I sold my duty rifle and am looking to order a Rock River tactical rifle...I'm seeking anyone with experience who could offer suggestions on which model might be best. It will be for use in the patrol division. My plan on this one would be to go with the standard sights, and possibly a laser sighting device, but I have no experience with them, having had an Aimpoint on my last rifle. Many thanks....

get with adco firearms, he offers lots of rra products

I would check either the Tactical Entry, the CAR A4, or the Elite CAR A4 which has the mid-length gas system and handguards. I bought the CAR A4.  Only difference between Tactical Entry and CAR is the grenade launcher notch in barrel.  For civilian and police use its strictly cosmetic.  Many people like it because it has more of an original "M4" look.  I believe these are the only two in 5.56 that I would recommend for patrol use.  I wish I would have bought the mid length because it's gas system is suppose to be, in theory,  a little more reliable and less stress on weapon.  Many report a lighter recoil.  The mid length is also good for  people who like to grab the handguard a little close to the muzzle .  I bought mine from Eaglefirearms.NET and found them to have to best internet prices and great customer service.  Good luck. Oh yeah, if you want chrome lined barrel you have to specify it  with RRA weapons.

You might want to check out the RRA DEA rifle (or do they call it the Government model?) specs and then build one up from parts or a kit.  Seems to cover a lot of the bases.  I built kind of an upgraded version of it with a GTS 16" midlength Recon barrel; turned out nice.  
eta; the EOTech 552 might be a nice optic for your work; I like mine.

I have a RRA Carbine with UTE upper and I love it.  It has the mid-length handguards,  the sight radius is a bit longer than the carbine with the shorter M4 handguards and the overall rifle length is the same.  I installed an Aimpoint ML2 and the sights will co-witness with the red dot on the Aimpoint.  There is a screw on cap on the right side of the upper receiver, which encloses a storage area for a spare Aimpoint battery.  I added a GG&G flashlight mount to the upper handguard, which will hold the M3 light I use on my Glock 22.  I installed a Giles Wilderness sling and it makes it easy to transition from the rifle to the pistol.  

If I were you I would purchase a lower then shop around for an upper.  Pete at Legal Transfers can fix you up or you can go to ADCO which has a good reputation in the firearms community.  There are websites for both vendors and they are very accommodating.

i would also suggest one of the models with the 16 inch barrel and mid-length gas system.  i have about 1200 rounds through my rra mid-length and havent had a single problem.  it is a great product

Since it is to be a duty rifle, check to see if you can use the 14.5" barreled version

If so, do.

It will be more maneuverable, and easier to wield from a squad car.

While the RRA products are some of the best, I wouldn't rule out Bushmaster Patrolman's Carbine (A3 version), or the LE Series of Colt AR15's - like the LE 6920, 6921 (the 14.5" model and semi version of the venerable M4, or 6721 tactical Carbine.

The latter will run about $100 more for LEO's, and in my opinion worth many times that


But all are worthy of protecting one's life.

Good luck and keep us posted on your choice.
