I am building a rilfe on a Eagle Lower and Bushmaster Dissipator 16" barrel. This rifle will be used for shooting on weekends. I plan on putting many thousands of rounds through it. My goals are: Reliable and accurate. What factors go into assembling an AR-15 that is: 1st-reliable and 2nd-relatively accurate? Are there any special pitfalss that I need to look for when assembling this rifle? |

1. quality name-brand parts with a mil-spec M16 chamber instead of a .223 Remington boltgun chamber. Armalite, Bushmaster, Rock River or Colt are the first that come to mind. You need quality, experienced assembly if the upper half doesn't come already assembled from the factory. A chrome-lined milspec barrel like a bushmaster or colt A2 type, with a full standard buttstock would be most reliable right out of the box. 2. good sights, good trigger, good barrel, good sight-in. The best barrels for accuracy will be at odds with some of the reliability factors you want due to tight match chambers. A nice Olympic Arms Stainless Ultra Match should be good for 1/4MOA or less if you do your part. You can do even better by paying big bucks for an air-gauged heavy match barrel. Use quality, premium match ammunition, or quality premium handloads to squeeze the last bit of consistency from your loads, and match your loads to what shoots best from your rifle. A regular mil-spec chrome lined barrel should be good for 1MOA and sometimes even better - which is beyond the consistent performance of your average iron sights shooter. If you want, need, and can shoot to 1/4 or 1/8 MOA, the match barrel setup and careful choice of loads can get you there. |

I have an A2 upper that I have had for years. I am buying the Bushmaster barrel assembly and installing it on the upper receiver. I have purchased a DPMS parts set for the upper and will be installing those also. I will be purchasing an Eagle Lower and putting a DPMS or Bushmaster lower parts set and an A2 stock in and on the Eagle lower. |
