Hello all - this is my first post on the board. I've been lurking for a few days. I'm in the process of trying to sell my SA XD .40 S&W pistol to fund the build of a tack-driving AR-15. Since I first saw the Bushmaster Varminter reviewed on Gunblast I was in love with it. It's way out of my budget, so I'm thinking I'll build my own. I'll probably outfit it with a Super Sniper because I like the reviews they have gotten, and the price is reasonable. Plus they don't have that "deer rifle" look. Anyway, I want to build the rifle first, then get the optics when I can afford it - so I'll probably fit the rifle with the flip-up sights. My question is this: How accurate will the rifle be once the scope has been removed, and reinstalled? Does the gun need to be sighted in again? Also, what kind of MOA difference will I see between the 20 and 24 inch barrels? I think the 20 looks better, but accuracy is what I'm after. I'll probably never find this kind of distance, but if I ever wanted to reach out to 500+ yards, I'd like to know the rifle was up to the task. I've always been interested in target shooting, but never had a gun that was capable of precision shooting. Will a 20" barrel be any good for those distances? Will the 24" be? Or is the AR-15 .223 the wrong gun entirely for those ranges? I saw a similar question posted a couple of days ago, but it seemed to veer off into the realm of human-sized targets, which is obviously much larger than little varmints. I'm not a service guy (lost a leg in a motorcycle wreck back in 96) - I just want something extremely accurate, on a shoestring budget. Is that possible? Be gentle... |

In response to your question regarding maintaining the accuracy of you sights after they have been removed from the flat top. I highly recommend investing in a LaRue Tactical sight base. LaRue products are second to none and they will maintain accuracy even after repeated cycles of mounting and removing your sight from your weapon. Here is a link: http://stores.homestead.com/Laruetactical/StoreFront.bok hint: look under "optic mounts" |

Your scopes ability to retain zero after removal will have to do more with how good a mount you buy than the optic. Buy a LaRue mount for whatever optic you buy and you won't have to worry about losing zero. Barrel length has realistically zero effect on the accuracy. Quality of the barre, quality of the ammo, and skill of the shooter have the biggest effects. Longer barrel just means more MV (and longer sight radius if you use iron sights). More MV reduces the deflection due to wind and allows for a flatter trajectory. .223 has no problems reaching out to 500y, but the 6.5 Grendle is even better (especially if you want to shoot out further than 500y). |
