So my order arrived today from Red X Arms. So far, things are looking pretty good. It took 6 business days to ship. Their website lists all over the place that in-stock parts will ship in 5-10 business days, so this seems about right. I figure it is better they are honest up front rather than take my order without telling me.
Anyhow is the whole order:
I ordered BCG, free float tube, A2 stock, and LPK.
The free float tube looks pretty good. The knurling is coarse, but I kind of like it that way.
BCG is staked. Looks ok to me.
What I really like so far is the pistol grip that came with the lower parts kit. I ordered the kit with their "combat grip". The grip is hard plastic and the finger grooves fit my hand well.
I'm still waiting on the gas block to come from another source before I finish the build and shoot it. That will be the true test.
