We have one right hand Tikka T3 2 stage trigger going spare. Brand new, drop in upgrade for the standard single stage unit. As fitted to the Tac A1 etc. £200 plus £10 delivery.

Due to popular demand we will be reintroducing our Same-day Saturday Service as of Saturday the 3rd of February. There will be limited slots available each Saturday and require booking in advance. Services available for the same-day slots include barrel shortening/threading, barrel crowning, tactical bolt handle conversions, bolt fluting, Hornady OAL gauge modified cases, trigger supply and fit or trigger tuning, minor repairs and adjustments etc. Please contact us for any questions or bookings. Thanks JR Firearms.

They basically are Sassen/border barrels. They just have new owners and a new name 👍🏻. It’s good to see they will continue and i’m sure they will be better than before.

Thank you both for the kind words.

I’ve straightened one before and it was fine. Worth trying, if it fails down the line then you are no worse of and need to replace it.

Gunwerks GRB action, R/H S/A .308 BF, a very affordable custom action with some good features. Cone bolt face, strong extractor, pinned recoil lug, field strippable firing pin, Borden bumps on the bolt, 20MOA bases and so on. PM for details.

Ditto what Ronin said.

Yes it’s fine. To be fair Tikka/Sako barrels are more stable but i’ve seen alot of stress relief issues with Remingtons. The bore can open up at the muzzle once it is turned down and threaded.

In my experience hammer forged barrels are the ones more prone to distortion/warping, i had it happen during testing on a scrap Rem barrel. It can even be seen due to threading if you look for it. It all comes down to how much residual stress is in the barrel after manufacture/stress relieving. When you machine the barrel the stresses can release and that is what causes the problem. Hammer forged barrels due to how they are made tend to have more stress in them. Where as button rifled barrels if properly stressed relieved have minimal residual stress. And cut rifled should have virtually none. Plenty of people flute factory barrels and it’s fine. But also there is a good chance it will cause problems. So personally i won’t risk wrecking a customers rifle. Normally shortening the barrel is more effective at weight reduction and improved handling.

Thanks Andy. I would not advise fluting a factory barrel (i won’t do them). You risk ruining the barrel because it can warp, or the bore can distort due to stress relieving during machining.

Thank you. Machining is fun until it goes wrong 🤣.

Me too, it’s a bit of an addiction 🤣

Finally got around to setting up and trying the true bore alignment system on the Haas CNC lathe. First job was a couple Remington 700’s that needed truing.

👌🏻

We get referred to as gun plumbers, so it’s only right to use the pipe wrench 🤣

Everything is accessible for a price 🤣😅 I more use to using gantry CMM’s, so this is a little weird to use. But to have similar accuracy of a ganty CMM but with the flexibility of the arms is pretty cool.

I avoid using heat, there is no need for it with these. And it avoids any damage to the bluing or heat treatment. The main issue is gripping the barrel well enough in a normal barrel vice, the stilsons take care of this.

Yes i normally part them off too, especially blued howas. But both lathes were tied up with jobs, so i just had to get medieval on it 🤣 This had a nice mix of loctite, rust and carbon.

A couple more new toys added to the workshop. The main one being a Faro CMM arm. This allows precise measuring of parts for QC or reverse engineering. Such as copying the outline of this Sako 85. We then convert the information in to a CAD model for inletting/machining. This is handy for opening up inlets for bedding etc.

Sometimes they need a little persuasion.

A recent rifle build using a lovely Impact precision action.

It’s a Manners T5.

It can cater for all popular calibres 🤣

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