New Trigger from Rise Armament

Rise Armament RA-434Rise Armament RA-434

Rise Armament recently announced the company released its new AR trigger group called the RA-434 High Performance Trigger (HPT).

The new RA-434 HPT is a drop in style, single stage trigger group that is designed to work with most AR platforms based on the 5.56 NATO and .308 Win rounds. So -most- AR-10 and AR-15 rifles should be compatible. If you own an outlier, chances are you already are aware of other compatibility issues. If you have doubts, contact Rise Armament and let them know what you have.

Internal parts are nickel boron coated to reduce friction during the pull. With a 3.5 pound pull weight, Rise Armament describes the pull as “ultra smooth” with a “crisp, clean release.”

The trigger is straight and can be had in either a silver or black finish. Parts are all CNC machined from tool steel and aluminum, and the housing has a black hard coat anodized finish.Rise Armament uses a hammer with relief cuts in this group. The unit has a built in drop safety feature. Overall, the unit weighs 2.4 ounces.

Rise Armament recommends that you use KNS pins to help prevent any walking. The unit has a suggested retail price of $169. If you order the KNS pins at the same time, they will cost you an additional $30 bringing the total to $199. The trigger group is made in the United States.

    For $65 (give or take), BCM’s Nickel-Teflon trigger is awfully hard to beat for its smoothness.

    • Jimmy Chimichanga

      any polished & coated mil spec trigger is going to be smooth…

      you are getting a shorter pull / reset with the drop in, and a 3.5# break.

      I bought the cheapest rise armament drop in for the $99 intro price, and I’m pretty sure it’s a lot better than any standard type trigger group.

      • PK

        Agreed, RISE convinced me to try the trigger for the intro price, as well. I’m impressed.

        • SGT Fish

          ditto. my GF bought me it during the intro price. Its in my primary AR now

          • PK

            I believe it! I only like a few triggers as much as the SA-140 when it was $99… and the smoother/lighter triggers I have generally cost at least twice as much. It was a total steal of a deal when it debuted.

      • Haulin’ Oats

        $65 isn’t an intro price, it’s the MSRP. This is the same great BCM trigger found in the Springfield Saint and theres nothing vanilla-mil-spec standard about that.

        • Bradley

          Those triggers are literally a polished and coated mil spec. It’s still ten times the trigger for about twice the price.

        • Payce

          Mil-Spec is a design standard, doesn’t mean it’s the best. The BCM trigger is just a MS trigger with a coating and a trigger job. Good trigger, I have two, but nothing special.

  • PK

    I don’t see the reason behind buying this over their $99 (intro/when on sale) offering. What are the differences aside from the coating? This, the SA-535, and the SA-140 are 3.5# break single stage triggers. This and the SA-535 have flat triggers, the SA-140 is rounded, but this is more expensive because of which features?

    • Marcus D.

      Because of this and other comments, I looked at reviews of the SA 140 and found one on e-bay for $87 with free shipping. I will give it to my son for his A-10 build. I have an ALG QMS for which I just installed a lighter hammer spring to reduce pull weight, but for such a cheap trigger, it has a very crisp break, no overtravel I can discern and a very short reset. Its only down side (and yes I should have paid the $20 more to get the ACT) has been a very heavy pull.

      • PK

        You’ll probably be amazed how nice the Rise SA-140 is, especially for the price. I found it similar to the “lower end” single stage Geissele triggers, not that any of their products can really be considered low end. I mean that the SA-140 compares favorably to the less expensive models from Geissele, which are still amazing triggers.

    I have the original Rise trigger without the KNS pins. The set screws keep it in place just fine.
