ar_quibsterMBUS 1.5 front zero held
Reviewed on January 20, 2026Verified with Build
Magpul MBUS 1.5 Gen 2 front sight has clear sight picture once deployed. Zero held through a 500 round day. Polymer is impact resistant - mine has taken hits without breaking. Standard A2 tool for post adjustments. Solid backup sight.
