I have a small quantity of Rock River mid-length complete upper halves with flattop receivers.
These include a charging handle and bolt carrier group with my reliability package.
I can re-configure these into almost anything you want include profiling the barrel, shortening to 14.7" or 14.5" and permanent attaching something etc...
List price on chrome lined chromoly barreled uppers is $495
List price on stainless barreled uppers is $515
No charge to tear-down and rebuild with any other kind of handguards / rail systems / gas blocks or flip-up sights you want to add to the upper.
I have a full selection of options available on my parts page
As the barrels come from Rock River, they are 0.950" under the handguards.
These are heavy profile barrels for sure.
My first special offer is $30 is to re-profile these into medium heavy (0.80") medium weight (0.75"), medium-lightweight (0.70") or government profile (0.65") barrels.
Any barrel that gets re-profiled willl also get re-finished as part of the $30 profiling deal.
Stainless barrels will be finished off with a nice matte finished glass bead blasting.
Chromoly steel barrels will be re-parkerized including under the front sight base.
My second special offer is $30 to shorten and thread to your choice of 14.5" or 14.5"
I have phantoms, vortexes and a wide variety of muzzle brakes that can be permanent attached for those in ban states.
$20 for a permanent attached A2 flash suppressor
$50 for a permanent attached Phantom (all 3 styles are in stock)
$80 for a permanent attached Vortex
Chrome-lined barrels have a 5.56 chamber and 1:9" twist rate.
Stainless barrels have a 223 Wylde chamber and 1:8" twist rate.
Other upgrades that I do will include my standard reliability upgrades:
O-ring added to the extractor
Gas key properly staked with a MOACKS
Gas tube alignment checked and straightened if necessary.
Carrier checked for proper movement within the receiver.
