I got to shoot the Stag again before the snow closed in. This is a Stag A5 , 16 inch barrel, 1 in 10 twist, SPEC II chamber. A2 Butt stock, Tubbs Flat spring and a Leupold 6x 42mm Scope.

When fired before feed ramp mod to an M4 style, it would fail to feed and deform enough rounds thaat it would throw a few out of the group.

After the Feed Ramp modification it does not hang up while feeding and the groups are much better since the bullets are not being deformed.

You can see from a standard non-M4 style feed ramp area how the larger 6.8 SPC cartridge could hang up or deform.

Compared to the new modified ramps:

Now the Stag loads them smooth as butter.

Nice. I have to do this mod soon. You were aiming for that square right? :wink:

Actually the scope is zeroed for 110 grain Nosler Accubonds and I was aiming for the diamond which is out of the photo. This rifle changes impact point quite a bit with different bullets. It even changes impact point by a few inches just by changing the primers.....

Float Pilot, if the squares on your target are one inch squares, the best I can tell is your four shot group is .337 MOA and with the 5th shot still an acceptable group of .641 MOA. Not bad my friend. I think we found someone who can outshoot his rifle

Nice work!
Its almost hard to believe that such a seemingly small thing can make such a huge difference.

 

[Eliminator]

Nicely done Float! Fantastic improvement.


Not to hijack, but I noticed you are in Alaska. One of my students (and friend) has a house in Alaska on Lake Clark. He owns a Super Cub and has been trying to get me out there for about six years. I really need to take him up on the invitation. Anyway, nice solution on the Stag.

Yes they are one inch squares. My various careers have given me various skills that are/were only good for certain things. Unfortunately nothing that I can make money with now that I am a geezer...
30 years ago I could really shoot tight groups...

I need this done for my stag. But I have neither the equipment nor the confidence. I guess I will have to pay ADCO to do it, or someone else. Even though they only charge $15, I'm sure I'll be out $25 shipping both ways, so then I am up to $65.

Where are you located at Mike?

Dallas.

 

[ron169]

Lol, Im quite positive there has got to be a local member or local gunsmith that can help ya out with the feed ramps

 

[Awake777]

I don't know, it's a small town in the middle of nowhere.

Mike, I put a post on ARFCOM for a Dallas area AR gunsmith for you. Let's see if we get any responses. Several million people in the DFW area, I'm hoping we can find a 'smith for you.

FloatPilot... congrats on the group improvements, and great job on the 6.8 Alaska Feed Ramps.

Definitly need to email those pics to stag... that is certifiable proof that the M4 feed ramps make a huge difference to the accuracy and reliability of their rigs....

Super idea... this could also be posted in Stag's Industry forum on AR15.com, and in the Variants section. :twisted:

Looks like a nice improvement including your picture post. :wink: Refresh my memory, what tools did you use? Chain saw/rat-tail file, dremel? I can see stiff competition in the first quarter shoot.

thanks, I hope someone pops up who is good.

 

[cwlenz]

Thanks for posting the info and pictures. I'll definitely look up when my rifle comes in.

 

[Bushdog45]

Great job Float! That is exactly what my Stag needs. It shoots fine with most loads except 90 Sierras but I want it to be reliable with all loads. I will send mine to Adco soon. CMT makes parts with the M4 ramps I believe and why they don't use them is beyond me. :? I just replaced the stock spring with an SSS flatwire but have yet to shoot it. Thanks for the report.

What Dremel "bit" did you use to make the ramps? They look nice. 8)
