Very well made by Todd, June 16, 2017
Fit perfect in a YHM upper and low profile gas block. I've only put about 50 rounds thru it so far, but initial accuracy with factory ammo has been excellent so far. Can't wait to start running handloads thru it.

It includes all the parts needed to attach it to an upper receiver.

A: The barrel assembly will work with any mil-spec upper receiver. If you have a left hand upper receiver, please make sure to purchase the barrel with an ambi barrel extension to ensure the bolt will properly lock into the barrel extension. Q: Do you provide instructions on how to install the barrel? A: Unfortunately we don't provide directions on how to install a barrel and recommend that it be installed by a gunsmith to prevent damage to the rifle. Q: Do I have to purchase a matched bolt to my barrel? A: With AR-15's as long as you are using the proper bolt for the caliber you do not need to match a bolt to the barrel.image
