Default First service rifle

Between a RRA NM A4 lar 15 w detachable carry handle and say the A4 NM CMP 2016 railed handguad aro784 upper what are the pros and cons? Will the fixed front sight ever interfer with a scope? What if any advantages does the rail have? Btw the WOA A4 service rifle optic upper 1-8 for $635 is attractive also. I have yet to absorb all the rules and seems they change every year from what Iím reading so to buy once for best results and options is what Iím looking to do. It would be even better to possibly find a lonely ar service rifle close by to trade one of my garands for if the stars lined up. Wide open to suggestions.

I have a RRA/BCM A4 combo with a Hi-Lux 1-4x34 XTC using Nightforce low standard rings on a WOA 10MOA base.

It co-witnesses with the FSB front sight at 1X. The FSB is blurred and not a distraction above 2X and essentially not an issue all the way from 3X to 4X.

The Service Rifle rules are fairly stable compared to the MMR rules. The way the MMR rules are written for 2019 a Service Rifle is the way to go for the MMR Unlimited Class.

The FSB can be somewhat noticeable. I would use it to help eye alignment consistency, but it distracts my dad from center reticle focus.



As much as I like a rifle to come with sights, if you're smaller statured and not likely to reach the sling swivel in prone, the 2016 "A4's" rails may be better and the collapsible stock very helpful Offhand.

Yea, I forgot to mention about using a collapsible stock.

I have a UBR Gen 1 on mine.

Go with the WOA option. Match upper shipped right to your door at a wonderful price. This is the style I like:

I have had great success with the Wylde chamber with 80s. I don't like quad rails, they hurt my support hand when in prone. You can build the rest of the rifle on a cheap stripped lower. Popular options are a Geissele match trigger and a weighted first generation UBR adjustable stock. If you end up buying this stuff to replace parts, it turns out to be wasted money.

That is about what I had talked myself into, just wondering if it was the right choice. 1-7 or 1-8 ? Why? I will most likely not be reloading for it also. From what I have read doesn’t seem to matter; but I believe RRA all come 1-8.Thanks for the insight.

RRA NM A2/A4s

Wylde chamber

BARREL:
20-inch Air Gauged Heavy Match Stainless Steel, Cryogenically Treated, 1:8 Twist

If your shooting to 600 yds. for a typical XTC match using 75s a 1:8 twist is fine.

Here's another tip. Everything service rifle/ high power has all ready been tried, been there done that, moved on. Your not going to reinvent the wheel. There's lots of great advise here. Also if guy like Roosty or someone else, gives you advise, and you happen to look at their profile and you see badge number xXxX, you probably should listen to said advise.
