Smith & Wesson M&P Sport II Handguards vs. Magpul D-60 Magazine Dump (HD)
This video tests the durability of the Smith & Wesson M&P Sport II's polymer handguard under extreme heat conditions by performing a 60-round magazine dump using a Magpul D-60 drum. The test reveals some melting and deformation of the handguard, indicating its limitations under sustained rapid fire, though the rifle remained functional. The gas tube also showed discoloration due to the intense heat.
