RFB initial thoughts, Range report ***JANUARY 31st ammo test at bottom of OP***

Aside from the Canadian version not having a muzzle break, is there any difference in the barrels vs. The U.S. Rifles?
I emailed 2 different friends down in the U.S. who own the RFB's, and both claim to be getting sub-moa at 100 yards. In fact, both claim excellent accuracy out to 500 yards or better. I've known both these guys for a few years now and I am positive they are honest with their info. When I told them that the range reports up here haven't been very promising, they were amazed.

pbr, please pursue this further. Do these two guys have pet loads that they can provide? Can these two guys substantiate their claims? IE, as most know, even an sks will shoot 3 shot, 1 inch groups every now & then... That doesn't mean an sks is a sub-minute rifle...

Cheers & Thanks in Advance

Can do.

I'll email today, I'm pretty sure they both load their own ammo so I'll ask what's working best so far. I can with certainty tell you that they both did 5 shot groups at 100 yards on more than a few occasions in various conditions. As for them substantiating their claims, Neither are CGN'ers but I have known them since Afghanistan and trust them emphatically.

Like he said -

Those of you who have trouble getting tight groups -

Remember the RFB is a bullpup, in a rest the 2 support points are VERY close together resulting in less stability.

I am testing with an extension forward from the forearm and a monopod at the rear of the stock. If necessary I will extend the rear as well for bench rest shooting stability.

Also the triggers are crisp but heavy - squeeze as slowly as possible.

Will post results when the weather is warmer - I cant get tight groups when I'm shivering ! :eek::runaway:

This is a good idea if the rail is thick enough (without the bipod but on a quality bench rest) --

I got my response from both guys today....
One is getting good results with black hills, but says the federal Gold medal match is working best for factory.
The other is using Remington premier accutip 165 grain with great success.
Both are getting sub moa at 100 yards with the factory stuff consistently shooting both 5 and 10 round groups. ( keep in mind that they both live in the US and can have 20 round mags) hence the 10 round groups...
They are still working on the perfect weights and loads for reloading and will get back to me when they have the best results.
Finally they both agree that the RFB doesn't seem to like the heavier grain and 165 is the top end for accurate groups...

I hope this helps, but I'm still wondering if there are any differences in the barrel between the US and Canadian version....

Aside from the extra 0.5" of length and lack of flash hider or threading, remember that they did ream out the 7.62mm chamber to make it .308Win. Apparently there are different headspaces - I don't really understand the differences myself... I do know that some gunsmiths don't like to ream out chambers because they worry that the reaming may not end up 100% aligned. So this could be one more place to introduce imperfection.
 
I am on a waiting list or two for an RFB. Just for kicks....I called KelTech a few weeks ago, and thanked them for their products, and for navigating the bureaucratic waters of foreign shipment.

The lady I spoke with was kind, and I asked her to crank up production, and get these rifles to a bunch of eager Canadians. She was amused, and undoubtedly thought me crazy (she's a good judge of character).

Hopefully we get a few more of these in country PDW - well, at least 12 more of them....so I get mine!!! JK
 
My buddy got his, lent him a 5/20 mag and some factory (PMC) and hand loads. It was cold and he was in a wheelchair and was able to get a .5" group at 50yards at dusk. I am looking forward to trying it out. The handloads had issues feeding, previously fired in a M305 and fullsized.
 
Rfb accuracy

Just got back from the range - strong gusty cross winds ( I tried to shoot between Gods humongous farts ). To windy for 200 yds.

I used a Trijicon 1-4x cqb scope.

3 rd. groups with Privi Partisan at a 100 were under an inch.

5 rd. groups were under 2 inch's with 2 or 3 touching and the rest opening up ( I didnt wait for the barrel to cool between each shot and the barrel was only warm not hot ).

Winchester 155 gr. soft points looked promising but I didnt have enough rds. to be conclusive.

Mil surp (FNM) was 3 inch's for 5 rd. groups but as I kept going to 20 rds. the groups were stringing vertically 3inches wide by 6 tall. I have a theory about the vertical stringing (its caused by the shooter not a heated barrel - I think -but I will wait to prove it before I say more {Its happened to me in the past with accurized M 14's.}).

The rifle was a ##### to shoot off the Bald Eagle rest and a rear monopod on a thin sand bag.
When I extend the rifle for bench stability and my booger picken finger isnt numb from the cold , I KNOW the groups will be tighter.

So far - for a semi auto .308 the accuracy is just fine. :D

Cant wait for the warmer weather with my 36x scope ! w:h:

I spoke with a Keltec service rep this morning to get some answers for the RFB's accuracy, he asked the engineers and had to call me back. He gathered the following answers for me:

- 1.5" @ 100m/yd is the standard RFB group, it is a battle rifle not a sniper rifle(it's intended use is QCB 100m or closer)
- the RFB is optimized for 168 to 175gr bullets
- factory tests were conducted with Federal Match Gold
- can become more accurate with more rounds put through the gun (200 or more), groups have been seen to tighten up 1/4" to 1/2"(engineers observations through word of mouth)
- some RFB's are more accurate than others
- is the rail tight ? might need loctite
- gas at lowest setting ?
- close sight aperture makes it difficult to bench shoot(referring to the RFB being so small)


I also asked about the longer barrelled version and if it would be possible to just have the RFB re-barrelled:

- 24"/32" barrels are not being fully produced yet(need a bigger machine)
- your RFB can be sent to the factory to be re-barrelled or an armorers kit can be purchased in addition to the longer barrel and then be taken to your local gunsmith


Friendly staff and great customer service.

In my opinion the RFB is still the ###iest little deer rifle (meat catching device) out there. :D

(Sorry for the hijack...) I got my RFB today and what a beauty it is! I can't wait to hit the range with this and cutting loose. The RFB feels very solid and well-designed. If Kel-Tec ever wanted to try marketing the RFB off to the military I don't see them having a problem. Now all I have to wait for are the bigger magazines and my baby will be complete. Massive thanks to Wanstalls and Vault for bringing this sweet, sweet piece of firearm into my grubby hands. And I love the Wanstalls tactical mouse pad that was included!

Here's what my RFB would look like with my Millet DMS-1 scope mounted on super ninja invisible scope rings.

Also a question (well two), does anyone know of a place to thread the barrel in Ontario and where I can get a Noveske flash suppressor that would fit on said threading? I looked at Dlask and they only have it for 1/2 X 28 threads.

(Resume regular scheduled programming)

Joe at dlask has already threaded a RFB and has a muzzle break and flash suppressor to fit it..
When my RFB gets in, it will be going straight to him for the same reason.

Highly recommend Dlask...it was my RFB that he threaded and the work was fantastic. I chose 5/8x24 as it seems most 30cal after market FH's and breaks are that thread pattern.
 
Kind of an off topic but related... So the canadian RFBs do not have a break or flash hider. What im wondering is the feasability of threading the barrel in say the same thread as the CZ 858 as there are a lot of options for thread on breaks. My understanding is that the 7.62x39 m43 round is actually about .3105-.315 versus the 7.62x51 is .308. Anything im missing in this? Suggestions?
