The Midwest Industries side folding brace solves the compact storage problem with a 4140 steel mechanism that folds your pistol for transport while maintaining rigidity when deployed. This brace works well for vehicle storage where every inch counts, range bag transport of AR pistols, and anyone needing a proven folder that locks solid in both positions. The full-length locking lug and steel clamp provide strength that aluminum folders can’t match, while 5 QD points give sling mounting options – bringing heavy-duty folding capability to Picatinny-equipped pistols with configurable left or right-hand operation.
Note: Adds 9.125″ to overall length when extended, only 0.75″ when folded.
