JR FIREARMS

We have added a new machine to the workshop. A laser marking machine/engraver. 

No such thing as too much Carbon fibre. A recent build we put together. A Terminus Kratos lite, Proof research carbon barrel, Gunwerks carbon stock, and a host of other nice bits like the trigger, bottom metal etc. And a 3 port muzzle brake courtesy of Dave at Valkyrie, which we blended in to the barrel profile. 

I personally never use to be keen on it and preferred straight flutes. But i’ve come to really like it. 

A HS Precision stock inletted for a Tier one AICS bottom metal. 

Some helical barrel fluting on this Rem varmint profile barrel.

Hi JR. what would be an approx turnaround time be at the moment for a rebarrel/cerakote.?

Hi,

It’s hard to say at the minute with all the delays. For me barrels are roughly taking 4-6 weeks to arrive, and proof about the same. My last batch were 6 1/2 weeks at proof. Then my time to get the work done which is a couple weeks or so. 

Thank you. 
 

For anyone wondering the V bull target was a Rem 700 .308 Win/Bisley i rebarreled, using GGG 175gr factory ammo at 1000 yards. 

A few pictures that may be of interest to people, just a few rifles and jobs we recently done. 

Some heavy helical fluting from the weekend for a couple competition rifles.

Out of interest what would one of your rifles cost?

Other than winning the lottery I know I'd never be able to afford one but I can dream.

 

 

I had better start saving then if they are less that the current AI offering of about £4300 then I might just do it by the time I retire

Sorry for the late reply, i didn’t see your post. Prices vary greatly depending on specification such as semi custom or full custom. Feel Free to message me any questions. 

Currently it is bare aluminium that can be anodised, but stainless can also be used. 

The finished article. 

Imitation is the sincerest form of flattery 😬

I’ve not had much time for projects recently due to work load, but here’s a little project i’ve been working on here and there.

A low profile picatinny rail for the Sako 85 that is attached via M4 cap head screws. It requires thread milling the action to accept the screws. It’s not a new idea as Neil McKillop has been doing this for a while, i just fancied having a go for my own rifle and maybe the odd customer. 
 

It’s much more versatile than the optilocks and negates any alignment issues that some suffer with. It also gives the option of making a 20 MOA version for longer ranges. 

Yeah it’s a neat little holder, but getting the toolpost and holder all correctly trammed is a bit of a pain. Otherwise the reamer can be pointing quite a way off, which is going to end badly lol. 
 

I’m sure like yourself we have our established ways and processes to chamber that just work and comfortable with. So it will be a bit of a learning curve, but i do all other jobs on the CNC now so thought it would be a fun project to get it chambering. Unless using carbide reamers there will be no real gains other than it’s cool 🤣

I’ve got a good take off barrel and bought a reamer specifically for testing. Good or bad i’ll post the results hopefully in the comming weeks. 

I believe both have them have moved away from rigid reaming due to too many variables and fluctuations. This is based off of their own comments on forums etc. 

Hi Andy,

Chambering off the tool post does bring it’s own issues, such as repeatability and lack of feel. So work holding and feeds & speeds are cruicial. A floating holder is a must for the toolpost, my one pictured is an axial and radial floating holder. It just happens to have a built in ER collet. As for the barrel setup, this is exactly the same as on a manual lathe. 
 

I’ve not had chance to run it yet as it’s a side proiect, i’ve been gathering tools as well as plumbng the flush system. Once i get it running i’ll post up the results, wish me luck 🥴

Looking very good.  Is the blue 'spider' carrier something you've manufactured?

The action truing jig, yes i made it myself a good few years back. 

There has also been some new tooling and equipment installed. As well as making a new reamer flush system For the Haas to play at CNC chambering. 

I’ve been a bit busy of late and forget to take pics or post about it. So here are a few pics of odd jobs for those that may find it interesting.

 Would it be possible to correct misaligned holes using this method ?

Yes it’s an ideal way of solving that problem. The boring of the hole and thread milling mean the old thread will not influence the new ones, which is what can happen when using the traditional method of drilling and tapping, as the drill and tap will want to follow the old thread.
