Budget RDO recommendations for keltec RDB

[J10on4ds]

Hello fellow INGO members.
Made a recent purchase and could use some advice.
For those that don’t know... The RDB uses a charging handle on the left side. Need to make sure nothing sticks out too much over there.

Any red dot recommendations?
I have a primary arms on my sub 2k that hasn’t ever given me any trouble.

Bushnell TRS-25, Sig Romeo 5 (I think that's the cheap one), Primary Arms Micro Dot. Take your pick.

Thanks Tactically Fat! I’ll look into those other two.
Im so glad I asked on here I’d forgotten all about the Romeo5. Purely from the torture tests online that ones in the lead.

So after doing some research...
I ended up going with the Romeo 5. Should be here in a day or so. I’ll try and get some pics up.

I think this will work...
just need to find time to dial it in!!!

My son put a Sig Romeo 5 of some sort (the one that takes the AAA battery) and it works great. We found his RDB is the perfect suppressor host too on our last range therapy day. I built a primitive freeze plug Form 1 300 blackout suppressor many years ago, then recently sold the gun. One little 5/8-24 to 1/2-28 adapter and we tried it on his RDB. It actually makes the sucker hearing safe (shocked I was) and the adjustable gas block let him tune it perfectly. Cannot sell the sucker to him without the $200 transfer but I can loan it to him indefinitely then add him to the trust when I have time and money to revise it.
