Watson's Weapons .50 cal AR conversion?

[AC_Pilot]

Has anyone shot or owned one of these, and what do you think about them? Seems very economical if they are reliable and accurate...

The conversion kit is very well done and accurate. If you want to put a single shot in a target, with massive results, this is it. Get a good scope!

I've got one. HEAVY. accurate. pain to load, but you won't be doing any expen$ive high volume shooting, or losing any brass with that upper. Good glass is a must.
