Wake up Rednecks....another episode of As Rich's reloading world turns.....
So...my absolutely favorite AR build failed me yesterday. I finally got back to the loading bench and loaded some new powder (Accurate 2230) for .223 rounds. Set up the press and loaded 10 rounds on lower end of data. Took them out for test fire and fired fine, fully cycled, landed on target. Went to fire the second round and no joy. Re-charged the gun and out popped the new round....it had already fully chambered. Fired again and same. Third time I realized the gun was cycling fine, but the trigger was not resetting. I could fire after each shot only if I pushed forward a wee bit on the trigger to reset it. All 10 rounds fired fine, but no trigger reset. I grabbed a mag of factory ammo and same thing. Hmmmmmm.
This gun has a Rise Armament trigger...a relatively high end one. RA-536. This is an factory assembled drop in trigger. I absolutely love this trigger. Very short reset, very crisp, nearly no take up. This is a very fast trigger and to me (an admitted well experienced novice) a great trigger for my go to AR.
I opened the receiver and looked in and could not find an issue. I tested the trigger/reset by hand and same issue. Doesn't do it every time, but it would hang up. I could see the back of hammer being pushed back to far and catching on the .....sear? If I pushed the hammer fully back and down by hand...it would catch every time. If I pushed it just until it locked back, then trigger worked every time.
After a couple looks I saw a tiny spring and tiny set screw lying down in the bottom of the lower. I thought a detent and spring fell out from somewhere and could not figure how that was possible.
I looked at the set screw and the allen wrench side of it they had filled with clear hard epoxy to prevent anyone tinkering with it. I looked at the body of the trigger and apparently this spring and set screw is a fine adjustment to prevent the hammer from setting back (down) too far.
I went to the Rise Armament website and although could not get a schematic of the trigger assembly, I did see in the expanded "key features" details...the very last item: "Note: The center set screw should not be tampered with. Any attempts to modify the trigger will void the warrantly"
So I reached out to their help with an email with description and photos at 4:19 yesterday. To my surprise, I received a response this morning with them offering to repair/replace at no cost and they sent me a packing list to include free shipping both ways.
I am disappointed that my trigger failed, but pleased at the response from RA. I have read they had some issues with some of their products, but before purchasing this trigger, I saw nothing but good reviews and raves from users about this particular trigger.
So ended another day in the life....
and since I'm the only one using this thread....I keep humming "Dancing with myself" whenever I posting to myself here. Hah! Now that damn song is stuck YOUR head
