[where to find core 9mm factory none ported barrel]

i am using that for ipsc so no aftermarket barrel can be used 

[510c mount choice]

my open gun has port very close to the barrel end , and it chips the edge of my signed side blast shield of my rts2 , With both standard size and wide frame size mount , so I got a double tap double side mount for rts2 that sit the dot tight middle of the slide took care of the problem ,  but now 510c gets more popular so kinda want to try , as the deal shop here gave me 2 , just now have to decide what mount I am going to use 

[510c mount choice]

ok I am thinking about tevo and akai , but seems to be akai has narrower base rather than tevo have same size base as the dot

[RTS2 VS VORTEX RAZOR]

i broke 2 razor on my akai open gun under 5000 rounds , both lost battery contact , if i take battery out and bent the leaf spring up , it will work again for another few rounds , had email vortex they said haven't seen that before , my sponsor replaced the dot for me but i end up put rts2 back on just to be safe and haven't hand any issue for about 2000 rounds so far 

[Vortex Razor]

i have used my razor about 1 year on a rht sts mount , never had any problems apart i forgot to change the battery once it died on me
