Hunter CO, with it pushing 6mm 60 grain pills at 3400ft/sec I think supressing it would be a waste. Evebn with a heavier bullet like the 107 grain they are still traveling at 2450ft/sec.
BTW that is a full non-fluted barrel under the handguards and there is a lead weight in the butt-stock. With scope/rings, bi-pod and a 20 round mag the weight of that rifle comes in at 16.5 lbs.
The Olympic uses a modified 32 round Sten mag, so there is no mag adaptor...or... regular Sten mags with a mag well adaptor. I opted for the 1st option as Sten mags were not very well known for QC and the mag catch hole varies by as much as .200" and there are a lot of folks that can't get them to feed well with the mag well adaptors. If you are into tinkering you can adjust each magazine to make them work though.
I like the 9mm Oly vs. RRA/Colt because you can install the upper on any lower and nothing needs to be changed on the lower. The RRA/Colt will require a hammer, buffer spring and buffer change to make them function reliabily.
Olympic originally designed the pistol caliber uppers and Colt before and after designing their own wanted production right to copy Olympic's design. They were turned down...and hense you know why there are 2 styles of pistol cal uppers on the market today.
Olympic has made and sold 30-50,000 of these, many going to Israel....Colt...less than 5,000, most going to Law Enforcement
A lot of times these folks will give you 10% off you 1st order:
http://www.jsgunparts.com/ $575 - 10%
That would make a complete upper w/ mag $517.50...complete rifle and Oly wants like $900.
www.atlanticfirearms.com had the 2nd best pricing
Maybe I'll finally make it to a shoot and you can try it out. My 5 year old loves it.
Scott....
I haven't attended a shoot yet.
Weekends are tough for me to get off.
