SR-25 EM Carbine History

Post by KevinB »

Shortly after 9/11 elements operating in Afghanistan noted that the M4A1 even with our (KAC) MRE FF RAS, and S&B Short Dot was not up to the task of going from the CQB fight to the edge of the villages or out in the mountains, and while the 18" Mk12 Mod0 and Mod1 are capable in the accuracy department, that they where neither very handy for CQB, nor would 5.56mm, even with then newly adopted 77gr AA53 round (Mk262) capable of barrier penetration at range. Larry Vickers did a segment on Tactical Arms to air this year where he talks about why the M4 was picked over the MP-5 for CQB, as to somewhat paraphrase him “ you sometimes need to step out of the house and make a 100m or 200m shot”, he then relates to the 7.62mm SR-25 EM Carbine, and the 7.62 Battle Rifles, “well in Afghanistan, sometime you need to step out or go up on a building an make a 400-600m shot, and 5.56mm is not ideal for that”.



We had built pre-ban SR-25K 16" guns, and some other 7.62 carbines, however they where not really designed for the “M4 type” roles that where being envisioned.



We came up with the SR-25 14.5" Battle Rifle,

Image

With the idea is that it was very similar in appearance to the M4's and not going to draw undue attention, as well unlike the majority of systems, it used the same manual of Arms as the M4/M16, so soldier who have years on the M16FOW, don't have issues relearning drills, especially valuable under stress.



7.62mm is more optimized in longer than 14.5” barrels and really wants at least a 16" barrel, and a lot of concerns about the reliability of the 14.5" gun were being given, so shortly after the 16" SR-25 Battle Rifle was developed, which was really just a longer barrel.

Image




We had never envisioned a 7.62mm gun being run like an M4, and especially with a suppressor neither the 14.5 nor the 16" gun where at the reliability level that was desired.

Image
Especially suppressed, I ran the 16" SR-25BR at classes, and demos.

Accuracy even with the chromed barrel was always good, sub-MOA and a fair amount under the 1/2MOA mark.

It is a good gun, but in high suppressed round counts it got dirty and finicky.







Near the first quarter of '09 we started work on a PIP of the 16" gun, as well as the 20” M110.

High-speed video, lots of rounds, more high-speed video, changes to the gas system, and more rounds and video, a lot more stuff and changes to the bolt carrier, the recoil system resulted in the SR-25 EM Carbine.



At the same time, the optical industry was busy working on a 1.1-8x scope to give the user the ability to take advantage of the added capabilities of the 7.62 round.

Image
What we ended up with was in our opinion the finest 16" 7.62mm gas gun on the planet.



We shot several EM’s for over 1,000 rds fully suppressed with no additional lube, with no stoppages

We have done extensive lifecycle work on the guns, endurance testing etc.



We wanted to build the best gun we could, so if someone on a mountain top in Afghanistan or wherever else needed to have a gun that would go and go and go, it would.

If he has to dump it in snow to cool it down, it would go and go and go.



With well over 50,000 rounds thru it, including a day where Mr. Knight and I stood in a puddle of muddy water splashing the gun to cool, we feel we are there.



Unlike our previous carbines, which we showed at SHOT (I have a pic somewhere of me holding the 14.5" gun at SHOT'04 when I was still in the Canadian Army) and never really publicly released for sale, we wanted a short 7.62 like this this gun to be our Flagship.



So its here, and available.

Great info, thank you for posting this.

I'm curious as to why the EMC doesn't have M4 feed ramps?
Were any guns tested with M4 feed ramps or was this a non-issue?

It requires a VERY tight tolerance, and can lead to the tip of the round being deformed from what I understand. Considering the gun is built around accuracy I'm guessing KAC went with what they knew worked. It'll be interesting to see how the Larue and LMT offerings handle with the extended feed ramps.

Just run good ammo through the gun, no square rounds, and it should do just fine.

Kevin as I said on M4C, thank you very much for the perspective. Now if you'll excuse me I gotta go load up about 600 rounds to run through the EMC this weekend.

Kevin, great info on the history of KAC's BR/Carbine. I am sure you guys pound fist and hammers to perfect these great platforms. I could only imagine the satisfaction from hard work of KAC, and knowing that our military forces continue to have the cutting edge of weapons technology.

Has KAC ever tested an 18" barrel on this platform? Are the MV gains not worth the added barrel length?

Well I looked at one from the batch I received and looks like things stayed the same:
URX II
Mk 11 style lower assembly (no ambi bolt release)
Carbon cutter serrations on carrier
And the rest of the standard features.

Thanks Casey for the info. I figured the next run would be ambi. Not that it really makes a difference to me.

Was the one you looked at recently produced? I figured they were making M110c's for the military right now.

Very interesting read. This just makes me lust after the SR-25 even more. I'm going out with some guys from 10th Group in a few weeks and will get a chance to play with the M110.
