Lightly used varmint type AR-15 upper receiver group. It has exactly 343 round down the barrel, all slow fired from a bench. 

Here's the breakdown:

- Shilen 20" HBAR, non threaded muzzle, stainless barrel with 1/8 twist and a 223 Wylde chamber. Barrel came with a matched bolt from Shilen

- Slick side 7075 forged receiver

- Superlative Arms DI bolt carrier 

- KAK 15" handguard with steel barrel nut

- Sadlak .750" gas block and gas tube

- Mapgpul polymer ejection port cover

- Mil Spec charging handle with YHM extended latch

The barrel has been epoxy bedded to the upper receiver for increased accuracy. This upper shoots tight groups with little effort.

I have included a few pictures of a few 100 yard groups from my last outing. Ammo used was some of my generic hand loads using once fired PMC brass, Ginex SRP, 24.5 grains of Varget, and Rocky Mountain Reloading 69gr BTHP projectiles.

Only the upper is for sale or trade. The lower, scope, etc. are not included but I am willing to part out the lower if there is any interest.

Interested in trading for AR parts and/or 5.56/300 Blk ammo.
