Why look at Howa, Remington or Ruger when you could have one of these in 300 BLK, Kimber Adirondack 300BLK...nice, light and short.

The Grendel only needs 14.5" of barrel to get its maximum velocity from a 123gr bullet. Use BM 8208 and it can get you 2500fps no drama.
I load mine to 2450fps and have shot it to 500m with great accuracy. It holds about the same energy as a 100gr .243 win at that range.
Personally I wouldnt go any shorter than that with the Grendel. You mention you want the suppressor to come all the way back to the stock,
most popular over barrel suppressors are 110 to 120mm rearward of the threads shoulder so 14-15" barrels achieve this in most stocks.
This is my 14.5" barrelled Grendel in a std stock and a chassis
If you intend to go as short as 11-12" you will have to use a muzzle can instead which will give you the same over all length when fitted as a 14-15" barrel fitted with an overbarrel suppressor.
for this reason alone you are better to keep with the 14-15" which will give you more velocity from any cartridge you decide on without effecting your over all suppressed length.
As an example heres my 7.62x39 15.5" barrel fitted with a compact hardy overbarrel suppressor next to a 13" long .22 Grendel barrel fitted wit a DPT can with the std 5 baffles. They are the same OAL when fitted to the rifle.
The howa 300BLK is a ‘heavy barrel’ but because of that larger bore diameter it comes in at the same weight of the 223 mini lightweight.
So if you shorten it it will be pretty compact
Warm Barrels!
I rebarreled a 223 montana to get something similar to the adarondack 300blk
they are great and crazy light mine has a 12.5inch Trueflight barrel
Iv had to lighten the trigger a heap as i noticed that with the trigger squeeze it was pulling me off target
when i want more weight i swap the oceania defence alpine supp for a DPT with a crazy amount of baffles added to it
quiets it down really nicely
the internal magazine is a bit more of a chore in 300blk as im using it all the time almost every day, it never annoys me with my 243 montanas
Id really like it to be mag fed but there isnt a simple solution for that
the ruger american 300blk is what my mate runs and it has the advantage of ar15 mags, shoots well ect they are a good cheep option
Hard to say as I just tick away at them when I get a couple of hours spare in the evenings. If I had a good crack at one Id say about 25-30 hours from billet to duracoat.
Most of the time is in the machine set up.
The .30BR took a bit longer because I rebarreled it from .22-250 Rem and had to mod the trigger to work in the chassis. I photographed the whole process but havent had time to write up a build thread. Ill see if the owner can share some more pics etc in a new thread.
That upper was sold on here and I got to play with it (2018) from the third owner, pretty cool bit of kit had a custom gas length with a grub screw from memory with a fancy trueflite barrel and perfectly fitting gunworks suppressor?
It sure was nice to shoot, very accurate.
With the MDT LSS specifically you can put something like a AFG Mlok grip on them if you want a grip and use a rubber pistol grip, but yeah each to their own, the body is still ali (cold).
But if you are shortening it back to 10 - 12" it will be fairly light though won't it? and possibly a little more accurate if it is a heavy barrel?
Also see @300_BLK comments on the heavy barrel weighing the same as the lightweight.
RE: non stainless - if you got the barrel cerakoted which wouldn't cost too much should be sweet as long as you clean it ?
