Ok how to set up an ar for competition?

[yocan]

I have a lower. I don't think brand matters all that much. I believe my assembled lower has a 4.5 lb trigger or some such weight.

I'm looking at buying a 24" barrel off a person on here with 200 rds through it.

So furniture and trigger suggestions? I'm 6'5" my wingspan is 6'9" so for prone I think I'll need a longer tube (thinking 12/13 inches) I assume free float tubes are the way to go on this.

Trigger I have no idea what I'm doing

Stock on my carbine shoot rifle is a magpul asr Open to suggestions, just curiuos about with how big I am if that will make most only semi adjustable length of pull rifles not adapt sufficiently for me.

I have a 1.5-8X scope that will hold me until I have the money to buy a better one.

I read somewhere that some people for precision builds use loctite to bed the barrel into the reciever... is that just an idea someone had or is it worth doing?

What kind of competition?

Prone, across the course?

well I'm going to be learning on a 600 yd range. whatever most competitions are. I'm doing this more as a learning how to shoot thing. Lots of guys just said come out and shoot with them they will help me out. A lot of F class shooters, but for the moment I just plan on shooting with glass seeing as I'm in the military and we shoot with glass.

They told me all I needed was a longer barrel to start shooting with them but if there is stuff I need different I"ll go ahead and get it now.

part of me thinks it would be cheaper to go with the 556 for this just get a 24" heavy barrel for it and load 70+ grain bullets but I know the 6.5 would run it much better.

The most common is across the course followed by F-Class and prone mid range. Across the course is shot at 200, 300 and 600 Yards.
Mid Range is shot at 300, 500 and 600 yards. find out what kind of competiton you plan to shoot and we can advise you on the best equipment selections. They are very different for the different disciplines.

will do but my only concern right now is slow fire, probably won't shoot a competition for a year, really doing this to learn how to shoot. If I end up in a combat zone I'll probably end up carrying a 7.62 either an ar10 variant or something similar in size. Don't care which competition really as long as I get better I'm on a pretty steep learning curve at the moment so yeah..... too much data not enough experience to really make good particular decisions so hoping for universal semi cost effective advice.

they don't have a 500 locally so I'd assume were talking across the course for the main focus right now just googled it and I do believe that is what they shoot the most.

For an AR? Keep it as close to the no frills look as possible. No free float guards, no muzzle brakes, no scope, no aftermarket anything. Keep the standard rifle stock/handguards, grip, front sight base, muzzle device.

In other words, put nothing on it, except a sling.

Now, basically anything that doesn't effect the appearance of the rifle is good to go. That means you can have a nice floated barrel (special handguards for this), trigger, and whatever else you can cram into it that people can't see or that doesn't effect the outward appearance.

If you want to shoot F-Class, then move to a different rifle, a bolt gun in .308.

For the Service Rifle (or EIC matches) Rambozo is offing some good advice go stock AR (either 15 or 10) then go for build from there.
F class I would offer a different caliber choice than the standard .308 which is the .260 Rem but not shooting that discipline I only base that on the ballistic tables. the Bolt gun rules in this class.
If one is shooting a NRA match however there is a class called NRA Match rifle which is wide open on how the rifle is configured and what can and can't be done to it. Which explains why many are asking what discipline your intending to shoot.

F class I would offer a different caliber choice than the standard .308 which is the .260 Rem but not shooting that discipline I only base that on the ballistic tables.

While I didn't specify, the recommendation was geared towards F-TR. Someone getting started out, would likely be better served in that class. There is a much more distinct and lower equipment ceiling, and so it doesn't put you in a class trying to play catch up to hotrod equipment and belly benchresters.

Trigger I have no idea what I'm doing

I read somewhere that some people for precision builds use loctite to bed the barrel into the reciever... is that just an idea someone had or is it worth doing?

Geissele makes a great trigger that works in combination with different sets of springs to make whatever kind of pull weight suits your needs. Depending on the competition guidelines they'll have one that fits.

Loctite. yes. it's essentially like bedding an action. it removes the gap between the barrel extension and the receiver. Just smear some blue loctite around the extension and the inside of the receiver, some anti-sieze on the receiver threads, and torque is down, back it off and re-torque several times to set the threads, and set final torque to 30ft lbs then turn to the next gas tube opening.

For F-TR you would be at a great disadvantage shooting a Grendel Gas Gun. You'll be shooting nines with the same wind call error as your fellow competitors who are still catching 10's with their tuned up bolt rifles shooting 400 fps faster. The F class x ring is 3" at 600 yards, the MR target which is used for mid range, and across the course is 6" at 600 yards. Also, I think for F-TR you can only shoot .223 or .308 anyway.

If you really want to learn to shoot under a variety of conditions, and are willing to put in the work, which few are, the across the course type competition will help you do that. With a Grendel you will be forced to shoot in match rifle class because it is not a legal service rifle no mater how it is configured. However, it will keep up with the majority of match rifles, and will equal or better the service rifles.

For across the course you shoot 200 yards standing with one minute per shot. 200 yards sitting rapids with ten shots and a mag change in 60 seconds, 300 yards prone rapid with 10 shots and a mag change in 70 seconds, and 600 yards slow prone with one minute per shot. Scopes are not common, and all the better shooters are shooting metallic sights. Optics are more of a disadvantage.

Mid range is either 15 or 20 shots each at 300, 500, and 600 shot prone only. Most of the better shooters are shooting a single shot bolt actions so that it is more rigid than a repeater. But you could use a Grendel from a sling in this type of competition effectively and move up to the top 15% or so of the shooters and you can use a scope. Just be prepared to se how bad your hold really is.

LOL, Rambozo I misread your post - see that is why I stated a caliber choice based off ballistic table not experience. Some know far more than I on this series of discipline.

that was an awesome response. Why are scopes a disadvantage? weight?

I plan on using my DM style scope which is a 1.5-8X (wish I had the money for iors new 1-10X but I don't) because I want to learn to shoot that way. It also has the advantage of a diopter adjustment and I'm not quite 20/20 vision. This is my learn to shoot gun I'm not looking to win just not go crazy on the insanely steep learning curve i'm going to be trying to climb over the next 3 years.
