M16A4 Accuracy?

The AR series are an inherently accurate system even in stock form. However the acceptance standard, and appropriately so, is 4-6moa (I forget). In case thousands be need spit out by whoever bids on short notice wartime production.

Ammunition and then FF rail was identified by a SOCOM study long ago as a marked, easily adopted, improvement in accuracy. Additionally the heat sink qualities of FFrails have benefits

FF rails aren't, specifically, being "resisted". It's just a matter of priorities and infrastructure. Smaller, more agile and capable units, with different mission sets, can adapt individual training and logistical requirements quickly.

What would the cost vs value of changing a rail system service wide be when maybe 1% of users could utilize or notice the improvement. The current rails get the job done.

1-2moa is much rarer than bantered about the www

Or on the range. It is amazing how much better people's groups are before I start watching or asking them to show me what they can do.

I shoot some heavy varmint matches with a Hammonds 6PPC. Even in this community of the holy grail of accuracy that same thing happens Greg.

I was looking at a similar build. The only think you may want to look at is a 1/8 bbl with a more full contour.

I feel the KAC M5 is plenty rigid. You could do worse.

Personal opinion, I think the Army over built the DMR. The USMC has dropped a lot of bad guys using the above setup.

For personal use, you may want to look at the Federal Sierra Match King 69gr BTHP. They were the heat a few years ago but have fallen out of favor against some of the newer loads. Never the less, they are plenty accurate and still lethal.

I built one of these last year using the BCM upper as well. Accuracy with IMI M855, Lithuanian M855, and Spanish SS109 generally hovers around 2 to 2.5 MOA. With my handloads using 77g SMKs the groups generally go down to 1.5 MOA, but occasionally run a bit tighter than that. This holds true out to 300 which is the furthest distance I've shot this gun at to date.

For a service type rifle, I'm plenty happy with how it shoots.

I finished my M16A4 clone about a month ago: BCM complete upper and BCG, TA31RCO-A4, KAC M5 RAS, Bushmaster A2 lower, Harris Bi-Pod.

I wanted to be able to take full advantavge of the BDC so I purchased a case of PMC M855. I have had the rifle out twice now, the most recient being yesterday. The best I could do was 4" at 100meters with a 5 shot group.

I'm frustrated.
