So did I, but I also have lwrc pdw stock and tubes d checked how that matches. Then found KAK industries!aies short tubes as well for just 30+ dollars. Just don't ask how many SL-M stocks I bought, on sale...
In my experience they feel about same. Though sl-s stock I have on another rifle is extremely tight. Let me see how these two feel after I put a few hundred rounds through,as they are part of new SBR upgrades
