The @hmdefense HMB bolt is a new addition to my tool-less takedown AR from @drd_tactical. This rifle travels so I want it to be as reliable as possible and @hmdefense has beefed up the bolt by not having the cam pin go all the way through the bolt. Next up will be their Monobloc barrel! #igmilitia #ar15 #firearm #rifle #hmdefense #hmbbolt #47images #drdtactical #holosun #cmctriggers #magpul
