So you really only have a handful of choices if you want a 556 pistol without a buffer tube-- The PLR16, An Extar556 or a PAP92/85. I disqualified the Pap for weight and sheer cost of mods to get it to where I wanted. If it were just a contest between the PLR and Extar Mk1, it'd be a tossup, but I found a local dealer with Mk2 in stock. At that point I get a full length top rail standard, stock picatinny mount, a (mostly) standard AR lower and hand guard standard. Got the reddot sighted in, but I'm still within the 200 round break-in cycle. It does not like IMI 55gr, but everything else seems to run without issues. Trinkets for the pistol are still trickling in, including a single point sling (I didn't buy it just to put a stock on it, frankly). Theoretically I could purchase their Extar tri-rail picatinny kit for the hand guard, but I just can't bring $50 for what are effectively rails with notches. It has enough top rail space for a couple of 45 degree offsets, and those only cost $7 for two. The Rhino magwell funnel grip is already installed. Could have gone with a Mako product there, but uhg, it makes your setup look like airsoft. The Rhino is a nice product, btw. Fire is very controllable due to the aggressive muzzle break. It gives firing the pistol a rolling motion as opposed to a snap. It also causes the pistol to boom like a cannon, but I'm fine with that. About the only drawback I can point to so far is that the break isn't supposed to be user serviceable. I can live with this tradeoff. Going to the range is somewhat annoying in that everybody assumes it has no other use than to make noise and fireballs, but it is what it is. Seems like a fine product so far. I have almost all the parts so I'll update this thread later if there's interest.
