Feedback, user experience on 20 in. with A5 stock
I've had a spare LRB lower sitting in my safe for 6 years now that I built with a G&R Tactical parts kit (yeah it was that long ago), and aside from hosting a 14.5 in. M4 clone for a short time, it's been unused. I tossed around the idea of building a lightweight 16 in. middy GP whatever build with a fancy 12-14 inch rail and blah blah blah. I already have a 10.5 MK18-type SBR for home defense, and I'm not fighting out of a vehicle or anything like that.
Recently I have been fascinated by the thoughts of an M16A5 type rifle. Like many on the forum, I started my military career on the M16A2 rifle and have always had an affinity for how the 20 in. rifles run. The sight radius is killer, the recoil is almost nothing, and the 5.56 ballistics out of a 20 in. barrel is impressive. I've made some great shots with M16s and aside from the ridiculous length stock, I like the form factor a lot. For a range toy, possible carbine classes, and amateur 3-gun stuff, I think it might be pretty cool. I'm thinking of a 20 in. flattop with a fixed FSB, KAC M5 rail, Vickers sling, and a Vltor A5 EMOD stock. I have a KAC 600 meter micro sight which I would be using for the time being, possibly adding an optic later.
What are people's thoughts and experiences with the M16A5(ish) rifles?
