    I know that I have been asking a lot of questions, but I am curious as to what you all like. I am curious what you all think is the best barrel length for a all around rifle. I want to be able to hunt accurately and still be able to clear a room or house with my rifle. I am wanting something that is accurate and yet still easily maneuvered in tight places. Is there magic length that can do everything that I wanting? Can I do everything that I want to do and not have to buy to separate uppers. Thanks guys and gals. I know I am a pain, but I really think that the people here are a untapped knowledge base for me to break into. Thanks again for all the help.

    You mentioned "uppers". Are you asking about the barrel lenght for an AR?

    I went with the DPMS Lo Pro. 16" bull barrel and a flatop receiver. Your preference echoes mine. The only drawback is the additional weight. I can install a 3X9 scope to hunt with, or change out the riser and scope for an iron sight riser, flip up my gas block mounted FS, snap up my tactical sling and go to work close in. Works for me.

    Define for me please: YOUR level of accuracy?

    If you are talking minute of bad guy, able to hit the 8" pie plate that a hunter needs at 150 or 200 yards, and still be able to go room to room ( :eek: ) to clear a hypothetical house - A 16" barrel would probably be fine.

    If you want tighter groups, you have to get a better barrel, a longer barrel, a combination of the above, or you have to factor in other issues into the build itself.

    Example: A pencil thin 16" GI Chrome barrel is not going to be as accurate as a bull barrel, Krieger Custom that is 16".

    There are a lot of variables when you start talking "accuracy" - because it's all relative to what your definition of an accurate weapon is.

    Help us help you.

    I have a bull barrel now and the weight is way too much for me to be packing around in the woods for any long period of time.

    For me, accuracy means at least 1.5-2.0 inches at 100 yards. I want to be able to put a red dot on for (hopefully) 3 gun matches then put on my 3-9 or 3-12 for hunting.

    Does that help any?

    Thanks again.

    It depends on the barrel. I have a Colt 16" "pencil barrel" that will shoot 3/4" 100 yard groups with the right load. I have a heavy barreled 20" that will shoot 1/2" or better at the same distance. I have found the sweet load for each. This load may not shoot nearly as well in a 16" bull barrel, it all depends.

    FWIW, a decent 16" half heavy chrome lined barrel will suffice for most work. If you are shooting prairie dogs at 300 yds, you need something a bit more specialized than that.

    I missed your response. Thanks to Robo for answering and bumping you back up on the new post list.

    Have you thought about having your existing barrel fluted to save on weight?

    You already know how it shoots. Shave off a little weight and you are right were you want to be.

    Probably cheaper than getting a new barrel, having it chambered and starting over in ammo selection again....

    I talked to a gunsmith today about shaving some off of my barrel all around. I was thinking about just having the barrel put on a lathe and have a lot of the barrel taken off. This gunsmith told me that if I were to do something like that, it may hurt my accuracy and may make any stresses in my barrel more elevated because I am taking the back bone out of my barrel.

    This particular gunsmith told me that as long as I got a barrel that said "mil-spec" on it, I would have no chamber issues with the barrel and my reciever. I am going to go to Knob Creek's machine gun shoot this Saturday and see if maybe I can find a decent deal on a good barrel. He said that he would change the barrel for a reasonable price and then after I sell my Hoyt bow I can buy a new reciever and have my barrel put on that new reciever.

    What do you guys think about the information that I got from the gunsmith today. Do you think that I could have a good barrel put on my reciever where I could get the results that I am looking for? Do any of you guys that live around Knob Creek think that I may be able to find a good deal on barrels at the machine gun shoot this weekend?

    As always, thanks for all the help guys.

    Why are you going to pay a guy do something you can do yourself in just an hour or so??

    Junho - one of the members here, had no AR experience and built his first one from the ground up.

    If you find a barrel - you can change it yourself.

    Or you can have your barrel fluted and save weight that way.

    I wouldn't recommend turning your barrel on a lathe and taking off a lot of weight that way either. A little weight, sure, but not a lot of weight.

    Good luck at the shoot.

    Casey,

    You can check out this site:

    Shop/Machine Services at Adco Firearms

    They do excellent work with barrels, and aren't too far from you. Or at least you are closer to them than I am, and I've had them do barrel work for me in the past. Good folks and excellent service. Just tell them what you'd like done.

    But I have to agree with the info you are getting on here. You could buy another barrel and put it on yourself, no chambering required, and have it up and running in an hour, most likely less. I'm telling you, that DSA M4 barrel for $175 is a hard deal to beat.;)

    I got my rifle the way I want it...minus some good glass.

    I don't know if any of you care, but I just got finished putting new furniture on my AR. I purchased a Double Star HBAR upper. I bought some tan furniture for it from the same company. I bought a Magpul flip up front sight to go on the gas block to go with my flip up rear sight I got from a buddy. They had the same flip up rear sight there at the machine gun shoot that I have for $130. I think it was a Matach? Does that sound right? A B.U.I.S.? I think that is what it was anyway.

    The upper is not chrome lined, I hope that won't make too much of a difference, but I hear that they are more accurate that way. I will post pics as soon as I can. I am kind of pooped right now, so I am going to go to bed and I will try to post pics tomorrow. I love it though. As long as it is half way accurate I will be extremely pleased.

    Thanks for all the advice people, I appreciate it.

    Congrats Casey. Sounds like you are becoming more familiar with the AR platform and that is NEVER a bad thing.

    Looking forward to some pictures and the mandatory Range Report. :D

    Well, I work second shift, so i will be at least a week before I get a chance to go to the range (I go back to work today). I have to say that I am happy with it though.

    One thing did happen though and I don't know if I should the gun or not yet, maybe someone could let me know. While I was taking the stock off, I didn't hold the nipple in that holds the buffer in place. I never could recover the spring, so I took an ink pen apart and used the spring from it. It fits great, but is not as stiff as the original spring. I was wondering if that would make a difference or not.

    If you all think that it will be a bad thing to shoot it with that spring in there, could someone tell me what that spring is called and where I could find one. Thanks guys.

    Well. It's only "important" if the weapon is taken apart in the field.

    However. For a grand total of about $2/shipped. I would recommend ordering a new one. :cool:

    Ok, now I need some glass. I was wondering if anyone out there made a 1-4X Acog clone that would be reasonably priced. I want something that I will sting that I will still be able to use my backup iron sights with, but still be able to zoom in a bit while shooting at longer distances. Is there anything like that made, am I just chasing a imaginary thing here? If so, that is fine, I will settle for a 4X with quick detach mounts.

    Thanks
