finally picked up my Hybrid, I was waiting for my P239 Tactical shipped separately to arrive so I could do one 4473 for both but looks like it was stolen while in the care of the USPS. I guess the govt. does need better gun control.
anyway, I purchased the Hybrid 5.56 pistol with 11.5" barrel. I can post pics upon request. I also purchased a Virtus 6.75" 300 BO barrel kit which came with the updated Virtus bolt.
Some observations before I take it to the range.
I was hoping to get the updated Virtus charging handle based on some examples I had seen on gunbroker, however I got the original generation handle. I went back to gunbroker and looked at the minority of auctions that didn't use canned pics. It seems that the updated Virtus charging handle appears on .300 BO pistols and rifles. I didn't see any examples on 5.56 guns but its a small sample. Mine was mfg. in Dec 2017 if that makes any difference.
Handguard is too small for a suppressor so it won't work with my 300 BO barrel kit. Not a big fan of how the keylok handguard looked anyway, looks like some cheap China made handguard. However, the handguard for the 9" 300 BO pistol looks a little nicer with at least a QD mount near the receiver. Will look into MI handguards.
BTW, I would have possibly bought the 9" 300 BO pistol version as it was cheaper, however the twist rate is 1/5 which is supposedly causing issues with suppressors when used with supersonic ammo. If a 300 BO rifle is not suited for use with supersonic, might as well go shorter if subsonic only.
I plan to remove the parts and put it on an SBR lower I have. I was planning to use my Colt lower, however I notice the styling of the upper is a better match for my Quentin Defense Billet Lower that is also SBRd so unsure which one I will use. The arm brace appears to use a buffer tube folder plus a regular AR15 sig arm brace. I will remove the arm brace portion and use the folder mechanism with a regular AR 15 buffer tube and a stock. I will take the left over arm brace and install it on the original Sig lower.
On a side note, the MCX Hybrid as sold has a LOP of 14.25". So go figure, I thought that was an uncountable number and thou shall stop at 12.5"...
