brand/aero-precision) Model M4E1 Hand Ambi Finish Black Caliber MULTI Weight 2 lb Action Semi-Auto ### Aero Precision M4E1 Stripped Lower Receiver - Anodized Black The M4E1 Lower Receiver delivers billet aesthetics in a forged package. This custom designed enhanced forging is machined from 7075-T6 Aluminum and compatible with all mil-spec AR15 parts. Aside from the visual upgrades this custom engineered design provides that challenge much more expensive billet options, several functional features have added to the lower receiver to simplify the assembly process for the at home builder. The M4E1 Threaded Stripped Lower Receiver is designed to pair perfectly with the [Aero Precision M4E1 Threaded Upper Receiver](https://www.kygunco.com/product/aero-precision-llc-apar700201c-m4e1-threaded-stripped-upper-receiver), giving you a billet looking receiver set at a fraction of the billet price. #### Features - **Threaded Bolt Catch Roll Pin** - Allows for simple installation of the bolt catch and virtually eliminates the chance to damage the finish during installation (pin included). 1/16" Hex Key required for assembly. - **Integrated Trigger Guar**d - Eliminates the possibility of breaking the trigger guard tabs by integrating the trigger guard into the lower, creating a stronger more rigid platform to build upon. - **Upper Tension Screw** - Allows users to fine tune the fit of the upper and lower receiver using a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver. - **Threaded Takedown Pin Detent Recess** - Allows user to easily install the Takedown Pin detent and spring with the use of a 4-40 set screw (no more launching detents across the room). - **Increased Magwell Flare** - Increased the flare of the magwell to aid in quick and efficient magazine changes. - Marked and milled to accept short-throw safety selectors, but will work with standard selectors as well. #### Includes - Stripped M4E1 Lower Receiver - Nylon tipped tensioning set screw - Threaded Bolt Catch Pin #### Specifications - **AMERICAN MADE?:** YES - **PLATFORM:** AR15 - **MATERIAL:** Machined from 7075-T6 forged aluminum - **FINISH:** Anodized Black - **MARKINGS:** "Cal Multi", "M4-" Serial Number Designation - **COMPATIBILITY:** Works with standard AR15 components and magazines - **WEIGHT(S):** 8.61 oz - **OTHER:** Rear takedown pin detent hole is threaded for a 4-40 set screw.

Awesome Lower! 3/2/2024 ** ** ** ** ** ** Andrea Hot Springs, AR Shipping was super fast. Aero precision lower is all there is needing said. Love aero precision parts. 4/27/2023 ** ** ** ** ** ** Verified Customer Great lower! 4/13/2023 ** ** ** ** ** ** Anthony Centralia, WA Can't find anything wrong with this lower, fits perfectly with its matching M4e1 upper and looks great. Threaded bolt catch pin installed and integrated trigger guard are pretty nice inclusions. 7/22/2022 ** ** ** ** ** ** Verified Customer Best stripped lower receiver with a very modernized and billet style but still mil spec compatible and has screws built in to make that pin hammering go away. Also has a tension screw for that wobble that comes with builds that’s a plus along with the built in trigger guard. Best bang for your buck or should I say build!!! 4/2/2022 ** ** ** ** ** ** Duane Perry Cumming, GA It was shipped on time. The price was better than any place I could find. Would buy again. 9/29/2020 ** ** ** ** ** ## More from Aero Precision ```json {"@context":"https://schema.org","@graph":[{"@id":"https://www.kygunco.com/#website","@type":"WebSite","description":"Shop KYGUNCO for firearms, ammo, accessories, parts, and outdoor gear at low prices with fast, easy nationwide shipping.","name":"KYGUNCO","url":"https://www.kygunco.com/","publisher":{"@id":"https://www.kygunco.com/#/schema/organization/kygunco"}},{"@id":"https://www.kygunco.com/product/aero-precision-llc-apar600001c-m4e1-stripped-lower-receiver-anodized-black#webpage","@type":"WebPage","description":"Shop KYGUNCO for firearms, ammo, accessories, parts, and outdoor gear at low prices with fast, easy nationwide shipping.","name":"AERO PRECISION M4E1 AR-15 Stripped Lower Receiver -
