Delta Armory Magazine Release Button M4 / AR15 / M16 — Black

Metal magazine release button for M4, AR15, M16 and SR-25 airsoft guns with a receiver body built to TM AEG standard. It replaces the stock component when worn, excessively loose or broken, restoring the release function to original condition without any modifications to the receiver.

The metal body weighs 30 g and delivers a more positive tactile response than the polymer buttons found on many entry-level airsoft guns: actuation is crisp and return to the rest position is immediate. The trade-off worth knowing is that a metal button transfers receiver imperfections more faithfully than a plastic one — if the receiver is damaged or out of tolerance, the new part will not hide the problem.

Stated compatibility covers the M4 / AR15 / M16 / SR-25 platforms to TM AEG standard, which account for the majority of AEG replicas in this family on the market. Before fitting, it is worth confirming that your receiver genuinely follows this standard, particularly on clones from smaller manufacturers that sometimes introduce undeclared dimensional variations.
