Guys, first off I have +55 feedback. So please deal with confidence.[;)]

Like new Lightweight 16" upper from Ko-tonics (aka Cardinal Armory).

Upper comes complete with CMT/STAG 6.8SPC bolt, carrier and charging handle, YHM free-floated mid-length rail, YHM Gas-block mounted front flip sight and (1) 25rd magazine and (1) 5rd magazine.

Fired exact 59 rounds of new Hornady TAP ammunition through the upper. The bolt and carrier was used in another 6.8 upper and has close to 200 rds on it...there is very minor wear.

-This is the latest of Tim's uppers with the SPC II chamber, Chrome-lined 1:11 twist, M4 feedramps
-Purchased brand new from Tim @ Ko-tonics on 5/19/2008 (less then 2 months ago) You can call and verify with him if you would like as well.[8D]

This was built by Tim, the YHM free-float rail was installed by Ko-tonics.

Information borrowed from Tim's website:
-Stag Arms M4 upper receiver with M4 feedramps
-Improved SAAMI-spec chamber to handle the hottest 6.8mm SPC loads
-Four groove button rifling, 1:11" rate of twist, for higher velocity and great accuracy
-All barrels are 4140 chromoly with chrome-lined chamber and bore for easy cleaning and long-life.
-Mid-length gas port for lower cycle pressure and increased reliability
-M4-type feed ramp cut in the barrel extension and receiver for smooth feeding
-5/8-24 threaded muzzle, the standard thread size for 6.8 and .308 muzzle devices
-one-piece YHM free-float forend

I paid the following:
-$566. for the upper
-$75.40 for the YHM gas block
-$17.50 for the 25 rd magazine
-$17.50 for the 5 rd magazine
-$130 for the CMT/STAG bolt/bolt carrier and charging handle.
-$25 for the A2 type flash hider

I have over $830 + tax invested in this upper

I will take $700 FTF or $715 shipped via USPS Priority mail with delivery confirmation
I accept paypal (+3.5) or USPS Money order.
Only trade I am intersted in would be an LMT 10.5" upper.
