My only other slight complaint is that the hole that is supposed to direct the gas away from your face actually allows a little puff of gas to rise up in your face when you are finished shooting. I think it would be better without the hole in the side of the handle. Overall I’m satisfied but since I am new to this, I’m surprised at how expensive a small part can be. Very well made though.On Griffin Armament SNACH Gen 2 AR-15 Charging Handle - BlackJJordon P.Verified Buyer5.0 star rating07/30/25Solid and affordableReview by Jordon P. on 30 Jul 2025 review stating Solid and affordableLightweight, sturdy, couldn’t argue with that price point at all.On Rainier Arms AR-15 Urban Combat M-Lok HandguardRRICHARD B.Verified Buyer3.0 star rating07/30/25Fitment was not great on my gun.Review by RICHARD B. on 30 Jul 2025 review stating Fitment was not great on my gun.The fitment wasn't the greatest the grip did not fit tight to gun even when bolt was completely tightOn A3 Industries Xeno True90 AR-15 Pistol GripDDarren H.Verified Buyer5.0 star rating07/29/25Best looking with exemplary finish lower receiverReview by Darren H. on 29 Jul 2025 review stating Best looking with exemplary finish lower receiverWaiting on a few more parts to complete the build.
