Last week I received a Mark II FV-SR as a gift from a friend to celebrate the birth of my second child. My impressions so far:
Positive:
GREAT trigger out of the box. Really impressed.
Heavy barrel should tolerate heat well and be reasonably accurate.
Overall a nice lightweight, compact package.
Negative:
Stock is definitely going to need a cheek riser. Seems like even just looking down the scope rail I can only get a chin weld. I like the look of the DIY kydex kit off eBay that was posted earlier.
Threads on the muzzle are too long for my SilencerCo Sparrow to seat properly against the shoulder. I put a timing washer on there for now. Worth paying ~$40 for a SiCo 1/2-28 to 1/2-28 w/ o-ring clearance adapter?
Mag release is counter-intuitive and feels pretty cheap. But then I'm probably not going to be doing emergency reloads on timed coursed of fire with it.
Since this is really for my kids when they are old enough to learn to shoot, I doubt it will be used much beyond 25 yards (deepest action bays at my local club). Is the Primary Arms 1-4x the best cheap low power variable around these days? Or would even that be overkill? I already have an M&P 15-22 with a red dot for when they're up for a semi-auto, but I'd like this to be a handy, short-range precision setup.
The only spare optic I have lying around is CompM4, which might be a bit large for it.
