sorry for making a "suspicious" post, i've been browsing the AR15.com page for some days and see plenty of warnings regarding the issue of DIAS, LightningLinks and barrels that aren't 16" - so i wanted to be consise.

Forget those DIAS´s and Lightning Links if you already have full auto parts on your lower receiver. Take them off and treat them like they are last ones in the world if you are not able to easily get new ones. Replace them with new semi auto parts and learn to shoot with accurate semi auto fire (if you don´t already do). Well placed single shot is better than 30 misses, IMO.
I was thinking of buying a barrel from bushmaster, but it requires a lot of paperwork - so If I buy one it will probably be one from a local gunstore (they don't have bushmasters, but some other brand I don't recall at the moment.. maybe "wilson" or something) Anyway, I understood that chrome lined was the way to go, right?

You are right on track. Try to get Bushmaster, Colt (1/7"), CMMG (DPMS) or LMT barrels. These are all chrome lined. It is hard way through State Department but it is worth it, you get barrel that serves you many years.
Wilson barrel are good but usually chambered for the .223 Remington and they are not very reliable with military surplus ammunition due their higher pressures. Wilson barrels good for reloaders and targetshooters, IMO.
The barrrel in my bushmaster is a HBar 1/9 - any thought on how many bullets I can put through It before performance starts to degrade seriously? (maybe I'll put aside the barrel investment for now, as I don't have too much cash.. well, who has when you are a hobby shooter..

I have reached 6500+ rounds mark with my M4 barrel and it still shoots well under MOA (about 30 mm @ 100 meters) so you can shoot the hell out of your 11.5" barrel before you see any signs of accuracy loss. I´m recommend you to focus on parts listed on AGCs post above.
Great list AGC, and I'm especially interested in notes on what parts that most frequently fail/break. Of course there's a difference between rough battle handling from GI's and a hobby shooter when it comes to taking care of a rifle.

AGCs list is very good but I´d like to add bufferspring and H buffer to it.
As a sidenote, I have changed only bufferspring to my M4 after those 6500+ rounds, which includes various brands of surplus ammo (PMP, IMI, RORG, RUAG) and pretty hot reloads without single problem.
Bufferspring I changed was still in specs but Bushmaster tech recommended to change it after 6- 8000 rounds and price of that spring is around $3- 5 so it won´t be a problem.
Where did you buy your Bushy, BTW?
