I have a new AX short action chassis set to be delivered on Wednesday, but I have a few questions. I'm dropping in a Rem 700 with a Timney 517 and 24" Krieger barrel in MTU profile. Ideally, I'd have my Atlas bipod as far forward as possible, but with the 13" handguard, I'm not sure exactly where it'll end up in relation to the muzzle. For those of you running a 24" or longer barrel, are you satisfied with where your bipod sits? If not, have you swapped over to the 16" forend, or is the 16" too long? It's a pricey replacement at around $350, but if it's worth it I'll consider it. Also, will the Timney drop in? I know on the old AICS, you either had to trim the Timney safety pin or cut into the chassis, so I'm wondering if that is still necessary. Thanks in advance y'all!
Using an AX chassis? Come on in...

I have two AX chassis and with the standard 13" forend tube you're going to be just fine running the bipod out towards the end, in fact I brought my bipods back a little bit on the tube so that I could reach the bipod easier while in the prone. For me the 16" forend would be unnecessarily long. I have Timney 510's on both of my rifles and they drop in just fine, there's plenty of clearance all the way around.
Many thanks! In another thread, someone posted that they needed to run higher rings than normal because even with the cheekrest at its lowest setting, the scope still sat lower than the comb height. Was that your experience as well? Also, as I understand it, standard AICS mags will work fine, but might have a bit of play in the lockup?
It's fine running standard AICS mags in the chassis, I haven't had one fall out yet. It's a given that you need to run higher rings that you would normally run on a standard AICS given the forend tube. For 30mm optics with a 50mm objective the NF A108 1.265" is just about perfect without having to make any adjustments to the cheekpiece. This is with a first generation AX AICS that uses a standard AICS cheek piece. On my 2014 AX AICS I'm using NF 34mm A226 1.375" rings and for both my ATACR 5-25 F1 and the Bushnell ERS that I used to have the elevation is perfect, it's all pretty comfy.
A note about scope ring height on the 2014 AX: I am running a 2014 AX and my scope has a 56mm objective (it is sitting on a Defiance action with an integral 30MOA rail). I started with 1.375 rings and they provided more than enough clearance above the rail. However, the 1.375 rings did not raise the scope enough for comfortable alignment with the eyepiece. The reason is that the cheekpiece on the chassis is very high, even on its lowest setting. I ended up using 1.5 rings and that solved the problem. I would recommend you check that you can comfortably get behind the eyepiece if you want to run lower than 1.5 rings.
Do you have a big head? I'm running a standard Remington 700 with Badger 30 MOA base, Nighforce 5-25X56 F1, NF 1.375" rings and I have to raise the cheek piece up to get good alignment with that. With the cheekpiece all the way down the top of the cheek piece is about 1 7/8" below centerline of the tube. Everyone is going to have their adjustments a little bit different but the 1.375" rings are a good place to start and chances are it's going to work for a majority of the people out there running 34mm scopes with 50mm or 56mm objectives.
Guys, I appreciate all the responses! I checked and my rings are Seekins 1.25", so I think I'll pick up yet another set of rings (You'd think after all these years, I'd just learn to keep several sets on hand, but NOOOOO.....)
Hmm, I was planning on using a CE. Did anyone else have to trim on theirs? I do not have to trim with the triggertech.
My girlfriend tells me it's average. Yeah I'm not sure why I had this problem. I have never had to run 1.5s on any other platform. Other than this quirk I love the AX.
