Love it! functions great - Phase 5 Weapon Systems Inc Oversized Magazine Release AR15/.308

The shape of this mag release button is far superior, IMO, than any other extended/enhanced mag button that ive ever used. I've used Manticore, Armaspec, SI, & a couple others. Ergonomically, this one by Phase 5 is my favorite hands down. The size & shape make hitting ur mag release much faster & easier, especially if u get it to replace a milspec one. I got it in black. The finish is a lil shiney, but looks good IMO. Manufacturing quality is great & installation was very simple. I used this button paired with an enhanced mag release spring from railscales & the difference compared to milspec is night & day. Ik its not a vital upgrade & most people prolly wouldnt care, but if ur into making ur rifle custom & u like paying attention to the small details, this button paired with a quality spring is right up ur alley.
