I've gotten my hands on the closed top ARC mausingfield, it is made for a detachable mag, and its serial is 00005. I've attached a few pictures to show the ejection port. Also sorry for my potato quality phone. Best I could do today. Build is settled on .300 prc and will order ammo from Hornady. Hopefully more manufacturers catch on and make some good quality like hornady as I dont reload right now.
New ARC Mausingfield
- Thread starter Nightlybane
- Start date
I'm pretty sure it's the newer version as this is the only other thing I found on the website about the closed top:
- Closed Top Version
- Does not support BDL bottom metal.
- Rem 700 style mag well accepts AICS style mags (Long action accepts CIP length magazines).
Also found this, 1.125” x 20 UN 2B for threads. Compatible with Savage Long Shank Barrels.
I would double check that:
“Mausingfield actions with serial numbers of M5A4-00025 and higher and all M7's use a 1-1/16” x 20 UN 2B barrel thread, making them compatible with commercially available Savage small shank barrels and locknuts.”
What’s your model number, which is the M#A# bit before the serial number?
Did you just buy this direct from ARC or did you buy it from someone off the Hide? Everything made in the last ~8 years - including the closed top mausingfields for DBM only - is small shank.
Edit: the reason I care is because I don’t want you to waste a few hundred bucks getting the wrong barrel made.
Actually what possibly cool is that appears to be one of if not the first Mausingfield available to the public.
Bought it straight from ARC. They just released this model as far as I know. M7-TLR-D-00005 is mine. I talked to Jason and he asked if I wanted the closed top like the older ones and if we had enough people thatd I'd get the closed top instead of open top.
If yours is a M7 it’s new production and small shank.
Show a pic of the bolt release, the new style is obvious.
Damn. I was hoping for a large shank because of that extra 2 inches from proof research.
I'm going to use SWVAguns to build my rifle once I get all the parts I believe since he has worked on mausingfields before unless someone can point me to someone better
Hey man, I just checked on this paperwork and it says this : Serial number or notes: M7-TLR-D-00005 BUT THEN down below it shows : Product: M7-TLR-535-20 Mausingfield Bolt Action(Closed top,detachable mag, Right, 20 MOA, 5.8 MRAD long [3.78" mag length] .535 [i.e. 300 win mag]) yet the action itself states the top TLR-D number and not the other. I'm guessing the other is the product number?
Loads of reasons why this isn’t one of the first ones they made; the early ones:
-were in the white; not nitrided
-had the hookah pipe bolt knob with exposed screw head
-had a different bolt stop
-were in the white; not nitrided

Ah. All M7s. Gotcha. I overlooked that. Wish they had it laid out differently on the site.
Agreed. Early ones looked shiny. I ordered off their site so I knew I'd get the M7
The second number TLR-535-20 just means it was assembled with a .535 Mag bolt face & a 20moa rail. Both those can be changed so they aren't stamped on the receiver.
LRI (Long Rifles Inc) has probably barreled more Mausingfields then anyone. This is were I'll be sending my M7Damn. I was hoping for a large shank because of that extra 2 inches from proof research.
He tunes the extractor so that control round feed works properly. Supposedly the new M7 extractors have been improved by ARC and don't require much if anything to work properly. Video below shows how control round should feed if set up correctly.
As of right now as it sits lift is stiff right now, and the throw is smooth as shit. but until I get the barrel, stock and trigger, I won't know for sure on the lift. I'm sure itll be easier on a stock.

It will be okay! By time I get back I'll have enough for the stock, barrel, and trigger! Next I'll save for the scope and rings. I'm hoping itll be complete in 2021.
I bet you wish you couldSend it to me, I’ll break it in for ya.
