AR180B help - can't figure out how to remove the trigger... ?

[Flumser]

I feel like I'm overlooking something super obvious here... But I cannot for the life of me figure out how to remove the trigger from my AR180B. My plan is to replace it with an AR trigger that I like better, and from everything I read it's interchangeable except for the pins.

In the photos you can see my issue: the bolt catch piece extends from the rear of the magwell all the way along the inside of the reciever, effectively making the width of the inside of the reciever skinnier by a few millimeters. The hammer and trigger lie underneath it, so this thin piece of metal makes the reciever too skinny to pull out the hammer. I hope you can understand what I mean by looking at the pictures.

All I want to do is take out the trigger and put a new one in. Is there some trick to this? I've replaced AR15 triggers numerous times before without issue.
Is there some way to remove the bolt catch? It's under extremely tight spring tension so I didn't want to mess with it.

Thanks in advance for any help.

This may help you. Start at 1:30.

If the bolt hold open is in the way, remove it. It's held in by an E-clip on the pin it pivots on. Bolt hold open is far from being under "extremely tight spring pressure". It's actually rather weak.

It's not rocket surgery, buddy.

Thanks for the video, I didn't realize that clip was removable. And I meant the spring that holds the safety and bolt hold open lever is extremely tight, not the e clip. I'm very new to the 180B (if you couldn't tell).

No, the spring is not tight. It's just a small spring that holds the bolt hold open down.

You'll also have to remove the selector before the trigger will come out.

Alright well regardless of spring tension, the trigger is in! I just followed the steps in the video, so I didn't remove the safety selector but everything seems to have worked out. Thanks again for the help.

What trigger did you put in? I've never changed any of mine.

 

[Flumser]

It's an ALG QMS - a big improvement for the money. Not super light (6.5lb pull) but it's nice and crisp with no grittiness.

I really wish someone would make those lowers available.

NEA would be our best bet. If anyone in Canada could do it, it probaly would be them. They were hinting that they might make some AR180B2 a few years back. Obviously nothing so far has come of that.

They have something in works, not sure on a time frame. I sold them my drawings.

Just a bit off topic. You may want to just check and tighten the 2 screws holding the front sight post. Mine slowly got loose and allowed the post to move a bit enough to partially block the gas port. Not enough gas to actuate the operating rod.

I wouldn't mind owning one of those AR180b
