The Rise Armament High Performance Trigger is the first of its kind as a truly premium trigger at mid-range prices. Fixed at a crisp 3.5-pound pull with fast trigger reset and minimal over-travel, this competition ready trigger allows you to shoot more accurately and much faster with much less effort. Trigger reset is how much movement it takes for the trigger to move back into a ready to fire position, so it is extremely important for competition because it allows you to pull the trigger faster than a standard Mil-Spec trigger. Over-travel is how much the trigger continues to move rearward after the trigger breaks and a round is fired; like the reset, minimal movement is optimal for fast follow up shots when every millisecond counts. The straight trigger, disconnector, and lightened hammer have all been precision CNC machined from high-grade heat-treated tool steel with ultra-slick nickel boron coating for smooth contact surfaces and exceptional durability. A lightweight aluminum housing allows for fast and easy drop-in installation while weighing in at just 2.4 oz. The High Performance Trigger is the perfect upgrade for most AR-15 and AR-308 pattern rifles.

NOTE:This trigger has two fitting screws that must be tightened regardless of trigger pin selection. Do not over-tighten or it will change the trigger pull weight. Hammer and trigger pins are not included.

  • 3.5lb. single stage trigger

Inconsistent manufacturing among three RA-434's

by -

Follow-up here to earlier review. Bought two. One was bad. PA sent new trigger (thank you, PA!). Pulls at 3.5 lbs. Was a little tight installing pins. The trigger has a safety stop to prevent discharge if the hammer is released by an impact (dropping weapon) instead of being pulled back. The replacement RA-434, but not my other RA-434, will not fully release the hammer with a second trigger pull when the hammer has been caught by this safety feature (and before re-cocking). The trigger locks up. So both RA-434s work differently. I don't expect this to be a problem because the hammer should not have enough energy starting from the last few degrees of arc to set off the primer. And in either case you have to cycle the weapon by hand anyway to reset the hammer. Range test pending. For the deeply discounted price I paid, I will keep them if they function well at the range.

Two machining errors on 1 of 2 triggers bought.

Bought two. One was perfect- tested at 4 lb pull and installed easily. Great feel and reset- as advertised.
<br>The second one was defective. The rear pin boss (that the receiver pin goes through), is apparently drilled from both sides during production. In this case, the drills were not lined up. One side had an eccentric hole that did not line up with receiver hole (in two lowers). And there was a ridge in the middle that the pin snagged on when going through. Could not install in either of 2 lowers, including a Spike's Tactical. Also, about 1/4 of the hammer face surface was raised above the rest of the face by about 1/2 mm.
<br>I'm keeping the good one and returning the defective one. Quality control is lacking with such inconsistencies.

Needs to be cleaner and oiled b4 install


Like the others said it wasn't 3.5 when I got it and put it in but after I took it out and cleaned and oiled it...it now is consitant at 3.5 on my gauge

Buy something else


This isn’t 3.5 pounds. It’s more like 5. And yes I checked the tension screws. It’s not very crisp. Has creep to it. Has a nice reset but that’s about the only thing positive I can say. I have used: Timney, cmc, geissele, pof, and now this thing. I can say without a doubt this is the worst one of the bunch. I bought it on sale for a good price and figured it might be fun to try something new and I’m regretting it BIG TIME. In my opinion the 65 dollar BCM trigger is better than this one.

This is not a 3.5 lbs trigger. I installed with anti roll pins and performed several test. The only reason I even gave this 3 stars is be cause it is pretty crisp and has a fairly short reset but 3.5lbs it is not. It was consistent between 5 and 5.5 lbs
