I've ended up with some AR's and lots of parts and equipment, much of which I did not expect. I had a M4-gery damaged by a gunsmith (most of ya'll are hip to that scenario, so I won't wast space with details) to the point that it could be turned into anything from here on out. Since the role of that rifle is up in the air and I was gifted another rifle in the mean time, I have several possibilities for finished product(s) I'm asking for help finding identities for these rifles. Thanks in Advance!!! Here is what I'm working with: RIFLE #1: Bushmaster Dissipator 16" barrel, rifle length hand guards, carbine length gas system. Everything is bone stock, except some rails added to the stock hand-guards for accessories. I'm thinking leave it as a short range (0-200 yds) house gun, short range, first line of defense, maybe red-dot (the A2 irons rock on this one so night sights, which I'm looking at might just be as far as I go) laser/light combo, etc. SEE PIC #1 OK that was easy, NOW here's where I'm getting stuck. RIFLE #2: My first build was damn good. It was a BCM upper on a Spike's lower that came back damaged, it still has a good upper and lower and internal parts and is (was) decked out with accessories. The 14.5" barrel is questionable from the weld, but appears to be at the OK mark. OPTION #1I could re-barrel it to something in the 18"-20", change the stock to one with a better cheek weld, mount a scope, probably my Nikon Monarch 2.5-10 x 42mm (w/ quick release mounts of course) on it and make this my tack driving mid range AR? I'd leave all accessories and components that are on it, just change the barrel mainly and scope it. All this would cost would be the barrel. I've thoroughly tested this gun and it functions flawlessly with ANY brand, type or case, weight, etc. You name the ammo out there, IT SHOOTS IT! OPTION #2 Try again to have the thing worked on by a reputable (found one! ) gunsmith as it sits on 14.5" barrel and keep it as an M4 set up. With the barrel it has in it, the rifle grouped very well for a shorty ('bout 2.5" + or - 1" on a lead sled) and since it is a mid-length gas system it functions optimally in the 14.5"-18" range. It would take a red dot, light/laser combo, angled fore-grip, etc. (SEE 2nd PIC) RIFLE #3:- new upper Several Lowers! When AIM surplus had sales I bought 2 Spike's, which were above average for a forged lower as I used on my build. Also 2 "Surplus Arms Ammo". These were not quite as great as Spike's, but MORE THAN acceptable, but definitely WAY better than DPMS and just as good as a Del-ton, Double Star, etc. OPTION #1: SO I was putting an upper together in this order on a Daniel Defense A4 type upper, BCG and free float quad rail. I would barrel this depending on what I do with the BCM M-4 build that is in need of repair. If I leave that rifle (M4 set up) BCM upper in the M4 set up and save the barrel, I would put a 20" barrel on this upper and use the Nikon 2.5 -10 x 42mm until I can find a good Redfield, Nikon and completely devote this to precision. OPTION #2: As I was browsing around for parts I came across a killer deal at AIM for a Spike's upper, which is what the lower to this rifle would be. $499 for complete upper and their BCG included. Then I would have 2 mid-length gas M4 types. I would obviously set them up differently and I LOVE the set up. This would also cost about $200-$300 LESS than the above option. That's a piece of glass men. I'd like to hear about and see some of the AR guys rifle set ups and the reason you got 'em and what type of use they get. For Example: This is my Bushmaster 24" Varminter, it has a 6-18 x 50mm Scope and a Yankee Hill float tube supported by a Harris bi-pod. I would appreciate the help and love to hear my fellow respected member's opinions. It took me a long time to write the above, I hope it wasn't for not! Thanks!
