Update... Recieved my Risr from Larue but the spring is either out of spec or cut to short. Larue Tactical has sent me out another Risr and from what I can tell another CTR stock as well.
I will be suprised and extremely impressed with them if they did.
YHM has made me send back the misdrilled Gas block and will be sending me another one by the weekend with reimbusement for shipping.
Picked up some new milspec 123F ammo and loaded my mags with it.
only things left to do are find some loaner tools to get everything tightened up once I get my new gas block
The Risr is a reciprocating riser that doesnt interfer with charging handle use. When you charge the AR the Risr slides back and when you release the charging handle the Risr travels forward to its original position.
