AR-15 trigger kit

[DocMedic]

where do I find low priced, decent 3lb single stage trigger kit for a AR-15

If your still looking at triggers, you can get one done by Bspring for a good price, it does involve using your stock trigger though. I had it done, and I must say it breaks clean and smooth at 3lbs.

Any one from the Bailey area that can show me how to take out the trigger/Hammer assy so I can send it off for a trigger job??

Everything you need to do a detail disassembly is built-in as part of your AR-15 rifle.

Make sure the rifle is unloaded.

Separate the upper and lower halves.

Remove the bolt carrier.

Remove the firing pin retaining pin, and withdraw the firing pin from the bolt/carrier assembly.

The firing pin doubles as a punch to remove the trigger group.

With a punch, tap out the hammer pin (it can push out to either side, but one way is easier than the other). A little tap should move the pin groove out from the j-pin inside the hammer, and keep pushing until the pin is entirely out of the receiver. Remove the hammer and its loosely-attached hammer spring.

To remove the trigger may require setting the selector to 'fire' in order to provide some wiggle room - all depends on the trigger and selector combination installed in your rifle

With a punch, push out the trigger pin. It should push out easily, as the legs of the hammer spring engage a small groove on the end of the trigger pin, and that's all that normally retains the trigger pin inside the receiver. Remove the trigger, disconnector and disconnector spring assembly - you can stick the trigger pin back into the assembly to help hold the parts together.

Put all your small parts back together, and put them in a ziploc bag so you don't lose anything.

Re-assembly is the reverse: slide the trigger, disconnector and disconnector assembly into the receiver, slotting the back of the trigger under the selector cam, and making sure by eye that the hole in the trigger will align with the trigger pin holes in the receiver. Slide in the trigger pin, threading it through the half-holes on the sides of the trigger, and wiggling/adjusting to pass through the hole in the disconnector.

place the hammer/hammer spring in the receiver, making sure the legs of the hammer spring are placed on top of the trigger pin. Use one hand to depress the hammer assembly into the receiver, while sliding the hammer pin in from either side of the receiver. There's a groove near the end of one side of the hammer pin, and you whichever side you insert the pin from, you want that groove on the OUTSIDE (so it enters the receiver last). You'll wiggle the hammer assembly into place, and start inserting the hammer pin when you get them lined up. There will be some slight resistance, as the pin has to compress the hammer's j-spring to the side in order to pass through the center of the hammer. Once you've got the pin started through, slide it the rest of the way, adjusting the hammer so the pin can pass through hammer pin hole on the other side of the receiver. Press through until you feel the hammer j-spring engage the groove in the center of the hammer pin - this should roughly coincide with the pin being fully inserted.

Check that the legs of the hammer spring are on top of the trigger pin, and wiggle/adjust the trigger pin to ensure that the legs of the hammer spring engage the groove towards one or the other side of the trigger pin - it's that tension which retains the trigger pin within the receiver.

PS - standard hammer/trigger springs are identical and interchangeable.
