So, I'm still in process of the breakin for this Group Buy - 18" Faxon - but my initial impressions of it are very favorable. Fit and finish are excellent. I've paired it with the monster bolt and things are cycling superbly right out of the box.
At present I have my adjustable GB full open and following breakin I will try to tweak down on the gas but this brings up a couple of questions:
1. When you throttle downward on the gas block do you expect MV to increase? It would seem to be so but I've not been down this road before. My interest here is mainly that it could bump me off of a node (in which case I'll adjust the powder charge)... I guess it could also enable me to reach the next one.
2. This rig will hopefully shoot 90 TNT's, 123sst's and perhaps some 129/130's depending on if I can find a good node for the 129/130s. Is it possible to adjust the gas flow so one is optimum but the others still cycle ok (maybe a little hard but certainly less than if the AGB is full open)? If so which load do you try to set, think it would be preferable to be the 123 but again, never done this.
The first rounds were all factory, 123sst and Hdy Black. The sst's seemed to shoot better but it is still very early on, so no conclusions yet on that.
I like the balance of this upper much more than my current "18", plus it weighs 3-4 oz less, not much but I'll take it.
Wt as configured with scope and no mag: 8 lb 14 oz.
I do believe my current 18 will wind up in the safe. My little family plan is my 16-er (Faxon gunner barrel), howa 20" HB and this one.
