Thread: Remington 700 Bullpup chassis build

Right... Ive had quite a few messages and questions in regards to my Bullpup stock on my 6.5 Creedmoor (featured in my "6.5 Creedmoor load development thread") and promised a few of you some more details.





Love them or hate them, bullpups have always been my thing. Moving the action as far rearward as possible and reducing the overall balance and length is one benefit but there are many others.

This build started as an idea about 15 years ago and just never got the tool time.. Ive had a piece of laminate sitting in the racks for just as long, just waiting its turn.
The design evolved over the years and even more once it was on my workbench but my original drawings were for my Remington 788 in .338 Whisper I had at the time.

When I recently picked up my new Rem 700 in 6.5 Creedmoor with its unwieldy suppressed 24" barrel I got motivated to have a crack at building the bullpup stock for it.

Now.. rather than a big long winded build thread Im just going to post a bunch of pics I took on my phone as I progressed. If you have any questions Ill try answer them. Sorry some of the pics are pretty crap and I didnt document everything but regardless, there's a few to look at.

Inletting:








Additional shaping and pre-fitting parts:






Forward trigger block and linkage:
Triggers are almost always the downfall and questionable parts on bullpups with the inevitable linkage set ups, but Im very happy with the way this one operates.
Ive built quite a few PCPs in bullpup stocks so learned a bit about trigger linkage angles etc along the way that got implemented on this build. The trigger is fully adjustable in every way you could think. While it still has a std Xmark Remington trigger I have worked slightly so that it had a 2.5lbs crisp break but adding the linkage actually adds leverage making the trigger very very light if you wanted to set it that way. I added a slotted trigger shoe on the stainless steel linkage bar that can be set up as a "first stage" of trigger movement which gave it a nice two stage feel once tuned.

The forward trigger block is also fully adjustable for weight, position in trigger guard, first stage pull length and over travel.
I have it set with about a 2mm first stage light and smooth take up which comes to a noticeable stop and then a 1.5lbs crisp break. I left the factory Remington safety catch in place and adjusted the bedding block design to work around it.





















Accuracy international pattern mag release:











More prefits, barrel shortened to 20" and rethreaded and cutting up AR15 accessories to work with the chassis:











Gelcoat, filling and prepping for finishing with a spray suede texture coating to look softer more like a synthetic stock and then several coats of Duracoat matt black:













Assembling completed chassis:







I dont really have any good pics of it in its current state as I have made a few changes and have a few more to make but will add them here once done.
The butt pad is just crappy plastic but I imported a few of the good thick rubber ones from XLR chassis USA, they are not quite as tall so when I get time in the workshop Ill make an adjustable mounting plate to suit and ditch the shitty bulky plastic one. I will shorten the LOP a bit too.



Here it is along side my Rem 700P LTR for length comparison which also has a 20" barrel.
The 6.5 pup is currently 800mm long to the muzzle but will drop to 780mm with the new rubber but pad.
