I recently purchased a Tac-Sol trail-lite barrel with the intention of buying a buckmark to put it on.  After looking at the buckmarks, my new question is which one should I get?  I purchased the 4" threaded barrel, and have a spectre II I intent to use with it (along with a RDS and an IR laser for fun under NODS).  I've looked at all the different buckmarks, but can't figure out what any one offers over the others if I'm going to put a new barrel on it.  Any recommendations on which to get?  I was previously leaning towards the camper URX, but that was simply because it was the cheapest version I could find.

I would go with a basic Camper model, cheapest one you can find.

Should give you the most aftermarket options down the road, sounds like you want to tinker with it anyway.

honestly I would have just gotten the Supressor ready Field Target...its a great pistol.
