*Solved* Help needed with Hi-Capa Infinity SV Custom Tumb Safety and Beavertail Grip install problems.

Hi Guys,

I am trying to build an airsoft pistol which all the parts from the same brand and supplier.The last couple months i bought the following parts online at Prog4 :

- AR2104 Conversion kit for Marui 5.1 SV
- AR1498 Disconnector for Marui Hi-Capa
- AR1992---Thumb safety for Marui :
- AR1991---Grip safety for Marui :
- AR1812---Hammer for Marui Hi-Capa

own spare parts :

- orginal UAC Sear Spring Hi Capa
- Tokyo Marui Grip Safety Sping parts

When i try to assemble the AR2104 Conversion kit middle receiver using
a orginal Tokyo Marui Grip and all the parts mentioned above, i having
trouble installing the Grip safety and Thumb safety.

The hammer is fully cocked back and when i insert the AR1992---Thumb
safety in safe modus it fits fine, but i can't turn the
Thumb safety down to semi shoot modus. It seems to block, but i can find
the cause and the AR1991---Grip safety has no tension. I tried another
sear where the left sear is more up. This one gives more grip but the
problem with the Thumb safety stays the same.

Does anyone has experienced the same situation and how did you solve it ? Unfortunately, i don't know any local (airsoft) gunsmith and i hope that i can solve it and learn about it from the experienced forum members

Thanks for any help !
