View Full Version : Two-stage triggers: Compass Lake or Rock River
March 19, 2002, 06:10 PM
Assuming no difference in price, is there a consensus on which is the best to install?

You aren't being ignored. I was hoping someone with experience with the two would answer this one. I've never seen either so I really can't compare them. Worse I don't know who to tell you to ask. Not much help, huh? George

I don't know about the Compass Lake triggers, but I have two of the RRA 2-stage triggers in my guns, and they drop right in and work great. For around $80, it's hard to beat the value. I'm very happy with the performance of both guns with the new triggers, FWIW. One was the LEGP carbine from AR15.COM, which happens to be a RRA gun, the other was a green label Colt. I like them well enough that I think I'll be putting one in my Carbon-15, the only other AR type rifle I have. :)

Can't help you with the Compass Lake trigger. I've got one Rock River trigger installed in a rifle I'm building right now. It seems like a good, solid trigger so far.
Its a two-stage with about 4.5-5lbs of pull, a very, very crisp break. It was easy to install - although the trigger and hammer pins are slightly oversize and you'll need a mallet to put them in.

I was also curious about the oversize pins, they specifically mention them in the instructions, so they must have some purpose. Do you have any idea why they went that way?

I think it is to keep the pins tight, if there is any play in it the mating surfaces in the parts could be effected. Sloppy wording, sorry. What I am trying to say is that the alignment between trigger, sear and hammer must be consistant or it may cause trouble.

That's a good point, and you may well be right. I was curious that is was obviously by design that they were tight, so that would make sense. :)

I'm not sure why they went that way but I have had the GI-issue pins "walk" out under fire and that creates a really nasty jam when it happens. The slightly oversized pins don't walk at all - it may be that the tighter fit prevents that.

The pins should not walk if everything is assembled correctly (but I will stress the 'should'). The long legs of the hammer spring should be resting in the grooves of the trigger pin. The hammer pin is held by a piece of spring wire in the hammer that catches a groove in the hammer pivot pin. That is why I believe the larger pins are to keep the mating surfaces of trigger parts in proper alignment.
I once went to the range with my issue weapon and had the trigger pin walk out, it was assembled by the armorer wrong, I have made it a point to check it every time I draw a weapon from the armory. I did that before but I did it by the manual, the operators manual does not cover that however.
