The Magpul ASAP ambidextrous sling mount adapter for AR-15 and LR-308 carbines is a no-nonsense solution for shooters who need to transition their rifle between shoulders fast. Built to replace your stock receiver end plate, it gives you a full 180° of unrestricted sling movement—letting you swing your rifle from one side to the other without binding, snagging, or fighting the sling. That flexibility matters whether you're navigating tight corners, working around barricades, or adapting to cover in the field. If a shoulder injury sidelines one arm, you can pivot the rifle instantly and keep fighting. This is the kind of upgrade that costs almost nothing to install but genuinely improves how your gun handles in real-world shooting.
Installation is straightforward: remove your factory receiver end plate and bolt the ASAP in its place. No receiver extension, buttstock, or sling changes needed. It's compatible with any single-point sling that uses a quick-release snap-hook attachment, and it fits both Commercial and Mil-Spec receiver extensions—so your existing setup keeps working. The adapter itself is cast steel with a 1/8" thick link ring, finished in mil-spec Parkerized manganese phosphate for rust and wear resistance.
Magpul engineered this for AR carbines that demand practical, modular reliability. Whether you're running a duty rifle, a hunting carbine, or a range gun, the ASAP is a low-cost way to add tactical flexibility without complicating your platform.
