scout mount from sportsmans accurize the mini?

[guncats]

$90, not bad, but the stainless bracket shown in the picture puzzled me: is it for securing the back end of barrel from underneath the scout mount? If so then it will really stiffens the barrel and reduce the spread(as descriped on the web page).....

Has anyone tried this mount before?

Hey Guncats, got that mount on my gun, you can see it on the topic mini scout carry handle. I believe if you punch in amega ranges youll find one for 80 if opt not to buy the tactical light mount. The mount is perfectly contoured to your barrel. Its hard to explain how it attaches without being confusing, but I can tell you that it is very rigid. If you want I can try to scan the instructions and post them.

[tinman]

Oh heck, Ill try to explain anyway. One side of the clamp is inserted into a groove, the barrel is then placed in the recessed mount. The clamp then pivots over the barrel and is tightened down with two screws. The clamp is one inch wide and lands 3 1/2 to 4 1/2 inches from the reciever. The back end of the mount saddles nicely on the barrel just in front of the reciever. There is a minimum of three points of contact.

:huh: :blink: Since it is attached with a half round strap around the barrel from underneath,what keeps it from rotating on the barrel a few degrees from a sharp tap or rap against it or a scope mounted on it?Looks like it could be knocked off center if not careful!What do you do for your upper hand guard? :confused: :sniper:

One last thing, Im getting wordy now. After installing the first time my groups got worse. The second time I paid a little more attention to the instructions and to gapping the gas blocks. After that accuracy was slightly better with it than without it.

I think just a careful reassembly job on the gas block is a great idea.

magnomark, I believe it IS the handguard ... and the upper half of the gas block, too. That's what keeps it from moving.

[guncats]

Thanks for the info, Tinman!

The clamp explained the rear mounting area, does the base also have a front mounting point? (such as attaching to the upper gas block?)

[tinman]

Give me a day, Ill take it apart and try to post some close-ups. A picture is worth a thousand words. The mount is very stable for its intended purpose. It has been transported in a hard case with both a eer scope and a red dot and has held zero. But it does not compare to a good set of Ruger rings.

:lol: AHHHHH...........I see it now!!!!!!!!! <_< :sniper:

[tinman]

1-hook clamp into recess of body mount
2-place barrel in mount body
3-rotate clamp over barrel and thread screws. Do not tighten screws to allow movement for gas block installation
4-Install gas block,gap evenly and tighten correctly
5-Tighten screws on barrel clamp

About 40% of the barrel makes contact with the rail. It seats nicely in the contour and is rigid

[tinman]

The only scout rail I have owned so I have nothing to compare it to. Would I buy it again? Yep,especially at that price, I would also install a shock buffer and cut 1/16 of an inch off the barrel clamp to keep the op rod from tagging it.

[tinman]

The height of the rail in refrence to reciever mounts. The rail does not obstruct the use of a 32mm scope on original Ruger rings, but the lense cap needed to be notched out. This makes it versitile for plinking, target shooting,hunting or social work.

[tinman]

Just something that may help avoid confusion guncats, The manufacturers picture shows only one side of the clamp, the side with the two holes for screw mounting. The other side of the clamp not shown is angled out 90 + degrees. The mount body has a cavity for the angled part to set in. The angled part of clamp has to be inserted in the cavity before barrel placement. Hopes this helps,I can see how it would be a pretty wimpy mount if it wasnt attached on both sides.

[guncats]

Thanks! now I know how it works...

now since the upper area of the barrel contacts the mount and cools faster than the lower half barrel, will the cause the barrel to bend after heat up and cause the point of impact to rise more?

I was thinking about a barrel reinforcement utilizing the rear barrel and gas block to attach to the barrel, now this mount does excatly that, even with optic rails on top.....

[tinman]

Guncats, I dont know if this answers your question or not. In my opinion for what its worth, I have no expectations of the rail, strut or any attachment to change poi under the stresses of a hot barrel. I like the strut because the next shot can be taken sooner. Sorta kinda like a vent rib on a shotgun barrel. But dont give up on your ideas, the greatest inventions were the ones that someone said couldnt be done. Keep the gears in your head moving, you might be on to something.

I actually did some experimenting with barrel stabilization before the gas block (as opposed to after the gas block which my rigidity strut addresses). I removed the handguard and stabilized the barrel about midway between the chamber neckdown and the gasblock using a simple metal hose-clamp, the kind you use on radiator hoses. While I found that the POI was affected, moving it up a couple inches as I recall, it seemed to do nothing to affect group size per se.

So my guess is the barrel mounted rail system you're installing will have minimal effect on accuracy. But by all means try it, that system may behave somewhat differently than the hose clamp idea.

[guncats]

The reason I asked was that my understanding of cause of mini's poor accuracy is mainly the op-rod will press against the gas block to make it bend upward before a round is fired. This push force can be quite consistan since it is determind by the spring press. But the point where this force will push varies from shot to shot, ie the op-rod never contact the gas block at the exact same spot every time, this cause the barrel's upward bending amount to vary from shot to shot. The scope is mounted on the receiver so when the barrel bent differently the scope aiming point doesn't change accordingly, ie the scope is pointing to the same spot while the barrel is pointing slightly differnt every time. (Have I confused anyone so far?)

If the barrel before the gas block is more stiff, the barrel's upward bending amount will be reduced, therefore the variation of bending from shot to shot will also be reduced (amount, not percentage), therefore better accuracy.... Installing a scout mount with two attach point should stiffen the barrel a little (area before gas block), so my theory is it should improve accuracy?

Kkina, thanks a lot for your post, I was about to do a similar test, now I know it probably won't change accuracy much. You just saved me at least a weekend... :P Theory is just theory I guess, if the practice result show otherwise, then... :rolleyes:
