My favorite upper. Fit and finish are always great and I don't need the forward assist. And Tom's Tactical is where I buy.


The slick slide is actually the original design by Stoner . Think about it ? the assist is a unnecessary item , gets in my way ! Release your bolt unassisted & your cartridge is fed with more power than a assisted plunger will ever do . Let the bolt carrier do what it was built to do ! Cleaning is simpler & doesn’t knock MY arthritic knuckles .. Tom hasn’t given me any extra perks ! Yet , ! But ya never know .. my birthday is soon ! Also the Boron nic . Bolt is super nice . Shipping was quick, packaging was excellent & they are real People! Thanks to Tom & Company !


I like this upper, great fit and finish.


Looks good. My Devil Dog Concepts side charging handle fits on it nicely.


love this upper, will buy again on my next build. Excellent itquality from the manufacturer, and prompt delivery from Toms. I especially like the free shipping.
