View Full Version : Magpul 700 feed issue
I am having a bit of a feeding issue with my .308 Magpul stock and DBM using Pmag 5's (two separate mags). The nose of the top round in the magazine, if not fully seated rearward in the mag, will get caught under the lip of the chamber (under the feed ramp) and cause a FTFeed. I have to remove the magazine, seat the round rearward, reinsert, and try again. Has anyone else had this issue? It occurs more often with longer (higher grain) bullets/OAL, naturally. I know the simple answer will be an obvious "Just fully insert the rounds into the magazine, dumb dumb" but often I thought I was doing so. I've not had this issue with the factory internal magazine. Maybe I just need to pay more attention to it. Here are some pics:

can the feed ramp be recut?
just take the mag after every time you load it and smack the rear side of it against you hand a few times. this will get all the rounds seated to the rear.

It seems surprising that this would be required but that does sound like a viable solution.

I'm the guy that gets a chuckle when I see others doing this to all their magazines unnecessarily, haha. I don't want to be THAT GUY! :)
Have you tried shining a flashlight down the front of the magazine to see if any bullet tips are touching the front of the magazine?

I just looked. The rest of the rounds in the magazine are properly holding all the way to the rear.
This is interesting. What ammunition and OAL are you using? We'd like to see if we can replicate it.

Federal Gold MM 168, Hornady Match 168 and 178, PPU Match 175. I can take some measurements of them but I was using only factory ammunition.
Measurements of some of the ammunition on my use list: 2.785", 2.804", 2.800" (no particular order)
Here is a picture of the lip where the top round is catching. I admittedly cleaned up the sharp corner a little to minimize the issue I was having and this helped a lot but I still get a few that will catch here.

Thank you. The PMAG 5 AC will accommodate up to a 2.86" OAL so it doesn't sound like it's an ammunition issue. How are you inserting the magazine into the rifle? Are you indexing the front of the magazine and then rocking the rear of the mag into the rear of the mag well? If that is the case it sounds like the rear of the cartridge is making contact with the magazine release ramp and pushing the round forward into the lower portion of the ramp as you have shown in the photo. Try inserting the magazine by indexing on either the left or right of the magazine well and then rocking it into place, this will allow the top round to stay in the same position and not make contact with the feed ramp lip on the receiver. Please let me know if this helps.
Okay, I will try that out.
Additionally, I found there to be a significant amount of axial play of the barrel/receiver when installed in the stock before the action bolts are installed/tightened. The action should be fully seated rearward in the stock so the recoil lug makes full contact against the bedding block (I'm aware you know all this. Just painting the picture). With the action all the way to the rear, the feed ramp/lip protrudes the most, making the feed situation I have worse. I found if I slide the action forward, the feed ramp/lip moves most of the way out of the way and my issue is alleviated. This is not a solution as the recoil lug is no longer properly seated.

Well would you look at that! I definitely was indexing the front of the magazine and then inserting it and I can watch the magazine latch push the top round forward. There are even brass marks on my latch. If I lead with the rear or either side (or even just inserting it straight) the issue does not exist. This shouldn't be too hard to get used to, I'm not much of an AK guy ;) Thank you for your help!
That's awesome. I'm glad it worked out for you.
I appreciate the fact that a Magpul representative quickly interacted with the OP and worked out the issue. This speaks volumes about a company and their desire to manufacture a quality product.

This parallels my thoughts.

I very impressed with the Hunter 700. The ability to customize the ergonomics to suit a persons individuals requirements is awesome. Especially at this price point. I just got a set of risers today and raised the comb with the .50 inch along with adding an additional spacer to lengthen the LOP to 14 inches. Now the fit is even better. I'm looking forward to bettering my first outing with it this weekend. This is new AAC-SD handload 168 HPBT backed with RL15 powder using Lapua brass, a little over .4 MOA 5 shots at 100 yards. Magpul CS is superb. I've called them a few times with minor issues and questions and they have always been nothing but friendly and helpful. I've only one minor complaint with Hunter 700 which I noticed first time I set it up. The screw that locks down the LOP spacers/comb allen head bore stripped first time I tried to remove it. I can use a flat blade but would like to get a replacement. I would like to avoid having to carry a large blade screwdriver in my kit. OH, second minor complaint.... that the 10 round mags are not here yet! :)

Thats what I was thinking. I just talked a buddy into the Hunter for his new 700 and he couldn't be happier! Its the customer service that sells me every time!
I'm waiting on the Long action version. It'll have a provision for box magazine? No need to bed the stock?

While your question may get answered here, there is a thread on Magpul R700 stock discussions here:

Thanks for the link. So, you're all good with the stock and mag now?

While I haven't shot it since discovering my magazine issue, I've done lots of various loading exercises at home and everything seems to be working well. I will report back once I bring it back to the range again for live testing.
