View Full Version : Some thoughts on the SR25

For the past few weeks I've been getting some serious butt plate time on Knight's SR25, shot it before but not extensively.

It's not a light rifle just shy of 11lbs naked and empty, similar to the M14/M25.The rifle I've been shooting is equipted with the M3A 10X40mm day optic and no iron sights. Accuracy has been averaging between .50 and .65 moa, not bad for a gas gun. You get the normal first round flyer common with all box magazine fed semi autos, this can open up your group by 2X.

Maintainance wise I've been cleaning the receiver and barrel after 20 rounds, gas guns need this for repeated accuracy. With the gases being blown back through the gas tube the bolt carrier/bolt and locking lug/barrel extension get carboned up in short order. This results in the bolt locking up at different positions, while safe to fire accuracy is degraded by what is in effect changing headspace.Bolt and bolt carrier are chromed though the carrier key is not making cleaning easy. The firing pin retaining pin is captive so you can't loose it like the M16 version. The barrel is a 24" tube 5R rifling with a 1 in 11.29 twist. Remington makes the barrel and it's the same as on the M24 SWS(except barrel is chrome moly not stainless). The 5R makes it easy to clean.

Performance wise I've had no malfunctions of any kind. The floating handguard takes all the stress when using a sling for support, plus the barrel is free all the way to the barrel nut. One thing that needs to be used all the time is the removable case deflector, if not used cases will mark up the reciever and case a twitch for a lefty. When engaging multiple targets the rifle comes into it's own, recoil is absorbed by the weight and gas action allowing quick re- acquisition of the target. Current thought is the rifle can provide precision fire on multiple moving targets under 800 yards, I think 600 is a more reasonable range except under ideal conditions and terrain. One problem with it is you can not get low enough for a good hawkins position(one I like)the design forces you into a high shooting position due to it's pistol grip and the 20 round magazine.

I like the weapon, will it take the place of a bolt SWS...no, it's not a surgical weapon. But as a spotters weapon or DM weapon it is tops. Also as a primary SWS where MOUT is involved and shorter ranges with a high target density it will serve well.

With the above in mind I feel a variable power scope such as a 3.5-10X would be ideal. With a faster ranging reticle and "sniper post" similar to the kahles ZF95 would be a better choice. The "sniper post" is a better choice for low light and shadowed area such as a city, plus is very fast on target. The range finding reticle is of the SVD POS-1 variety using a base line and steps for 200,400,600,800, and 1000 yrds/meters matching the BDC increments. I would also recommend that iron sights be fitted. The folding front and 600 meter rear are great. The front folds down into a slot cut into the hand guard, the rear is similar to the M4 but made in two versions a 300 and 600..the 600 would be ideal. The iron sights would allow the weapon to be used as a normal combat rifle when needed and also to continue with the mission in bad weather when a scope would be blinded(heavy rain and snow)

Overall I've found the SR25 to be the best semi auto SWS I've had my hands on(have shot the PSG-1,M21,M25 and others). I wouldn't mind adding one to my personal battery, I think Knights have done a great job with this one.

Hope I didn't bore anyone with this post. Take care...Jim

Hi Jim,
Good info on the SR25,but I have a few questions.

What kind of ammo did you use in your test? Are 5R barrels more accurate than button rifled? Why the odd rate of twist?

Thanks,
Glen

Hi Jim,

how are you doing my friend ?

Do you believe me if I tell you I'm waiting for my SR-25 next week ?

I agree with you at all,I have one M25, as you already know,but I tested the SR-25 and I wondered about its accuracy.

It's a great piece of hardware.

Hi Glen;

The ammo used is M852, it's about the same as the 168gr Fed Match and BlackHills Match. Uses the same 168gr Sierra HPBT match bullet witha MV of 2780fps.

The 5R barrel has one side of the land angled, this causes less stress on the bullet and jacket. This cause less deformation and better accuracy. A side benefit is the land catches less copper and fouling making it easier to clean and they say less barrel wear..we'll see on that one. Remington makes the barrels for Knights on the same machinery used to make the M24 barrels, it's hammer forged and has 5 lands and grooves. Configuration is the same as the M24 but made from chrome moly instead of stainless steel as the M24. The rifling is modified from the Russian AK74, 5Russian.The twist is a compromise of "light" bullet 1 in 12 and "heavy" 1 in 10 so it will shoot bothe the 168gr and 175gr equally well. I've shoot some 175gr M118LR and find it to be nearly as accurate as the 168gr but the 1 in 11.29 leans towards the 168gr. When compared to a button rifled barrel the hammer forged bore seems smoother and is said to be less stressed, I know when looking with a bore scope it shows much less grooves and striations under magnification.

Glad I could be of help. Take care...Jim

Hi M;

Good to hear from you, think you're going to like the SR25. It's not a bolt rifle but I do like the weapon. Accuracy is exc. for a gas gun with .50-.65moa being the average with M852 7.62X51mm Match.

Take care, my friend,ciao...Jim

Currently have a Kahles ZF 95 mounted on the rifle. It improves low light use of the SWS to well after sun down. The ZF 95 has the "German Post" or "Sniper Reticle" and a SVD type ranging reticle. The heavy pointed post and side posts show up great after dark, if a moon is present as the past few nights you are good to go 'til it sets, add snow and your good 24/7. The BDC is set for the 168gr match bullet at app. 2700 fps so is right on for M852 (which the rifle likes).The ZF 95 is a 10X42mm with 26mm tube and compares well to the Leupold 10X40mm with 30mm tube.

Have to say this is a great set up for fast target acquisition, ranging and engagement. At the range practical for the SR25 I feel it's ideal, the pointed post is not as precise as a fine cross wire but much faster in use and accurate enough for the range and type of shooting involved. Plus vastly superior in low light situations. I understand that Leupold has the reticle available, this reticle in a M3 would be outstanding on this rifle.

Take care...Jim

JY,
What do you think of the 24 hour day/night scope for sale in U.S. Cavalry? Its the one produced by HITEK international.

The only down sides that I see is it not being waterproof, & low magnification 2.5-10day/1.5-6night.

Thanks for any opinions.

Hi Bob;

I've only had my hands on the Remington version of that type of scope system. It does do what it's advertised to do, but and a big but, you cheek weld varies between the two. When you attach the night module and it extends far back beyond the action requiring a strange angle in your neck or adjust your whole shooting position. The HiTek replaces the whole ocular with the NV attachment but still it looks like it will result in the same overlength problem. Both solve the problem of switching complete units for day and night operations, but are a compromise so have minuses not found on dedicated units. Price wise you can't beat either if you're paying out of pocket.

One thing though, I'm not to familar with HiTek, I know a lot say they are made in the USA but some use Russian tubes. If it has Russian tubes or electronics be very careful, Russian tubes seem to go to air very fast and suddenly. Also Russian GEN ratings are not a match for ours, their Gen II is more like our GEN 0 or a lower quality GEN I. If it uses Litton or ITT US mil or Com spec tube no problem. It's not a Simrad but will do the job, also unless you live in place that has NO light sources like up here in the Rockies a GEN II will serve you very well or what they call a GEN II+(gets a little more sharpness by using infrared similar to GEN III).

Hope you can decipher these ramblings.Take care...Jim

10-4,
I was wondering about the change in cheek weld too.It seems like a fairly easy problem to fix if they would just extend the day sight adapter to the same tenth as when the night adapter was installed.

I didn't know that Remington had a simular scope avalible, I'm going to have to look into it.

Yeh those demoNRats are trying to highjack the Whitehouse(:.I hope that the Florida Secritary of State isn't blocked by a judge tomarrow, when she tries to force them to give up & certify their precint ballots or to be disregarded for being to late!!!! http://www.specialoperations.com/ubboard/cool.gif

Hi Bob;

The Remington version attaches to the scope you already have, attaches to the ocular. The unit also doubles as a NOD for general use. When attached you have to crawl WAAAAY back on the stock. Probably more versitial than the HiTek and US made.

Latest on Gore from the local news,4 Denver, is that Gore is trying to delay certification of the Fla. vote until the E.C. meets. This will allow the E.C. to throw out Fla. and the current electorial ballots held by the candidates will win..Gore who still holds the most right now.This would explain the GOP wanting to impound the N.M. ballots where G.W. just took the lead from Gore by 17 votes, and the possibility of recounts in Iowa, Wis., and Ore. To try to get a majority from these. If this is true, it's the best evidence of the Democrats trying to steal the election, typical Willie move, bend the law to further your personal gain "define lawful votes".

Notice too that the "judges" in Fla. are a democrat and a Republican, if they can not agree on a ballot a third breaks the tie...a democrat...think that it's a fixed crap shoot?

take care...Jim

Got that right, the wording had a few weasle words in it though. Today will tell if the ruling worked. Sat. if the sytem worked. That News 4 story above was repeated by the other stations in Denver yesterday and today.

take care Bob...Jim
