A2 or A4 on NM / DCM Rifle
Hi,
Need a little help....
I looking to get a match rifle for high power 100-300 yard matches.
Leaning currently toward a RRA NM. My sticking point is the A2 or A4 handle. As the carry handle on a A4 means another moving point, how much can this affect would this have on the accuracy? Any potential change in POI with removal and reattachment? Or am I just over-thinking it?
Thanks.

A3 MAY not return to zero...but why would you remove it? Then again, if you buy the rifle strictly for HP matches, why not A2?
A2 if you won't be mounting an optic.

My 2 cents. Get the A3.
I have a NM RRA A2. I have shot about 6 matches with it and just 1 in the past 2 years. I would love to put a TA11 on it and make it DMR type rifle, but I'm stuck with an A2. But, because I have BRD I have 3 other A3 rifles with optices on them. The NM is a great rifle and I wish I could easily put a scope on it.
Will the a3 take all the NM sight parts?
if u are ONLY going to shoot Highpower then A2. If you want to use it for any actiivty w/ a variable scope other than 1 power then A3.
I got the RRA NMA4.
I test my reloads with a Nikon buckmaster mildot scope on it.
When I have the Irons on they've never moved.
NMA4 and don't look back.
Is there enough elevation in the carry handle to get out to where you need to be? I heard it won't make it to a thousand if you want to shoot the long stuff.
If you drop the front sight post you can easily get that carrying handle to 1000. You have to use both front and rear elevations and understand what 1 turn of the front post will do.

Yep. The A4 handle can have either 1/2 or 1/4 MOA.
I like the idea of being able to put a optic on it for stages that allow them.
you are right the front post for 1000 each turn is 5 minutes approx.
you have to do it either way a2 or a4
My bad math.......5MOA
Each click/notch on an A2 4 position post would be 1.25 MOA for 5 MOA total. You will need 4-5 complete turns from your 600yd zero to get to get roughly to 1000yds. It's 20-25 MOA from 6-1000. Roughly... With an 80 Sierra at 2820 fps (25.5 N150 will do it, no pressure.. Start at 25.0 and go up. 26.0 will work, but 25.3-25.5 is very accurate..) it's a 20 MOA climb to 1000. If you shoot COM at both ranges. If you shoot COM at 600, and do a hold that's between the bottom of the black and the frame, which is smaller than the 10 ring at 1000, and is a very common hold for service rifle at that distance, you may need the 25 MOA. I shoot COM at 600 and top of the frame at 1000. I don't use as much come up. I also have been shooting M14's. But it works with AR's and 80's just the same. If you shoot a Palma course you will start off at 800 anyways and have unlimited sighters at that distance. Then 2 at 900 and 2 at 1000. To get to 800 you need about 8 MOA from 600, then 900 about 5 MOA from 800 and then 1000 about 7 MOA from 900. That will get you on paper. The wind will kill you way faster than elevation will. Hope this helps.
Another thing to consider. The handle slot on A2's is wider then on A4's. It's easier to reach through it to close the bolt. This is important when you load in position wthout taking the stock out of your shoulder (right handed shooters). A lot of people shoot slow prone keeping the stock in their shoulder for the entire stage.
Lenny, do you keep your rifle in your shoulder during the entire string in slow-prone?
A2.........

This is true! I can remeber the first time slung up I tried to reach my fat fingers through the A4 carry handle and it was awkward and uncomfortable.

Yes, I do.
Just reach over it. Easy.
