For those that have been on the fence because the price was too high, here's your chance to give in to temptation. I have a left side charge on my 300 blk out and love it!

Price is right on both these uppers. If you'er using a scope this is a must have. 

 

My 6mmAR is a side charger.  I like it for the type of rifle it is. I have a mega billet matched set and a Young NM bolt with side charger handle. 

My left-handed Stag match rifle in .223 has a left-side charging handle in addition to the left-side eject port.

The bolt carrier was drilled and tapped by John Scandale of Keystone Accuracy in PA and my upper had the additional milling done by Mike Berezin of MB Sons in Vineland, though Keystone also provides that service.

The modification allows me to cycle the bolt carrier without disturbing my adjustable cheekpiece on the Elisio stock I use
