View Full Version : VS3 valve, spring, hammer and bolt in an MR1....

I was doing a tear down and cleaning of a vs3 I just got and started to notice the similarities of the receiver to the MR1. Well, for the hell of it, I installed the VS3 valve, spring, shorty hammer and delrin bolt into my MR1. The bolt needs a modding for a detent grove but other than that it works. The valve on the other hand worked only to about 80% of it's potential as it did not re-cock. I am assuming it is as simple as adding the 3 small relief holes and plugging up the one bigger original hole on the bottom of the receiver? Can anyone verify this or has even done this? I want to be sure before I actually go ahead and look & get xtra vs2/3 parts to actually go thru with this MR1 LP mod.
