Hi everyone, 

Just picked up a Troy A4 “other firearm” and was interested in RDS. Looking for recommendations from 

forum members. 

Thanks, 

Vortex Crossfire / SPARC or something similarly sized.

Congrats on your purchase.  I have shot one and really liked it. Recommend you check out the Sig Sauer  Romeo 5.

Thank you guys. Appreciate it. 

Trijicon MRO.

Congrats on the purchase. I have a Holosun 510C on my "other firearm" as I prefer more than just a small dot. I have Astigmatism issues, so I find that prism sights work best. I have a Primary Arms GLX 2X prism scope on order. 

I got this Holosun when it was on sale. I've only shot my "other" with it once but I was extremely happy with it.

I put the holosun 510c on mine. I really like it

Nice photography!

That sight looks a little low - you may want to get a riser for it.

I first used my Holosun HS507C on mine but it was too low to get a good sight picture or cheek weld.

I switched to a Vortex Crossfire and it's at a proper height now.  Much easier to bring on target.

Yea I discovered that 1st time at the range. Luckily Holosun makes a small riser plate that brings it up to lower 1/3 witness height. I just didn’t take a pic of it
