Posted this over at the "Competition & Accurate Forum" w/ no response?!? Thought I'd give it a shot here.

I'm thinking about putting together an A3 type carbine for 3-gun, defensive, & field work. A little input would be appreciated!

Basic platform: Rock River, BM Flat top, or other?

Optics: EOHolo, CMore, or other?

Backup sights: A3 (removable handle), A4 modular folding, none?

Barrel: chromemoly - lined / unlined, or SS? HBAR, M4, Heavy?

Brake: Y/N? If yes - which one?

Free float tube - worth it? If yes - which one? I'm looking at the BM modular. Like the idea of being able to attach a side mount sling.

Trigger group: JP single adj, Jewell, or RR 2 stage?

Well guys, what about it? Thanks in advance!

At our local three gun matches you sometimes have to engage paper and steel at 200+ yards. magnified optics is a big plus. I currently use a 2x20 mini ACOG. In the past I had an Elcan that worked well. I've been thinking of setting up another rifle with a Leupold Vari-X III 1.5-5x20mm Illuminated Circle Dot Reticle scope in ARMS rings.

Interesting points - both. Appreciate the input. Thinking about the EOTech Holo, but they don't seem to get a lotta commentary. Any thoughts as to their merit as a general purpose defense / match optic? Regards - GCF

Well since you added in field and defensive I would say you want a rig composed of: Bushmaster 14.5"-16" Flattop (Fluted HBAR, M4 or lightweight) if you want more accuracy than these chrome lined barrels offer then go all out and get a 5.56 chambered Krieger IMHO. Aimpoint, Eotech, Trijicon TA31/TA11 or Trijicon TA01NSN with DrOptic or Aimpoint sight all with ARMS 40 BUIS KAC 2 stage trigger or Accuracy Speaks single stage trigger KAC FF RAS, KAC RAS 2 or ARMS SIR Either no brake or a KKF brake You will want a shorter stock than factory A2 length. This could be an ACE stock, A1 Cavarms stock, fixed VLTOR or Magpul etc. Also consider a Surefire light if you will be using the rifle at night and a foregrip to help with recoil and to supprt the weight of all this on your rifle.

As previously mentioned, you need to decide what division you'll shoot in. If in USPSA/IPSC Limited (Standard) division, then no optics are allowed (iron sights only). If you're shooting USPSA/IPSC 3 gun matches, then you'll need to make the minor power factor (PF) of 165 (bullet wieght X velocity divided by 1,000 = PF). You can make minor PF out of a 16" barrel with SOME factory ammo (Winchester Q3131a for instance), but it has to be hot ammo. I'd stay away from any barrel shorter than 16" for that reason. Check out www.uspsa.org for the rule book. I also like my JP single stage trigger and my Smith Enterprises post-ban brake. There's a good 3 gun forum on Brian Enos's site.

DevL, I've seen one TAO1NSN with DrOptic on it, the mount was a custom job. Does anyone make an off the shelf setup like that. I'd love to get one.
