This setup is specifically for use with the Griffin Armament EZ-Lok system.\u00a0 The male side of the EZ-Lok adapter is included with this upper and torqued in place with red Loctite.\u00a0 The female, suppressor side of the EZ-Lok, is not included but I do sell them separately.\u00a0 The suppressor seen in the pictures is not included either nor is an additional barrel.\u00a0 They are just for illustrative purposes.\u00a0 \u00a0No charging handle is included either as everyone seems to have their own favorite.\u00a0 I do sell the Griffin charging handles as well.<\/p>\n
While I do torque down the barrel nut, I do not thread lock or tighten the rail screws.\u00a0 I had 1 customer tell me the rail interfered with two lowers he tried.\u00a0 A Doublestar and a PSA lower.\u00a0 I sent him a prepaid label to ship it back to me.\u00a0 I dropped the upper on 3 different lowers, CMMG Glock lower, post sample M16 lower that was an 80% Tactical Machining lower and my MGI Hydra Lower.\u00a0 It dropped on all 3 lowers perfectly.\u00a0 I then paid for shipping a third time back to him.\u00a0 So now, I keep the screws loose so you can adjust to your lower accordingly.<\/p>\n","protected":false},"excerpt":{"rendered":"
