There is a table, way back in this tread, but it is extremely dependent on many conditions so your results will likely be different. Temperature plays a huge factor, and can move your FPS all over the board. Then there is the condition of your air seal, that can change your results pretty dramatically. If you knew one FPS result, at one temperature, with the cradle VA installed, it would go a long way in determining your expected results. Sent from my DROID RAZR using Tapatalk 2

So you're from Michigan. Are you on MiA? By the way, I placed my Cradle order on last Friday, I believe, and I just got an email saying it shipped out today.

6-32 thread size. The length wasn't really specified, I don't think. I use 3/4" long set screws. With that length, the set screw is just about flush with the top of the receiver, when the hop up is turned completely off. I had a hell of a time trying to find that size available at any local store around me, so I ordered it from McMaster Carr. There were two types I tried. The first, part number 92313A154, is just a plain stainless steel set screw. The second one I ordered is part number 91385A911. That second one has a small nub of nylon sticking out the side of the screw for purposes

Hello fellow KJW owners, I purchased my first KJW M4 just a few days ago. After reading through all 282 pages of this forum, I've determined it to be a V1.1, due to the piston and the fact that it appears to push on the buffer when I'm closing the receiver halves, without a cradle bolt extension installed. It also does not have a weight installed on the bolt. The previous owner installed a Cradle Velocity Adjuster but did not include any spacers, so I'll be ordering a set in the next few days, along with a V1+ bolt. I like the idea of a quick change out for velocity adjustment. I'm

If your referring to your upper and lower receiver not fitting tightly, like I think you are trying to say, this is not uncommon after a while of use. I know you said you bought this from Redwolf, but is it a used gun? I would think it would take longer than just one game for it to loosen up. I recently purchased a V1.1 from someone on my home forum, and mine has a slight "wobble" too. I don't notice it much since it is identical to my real AR. ARs aren't super tight. You probably would have gotten away with opening the mag up, cleaning the valve and o ring, packing it with some sil
