I have been doing a lot of research and I have only been able to narrow it down to a couple of preferences. If anyone can suggest a preassembled brand model (preferred in order to make it easy) or the best upper and lower mix I would very much appreciate it! Here's my criteria: 1. Longevity/Durability: Looks like Chrome-lined barrels are the best for this? Rifle would be Chamber in .223/5.56 and is mostly a plinker gun with some long range accuracy capability. I do not need competition level rifle, but I want something more than a casual/cheaper plinker rifle would provide in terms of accuracy. I hand hold for shorter distances, but for 200/300 yards I would use a bench rest or bipod. I also reload my own ammo, so a rifle that won't cause issues with this would be great, I use average or lower power rounds. I only shoot paper targets. Also, best twist rate? Not too sure on what fits my needs on this. 1:7 1:8 1:9 :huh: Occasional rapid fire will be used, so I want something that can take some abuse, bust still do a good job at the 200/300 yard range. From what I have researched and asked about stainless steel is more accurate but wears out faster. Looking to shoot 120 rounds a week on average. Any experiences with the material used in Glocks, melonite I think? 2. Quad Rail, Flat Top, Free Floating Barrel: I want room to put some scopes/red dot & magnifiers on, as well as a foregrip. No lights or lasers. I've picked up and gotten to shoot a few ar-15s, but I do NOT want a "fixed" or "mounted" iron sight. I would prefer to put on my own flip-ups as a backup option instead. Free Floating barrel for extra accuracy boot rather than d-ring and having a long extended rail seems like it meets my criteria. No carry handle needed either. 3. Ease of Use: Easy to take apart and clean, little effort does a great job. I will clean after every range use and will probably average around 120 rounds a week. 4. Quality: Reliable, no known issues. I've looked at Smith & Wesson, Colts, Knights Armament, & Noveske. I am not a brand loyal person, I go with what works the best for my needs. I was going to go for a S&W ORC, but putting quad rails in place of a brush guard, and not having a free floating barrel seemed like it would work against me. Am I wrong about this? Looking for an average size barrel length, 16" or so if I recall correctly, and a good balance of weight if possible. Gas piston seems like it would be better than direct impingement from what I can tell, thoughts? 5. Budget: Cheaper is usually better, would prefer to keep it at $1000 and under, but if it makes sense I could go $1500-$1750. $2000 is just getting way to spend and keeps me from getting any accessories for a long time. Any suggestions? Thanks in advance!
