Bottom Metal for Coup de Grace Build

[Chipster697]

I am assembling a 7mm-08 rifle for hunting and some range play. Do not need or want a barricade stop. Ideally I want to be able to have a 3 or 4-round flush magazine for the woods but also be able to have 10-round mags for the range.

ARC likes AW mags but I haven’t been able to find anything other than a 10-round magazine. Am I missing something?

Two options I’ve found are the Hawkins Hunter DBM and the Greyboe Hunter. Both are M5 inlet and have non-tactical magazine releases. Greyboe says theirs accepts any AICS mags, 3, 5 or 10-round but a search here didn’t turn up anything on this bottom metal. Hawkins indicates theirs accepts AICS magazines but they also sell a proprietary 4-round, flush fit magazine for this DBM. Does anyone know if you can run both the proprietary 4-round and AICS mags without diddling with the magazine latch?

I use the Hawkins Hunter DBM with both aics mags and the proprietary hunter mag without an issue in my 6.5 Creedmoor rifle.

MDT Precision bottom metal. Once you have adjustable mag latch, you wont want to go back. Eliminates all feeding issues with mag height in various chassis/stocks.

I just put one on my last rifle and can’t believe much difference it makes.

In what way?

Also, I just got off the phone with someone at Hawkins who cited all kinds of fitment issues with the CDG receiver. Surprises me because ARC recommends their bottom metal. I did see a recent thread about problems feeding 7mm-08 specifically in their proprietary Hunter magazines.

I could get the mag to fit perfectly and feeding was perfect and lockup with mag was positive. The mag latch is screw adjustable to make it easy to set just right.

If you don’t mind the barricade stop, I would absolutely recommend the MDT bottom metal instead, and I own both. The only reason is they have the adjustable mag latch, which is necessary to get optimal feeding for most (not all) rifles. I used it for a terminus build recently, knowing it was a 3 lug action and was able to easily adjust the latch to get the mag feeding smooth as silk.

BUT, as I said in my original post, the Hawkins has worked perfectly for me.

Oh! I did not catch the lack of an adjustable mag latch in the Hunter DBM. Very good to know.

Is yours a CDG receiver or something else?

MDT gets my vote.

Mine is a terminus action I used the MDT on.

I use the hawkins mag and aiaw mags with my CDG and Mack Bros bottom metal.

Aics mags need a shorter mag latch for me. I would try the flush MDT poly 3 round but my guess is they would need the shorter latch too.

Did you encounter any “fitment”issues with your Mack bros when installing into your stock? Hawkins let me know that it would require custom inletting for their hunter dbm to work properly with cdg. I am running with 300 wsm so maybe that complicates things. What caliber(s) are you running through CDG?

The adjustable mag latch is the answer, but it's only available on the MDT bottom metal with the barricade stop, not the hunter.

I tried 10, 5, and 3-round magazines. The three-round, plastic MDT mag was the best, but the bolt dragged on them all.

Off to try Hawkins.

Bottom metal dropped right in on a manners.

The Hawkins hunter mag was really tight to seat fully so I did file the mag catch on back of mag for more positive and reliable mag seating.

I am running 6.5prc right now in my SA CDG. Feeds reliably for me.

You want something with an adjustable mag latch to utilize aw mags, as that's what the Cous is designed around. Hawkins M5 with the long latch, filed down for perfect fit, or the MDT with the adjustable latch.
