| I am putting together an AR for each of my three kids and I really wanted to do 20" A2 types. I have looked at a bunch of threads here and else where and what I am running into is it seems 1:8 would be the best compromise twist rate. I just have not found many places that have uppers in that twist that fit into my budget (for three uppers). I could get 1:9 or maybe 1:7 from various places but Model 1 is about the only place with a reasonable 1:8 and I am leery of them. So what do you guys think. I just want these to be good solid rifles for them to have going forward. I don't really have a hard timeline to purchase them in but I do want complete uppers so I can put the lowers together and put then just put the upper on. I have thought about going with a flat top and a detachable carry handle and once they are good with irons they could put something else on (with their own money). I am just at an impass as I can't spend 700+ on each upper. Thoughts? |

If you guys are just sport shooting and don't require something incredibly reliable, I'd recommend this Stag Arms upper. It's got everything you need and a detachable carry handle. http://www.stagarms.com/model-4h/ Define "incredibly reliable" also I just wonder if going with a 1:9 is going to limit me too much on bullet selection. Granted I know the vast majority of ammo made is probably 69gr or less. Just have not been able to decide it the 1:8 or even the 1:7 would be worth the trouble/expense. I have read several threads on here that talk about how the length of the barrel does effect it's ability to take somewhat heavier bullets for any give twist rate (at least that was how I interpreted it). I have went back and forth several times in the last few weeks between the 8 and 9 rates. The price of the stag is nice. |

What I mean by "incredibly reliable" is, if youre not looking to shoot in a competition or in a battle situation, where a jam could either take points away from your game, or put you in a sticky situation, the the stag is a good gun. Low twist rates are good if you plan on a high grain ammo. For instance a twist rate of 1:7 will stabilize a bullet grain of 72 or greater better than it will a bullet with a lower grain, say 55gr. The heavier the round, the more twist you want. If youre planning on shooting walmart ammo w/ 55gr then you should pick the 1:9, it will stabilize better than with 1:7. 1:7 will actually cause you to lose accuracy with a smaller grain. It goes, hand and foot, 1:9 wont stabilize 72gr like it will 55gr, it wont spin the bullet fast enough and itll lose its spin sooner, making it much more prone to being affected by wind, air density, and even humidity. the farther you want to shoot, the more grain and more twist you want. the heavier bullet maintains a fast spin keeping the trajectory uninhibited for a longer duration, allowing you to make less adjustments for windage and elevation at a greater distance. |

How old are the "kids"?. The 4H features a heavy barrel and may be a little heavy for the young ones. I have one and love it but my stumble around in the woods rifle is their 3G. 13,11 and 9. I may end up having to put the uppers together to get what I want. Thankfully this is not a "have to have it now project" A good friend that puts his own together is asking if I want to go that route. We will see. Thanks for the advice so far. |
