Yes I know this isn't the Rimfire page but I just wanted to draw a consensus from the general forum experts on which drop in .22lr conversion kit is BETTER.  CMMG or Spike Tactical?  Please give me some opinions.  Like everything I've read on CMMG in terms of performance but I can't help but like the nickel finish on the spike bolt

I think CMMG has a Chrome kit also

They have a stainless one available at CDNN  http://www.cdnninvestments.com/ar22stcokitw.html
I have Spikes and the CMMG stainless.




I had to tune my Spikes kit just a little.



ETA Spikes has always been top notch answering my questions about anything both on the board and via IM....




Both run ~ 100%  with federal bulk pack that's to say i have several thousand rnds threw each with that ammo with no malfunctions.
Sometimes various other ammo occasionally creates a ftej or a light strike.
