Works perfect printed a little overkill with Siriya tech ppa-cf on a Bambu lab H2D at 320 degrees nozzle 110degree bed .12mm fine detail 10 wall loops with infill embedded into wall and 99% rectilinear infill. Annealed in Sunlu E2 at 110c for 12 hours.

Could easily be printed in pa6cf and would work fine.

Safety is smoother than factory. As far as the actuator this is with the -1 but zero works fine also.

Can be removed in 10 seconds and the safety works fine with no frt or trip installed just shoots semi as intended.

Just some video I shot today of Stevo's FRT and the Kuna at the range. I am rapidly approaching 1700 rounds on this FRT. The Kuna gets shot... alot at the range as you can see from the video everyone wants to play with it lol. The FRT is showing no signs of wear, the trip also no signs and most importantly the Kuna is showing no signs of wear. The FRT is much easier to remove than what you see in the video its just hard to hold the kuna balance a camera and pop out the FRT especially when your very left handed and trying to do something that requires a small amount of dexterity with your right hand lol. This is a bone stock Kuna with a factory oem stock that has been form1'd. I do have the HBI spring (not the buffer) but that was removed for this video (it's ROF is faster with the HBI spring).

Bottom line it can be removed in less than 15 seconds and its back to semi it works perfectly, if its not working you may be squeezing the trigger too hard or you may need to slightly adjust the actuator by printing a + or - one. There is absolutely zero reason to fab this out of metal. This was printed out of about $.50 worth of PA6CF zero reason to buy a new lower to just mag dump, zero reason to mail off your lower so someone can monkey with it. Print the file its found on the usual places which no on reddit can say due to regulations so dont ask but it takes minimal effort to find. If you dont have a printer make a friend out of someone who has one in the end that will be worth more than the frt.

Stevo you are truly the man!

It’s working. And yes that is a booster less Huxwrx Flow…

I have about 440 rounds into the FRT so far but more work to do 😎

Stevo is a legend.
