Home Forums Hunting & Shooting Hunting Rifles Ruger Gunsite synthetic stock - not compatible with Hawkeye

I just got an email from Ruger customer service saying the Gunsite synthetic stock they sell is not compatible with a short action Hawkeye/M77 MKII.

Does anybody know why? I'm not concerned with a perfect match for the barrel contour. I am more interested in receiver differences. I thought a similar rifle in a different cartridge would be neat.

I bought a MDT chassis for the ruger scout. All I had to do to make it work for my 77, was grind a center feed ramp. The standard action has a stagger feed mag box.

Thanks for the reply. So you are saying the feed ramp in a scout receiver is different than a M77? Or did you grind a feed ramp on the chassis?

Also, the MDT website indicates a version for the M77. I did not see an option for the Ruger scout. I don't get why you had to modify it to get it work with the standard M77.

Sorry for the confusion, but this is helpful.

Detachable box magazine the difference?

detach mag is centerfeed. I had to grind the ramp on the action because it was a '2-humper'. like this....



just have to knock down the ridge between them.





other rugers of mine are '1-humpers'. I'll bet these would feed fine....

guys, I almost forgot. Mags for the 77 or hawkeye (non GSR) must be modified to work in the LSS chassis. I'd figger the same, if one was to try the GSR stock on a standard 77 or hawkeye......

Thanks huntsman! I never saw a dual ramp M77 before.
You have been a great help.

The only differences I know of are the Scout is centerfeed and requires a fatter barrel channel than a standard Hawkeye.

If you have a "1-humper" feed ramp and can live with a large gap along the barrel I think the GSR stock would work fine.

"Think" being the operative word. I have not tried either of my GSR stocks (laminate and synthetic) on a short-action Hawkeye.

I think maybe another difference is the way the ejector was changed to accomodate AICS style mags. I reckon if you was to put a std 77 in the stock, you'd have to mod the rear of the mag to make them work. CH, if you get a chance, try it....

The Ruger AICS mags already have material absent where the ejector needs to lay down after being depressed as the bolt moves forward. This is true for the 3- and 5-round synthetics as well as the factory 10-round mag. As near as I can tell, all AICS .308 mags share this feature.

I compared the bolt face, extractor and ejector to that in my Hawkeye .280 Remington and could not see any difference in the ejector, the ejector slot in the bolt, or, with the 3-round mag installed, the area where the ejector lays when the bolt is closed.

Just got back from the range where my long time hunting buddy and a son-in-law and I spent about 4 hours shooting the Scout and several other rifles. The long range berms were closed for dirt work so we stuck with paper at 100 and clay pigeons on the berm behind the target stands. The lightweight .308 Scout, with its iron sights, was the fun gun star of the day. With spotters I was able to tweak the ghost ring a tad to the left, after which virtually every shot broke a clay. I was aiming just under the clays so I suspect it will be perfect for 200 yards.

So it sounds like it may work (or require some minor mods) to get a short action Hawkeye to work with the GSR synthetic stock. A 19" 7mm-08 with 3 and 5round mags and open sights would be nice.

Another more expensive option is to get a McMillan Ruger GSR stock, CDI GSR bottom metal (which works with Ruger 3 round mags).

CDI makes a detachable mags system for the Hawkeye (not GSR) but I do not think it works with Ruger mags, which I think are not the same as AICS mags. They say some milling is required.

Kevin Wyatt makes a drop-in DBM for the 77. 5 rd proprietary mags, tho.....

If anyone is still interested, I weighed my synthetic GSR stock and its 1lb 10.4 oz

The idea of turning my Frontier .358 into a GSR tickles me...
