JSE SURPLUS Rhinohide upper

[JohnnyK]

I'm looking for custom AR upper and they have these in stock... how is Rhinohide different than stock AR upper? I know it's ceramic coating... but anybody here have any of these or opinion of them?

also, what is the difference in their bolt carriers? what is m-16 bolt carrier and how is it different than Rock River Arms carrier? is it worth the price upgrade?

also anyone know what the difference between the DPMS Miculek compensator $37 is different from the $10 Guntec Miculek compensator?

actually they have 1x 9 Nitride uppers.... which is better? 1x7 or 1x9? Rhinohide or Nitride? I plan on using 55 or 62 grain bullets mainly for target shooting and 3-gun... thanks, Johnny

I can only speak to the twist rate but either the 1:7 or the 1:9 will work great for your stated bullet weights. If you want to start messing around with the 70+gr bullets then the 1:7 would be a better choice. I have a 1:7 barrel and it shoots 55gr just fine.

I also plan on getting .22 conversion is 1 x 9 still the better choice?

Honestly I have never seen a 22 conversion that was really all that good. I'd opt for a dedicated 22 upper instead. Tactical Solutions makes some nice stuff and is not too expensive. Though more than a conversion.
