Boston Paintball Reflex Kit

Below is a close up of the Boston Paintball reflex kit. I’ve never actually seen one at the field, and only knew of one other collector that owns one (Firepro). Apparently being banned by the NPPL (it can be sweet spotted for full auto) and retailing at almost $500 didn’t help! Video shows some of the key features labeled as it sits mounted on my evolution.
My take: First of all, this thing is crazy. I’ve owned a bunch of autocockers and NONE shoot like this. I read a review saying it is like pushing down hard on your ABS breaks, and I think that is a very accurate analogy. This gun seems to default to full auto, it really should be called an adjustable FA kit. Boston Paintball ended up selling the patent (whose number is engraved on the thick grip frame) to Tippman, who subsequently used it for their successful RT triggers. Interestingly, of all the years I’ve played I’ve never owned a Tippman.
I have to find a beaver tail long enough to cover the cocking rod, which is about a half inch longer than standard (to deal with the longer throw ram).
I’ve fielded this a few times now. The first day the high kick of the marker slipped it out of timing, so I blue lock tight’ed everything. Then I started chopping. So I put a JAM bolt on it. Now I’m dealing with double feeds. So I think the next step will be to put a normal length cocking rod on and see how that does. Complicated kit but interesting… I’d love to keep it running 100% a whole game! (checks notes… never did)
In the early 2020’s, this got re-released, and since then there have been a few limited run versions of these. So they’ve gotten back around.
This was one of the first videos on my youtube channel in ~2005!
And of course if you’re into that kind of stuff, here is a short video of my evolution + reflex kit showing slow and fast full auto, as well as switching it into non reflex mode and back again (youtube).
