Well I bought a rra 2 stage trigger and now I am getting anxious about tackling the installation. I need a pep talk and ..pointers from those of you that have installed this in a Bushmaster. Any tips would be appreciated. I am an avid DYI guy and and all around handy man at home, but have not done rifle takedown to point of removal of stock trigger, etc...


So what's the scoop is this an easy 10 minute drop in??

It's quite simple, especially if you've stripped your trigger group down to all the small parts before. Refer to the [url=http://www.ar15.com/content/docs/assembly/lower/]lower receiver assembly instructions[/url] if you aren't familiar with all the trigger group parts. Essentially, all you have to do is remove your upper, hold the hammer back with your thumb to keep the tension on it, and drift out the hammer and trigger pins with a punch. Then you just pull the old hammer, trigger, and disconnector out, and replace them with the new trigger and hammer. The hardest part is keeping the hammer spring under pressure while tapping the pin back into place.

... Thanks Terrato , I will read thru the info you suggested, that along with the RRA instructions should help me become familiar with parts and process. I plan on doing this trigger install as next rainy day project.

YEs, it's a 10 minute job just pay attention to where the legs of the springs go

Pins might be a little tight going in. This seems to be normal. Other than that, just follow Terrato's post. Piece of cake!

It'll be much easier to install if you have an extra trigger pin that you can shorten to the the same width as the trigger assembly and use it as a slave pin. A piece of drill rod of the same diameter will work also. Pre-assemble the trigger assembly, slip it in and drive out the slave pin with the stock trigger pin. Make sure the trigger pin is oriented the same direction as it came out.

Just completed the successful trigger installation. Got to admit it took longer then 10 minutes!!! actually took 6 hrs. took 20 minutes to take down rifle, dismantle oem trigger, install new 2 stage trigger,,,, then I went to a party for 5 hours and got 1/2 smashed,,, sobered up and installed the hammer. trick is to use the slave pin idea and it is much easier to install. keeping the hammer under tension and driving the new pins is touch to do . I used the old pins as slave pin and tapped in new over size pins which come with rra 2 stage trigger set. thanks to all for the feedback on how to install.
