GRS Rear Bag Riders

We are periodically asked to make rear bag riders for various rifles and it is at this point we have to take a view on is it going to be a ‘One off’ or is it worth productionising and making a run of parts.  The latest example of this is a rear bag rider for the GRS rifle stocks.

Now I am a huge fan of these stocks, they are well made, look good and most importantly fit the actions they are designed for really well. About the only thing I ever do is an occasional pillar bedding job and, personally, would not worry about a full bedding job because in my view the potential improvement of accuracy is not worth the outlay. Just my view…

One of the things that aids long distance accuracy is the tracking of the rifle on the rear bag and if the rifle stock you have chosen is not designed to track on a bag you have a problem. It is fair to say rear bag tracking is not the be all and end all of rifle accuracy, however it does have a significant impact on the ability of some shooters. Hence we build rear bag riders for rifles that are not ideally suited to such techniques otherwise and examples include the Accuracy International chassis systems and Tikka T3x Tac A1 and now the GRS.

OK, the first question is what does it fit, well certainly the following:

GRS Berserk
GRS Hunter
GRS Hybrid
GRS X-Eater
GRS Sporter


I suspect the rider will fit other GRS chassis, however I cannot be sure about the rest of the range until I get my hands on examples to test with.

The GRS Rear Bag Riders come as a black anodised plate with a self colour aluminium tube and are supplied with three longer A4 stainless screws to enable fitting.

To attach the rear bag rider remove the existing adjustable butt section from the rifle chassis. Remove the small self tapping screws holding the butt pad in place, then remove the three screws holding the three pillars in place, these screws will have been glued in place so you may need to carefully grip the pillars in a vice or similar. With the pillars removed place the rider plate in front of the original plate and hold it in place with the longer screws passed through from the back of the original plate. Nip the three screws up tight, I do not use any Loctite however you can do so if you wish, now fit the butt pad using the original screws and re-attach the rear butt section to the chassis. Finally, attach the 18,5mm tube to the hanger using the supplied M8 A4 stainless screw and you are good to go. Fitting probably takes around 10 minutes if you are cautious and the process can be reversed at any point if needed.

Rear Bag Riders for the Tikka T3 Tac A1

We have just finished a run of these in standard and lightweight options.

As ever the plate is 6082 vapour honed black anodised aluminium and this one has the ‘competition’ carbon fibre tube so overall weight is under 150 grams, whereas the standard is closer to 200 grams.


Do bear in mind the carbon tube is not as robust as the standard aluminium tubed version, having said that they seem to stand up to a lot of abuse, I just would not jump up and down on one of them!

We also build the RBR for all Accuracy International models including the competition special at 99 grams. Also covered are the Sako TRG 21/22 & 41/42 models plus a variety of standard T3 models.

Also, due back from the anodisers very shortly are rear bag rider brackets for the GRS range of rifle stocks in both standard and light weight versions which look really good when fitted to a GRS stocked rifle.

Lightweight Rear Bag Riders

Despite my bitter dislike of anything carbon fibre related due to the fibres that seem to get everywhere I actually enjoyed making this, a rear bag rider for an Accuracy International that had to be light. This is a mix of carbon fibre and 6082T6 and rolled in at 95 grams so it ticks the box and I think it looks rather smart as well, or will do when I have wiped my grubby prints off it. Something to remember with our light weight rear bag riders is by nature they are not as robust as the normal 150 gram versions as a third of the weight has been shed however as long as they are not seriously abused they seem to go on for ever and I know for a fact that all of the ones I have built to date are still out there on rifles and in constant use.

There is a 75 gram version however I only do these to special order and they are not as pretty

I guess I had better get back to work as it feels like we are knee deep in rifle and shotgun work right now. Roll on getting the dogs out time when it is a bit cooler. I will make an effort to update you all on our recent projects over the weekend.

As an aside the workshop doors are open and I just looked up and spotted a male House Sparrow perched on the door handle of our Defender, how odd…

Schmidt Rubin K31 Bore Guides

It is nigh on a month since I posted to my Journal which should tell you something as I am usually very quiet when we are running flat out as we tend to just focus on what we need to get done.

The good news is we have passed a couple of mile stones project wise and can (In theory) get back to normality and on the subject of normality here is a cleaning rod guide or bore guide depending on your side of the Atlantic for the Schmidt Rubin K31, I have built for other SR’s however never the K31 for some unknown reason so here it is and it may even be in our e Commerce shop by now, if not just email the Viking and tell her you want one and she will confirm our anticipated delivery date. Right now bespoke bore guides are going out within a couple of weeks and stock bore guides such as the more common Sako, Tikka and Remington items same day and we usually have a few Accuracy International variants built and ready to go for everything from the AW to the AXMC.

If in doubt just drop us an email or call the workshop.

Finally, why am I calling the Bore Guides as well as Cleaning Rod Guides? Well I have always referred to them as the latter however some confusion has cropped in to the two names and if indeed they are separate products and the answer is nope, a Bore Guide is a Cleaning Rod Guide the only difference is where you live 🙂

The things I do…

I have been finishing off 5P comparator sets today, this means they are bored and finished with just the polishing left for me to do which was this afternoon’s task.

Now those of you that have experience of polishing small parts will appreciate just how awkward this job is. Despite wearing grippy gloves, if I am lucky I will finish the day with polished thumbs and forefingers and if I am unlucky the comparator sections are going to pick up and be launched into space (Pingdammit) with me wondering just what I did to manage to lose my grip on the part…

On a plus side the weather has improved, the majority of the snow has disappeared other than the remains of the drifts in the shade and on the high ground around here and right now it is showing 14C outside which is positively summer to us after the last few weeks and it was the Viking who pointed out we have had a remarkably cold 5 months in comparison to what have been used to in the past.

Tomorrow is Mother’s Day so that is where we are going which is a nice cross country 65 mile drive without a hint of motorway or proper dual carriageway and if the weather holds out is should be an excellent day’s outing.

Monday I have some guides to finish and polish and we are then back on rifle and shotgun work for a couple of weeks at least which is always good. I have some chambering to do including a .308 Winchester, a .223 Remington, a 6,5×47 Lapua and a couple of Wildcats, one for a customer and one for myself which I rather hope I can slide in. Nothing serious however it will all be done on the new machine which will be interesting. I think I have everything covered however I suspect I will end up making some minor tooling changes along the way.

There is also some LBR (Long Barrelled Revolver) plus some black powder stuff to look at so a really diverse range of things, some of which will surely merit a comment or two on this journal.

Right, well it is warm outside and a Lurcher is hurtling around the gallery upstairs so it is probably time to get him out for some exercise along with the Labrador who has looked absolutely pathetic whenever I have walked past him which is his way of saying he wants to get out as well  🙂
