im looking into getting one, is there anything i need to know: flaws, pros, cons, alternitives, ect...............
thanks in advance
I'm glad to help. I'm a full time gunsmith that specializes in AK's, so I have much experience installing all kinds of AK Triggers, especially the RSA triggers.
There are 4 popular trigger systems:
Tapco (Nice but not great unless polished properly, better with a 25% reduced spring kit. Tapcos have a light, but LOOOOONG pull)
K-Var/Arsenal (Crap, dont even consider them. They break and have VERY ROUGH surfaces)
RSA (Easiest Adjustable system to Install, Light pull, Strong materials, Reliable if installed properly, short pull)
Jard (lightest of all but most need LOTS of stoning to not cause the action to hang up, I don't recomend them)
I recomend getting the RSA trigger or Tapco, AND a RSA retainer plate as well. You'll know how valuable these are if you try to reuse the factory wire pin retainer (shepherds crook)
If you decide on the RSA:
My recommendations are where RSA has stoned take some jewelers rouge and a felt disk on a dremel and polish the parts they stoned. Don't round anything just polish where the parts are stoned.
Second tip is to completely disassemble the trigger kit, and take out all of the adjustment screws (Remember where they go). You want to degrease all of the parts and adjustment screws with acetone, gun scrubber or brake cleaner.
Third tip is to use red loctite on the adjustment screws. Don't use the green sleeve retaining liquid they supply. The red is stronger.
Fourth Tip is do not oil or grease anything until 3 days after you have adjusted the trigger. You want to give the loctite time to setup. You want to adjust the trigger for minimal creep, takeup, and overtravel. You want to have a little hammer/sear engagement as allowable so there is no creep. The instructions included with the trigger do a great job of explaining how to adjust things.
Last, the safety shouldn't be fit until you have a chance to test fire the weapon. If you fit the safety to the trigger kit and have hammer follow or need to make adjustments to the set screws your safety engagement will be sloppy and wont hold. Run 100 rounds thru the gun before fitting the safety. When fitting the safety the instructions tell you to cut the engagement tab. Do this slow with a file. removing too much requires you to weld re-weld the tab or replace the safety.
If you have any questions once getting the kit feel free to message me and Ill be glad to help further.
Take Care.
