i was looking for a ar scope mount. thought about the burris pepr but i hear the larue tactical lt104 is one of the best i may have the model number wrong. im going to use it with a 1 inch tube on my new 6x45 i just got my new upper reciever from frontier arms yesterday. these upper recievers with the black hole weaponry barrel are pretty cool looking. will let you how it shoots as soon as i get my trigger and hammer assembly back from bill springfield. working on getting a scope and a ar mount to finish this build.
