Rock Sopmod Bipod Help

[LWILLIAMS]

I have this Rock Sopmod bipod and the aluminum on the base is being eaten away fast. I maybe have 200 rounds through this gun with this bipod and it is destroying the bipod. The gun is a 308 so recoil is of no issue. Is this normal for these bipods to do this and is there anything I can to to limit the harm I am getting.

They do rub so if looks is a issue not the best bi-pod but the other thing is mine are all steel so it has not rubbed into the metel but only the finish.

If it was just finish rub it would be no deal but this is physically eating into the aluminum. 1/8" or better and getting worse all the time.

Looks like a wrong "guess" on material selection by the designer....that is amazing.
Get your money back if you bought it from the company,it will only get worse as Hardcoat is generally only .001-.003 thick per surface and by the photo, that has been well exceded.

If they even hardcoated it to start with....

I took a very close look at the Sopmod when Mike first told me about it.
I don't think the bipods that I had were Type3 hard coat at all.
The wear spots were very apparent and immediate.
I'm no Metallurgist but....they should have been made in at least 6061 T-6 with a solid 3 Microns of Type3 hard coat.

Send it back and get a new one or your money back and move on.

Does anyone have any first hand knowledge of dealing with rock on these bipods. I was all amped up to get them and use them until this started to happen.

Aluminium is just plain "the wrong" material for that application.....

If the ops pic is telling the story and the material is indeed Al Aly ( shown gouged) being contacted by steel or S.S. under impact type forces with small surface area contact.

Re: Rock Sopmod Bipod Help

Yes I believe the leg portion of the bipod is steel but the clamp side that it rides on is aluminum.

Re: Rock Sopmod Bipod Help

the one i have on my AR-10 is doing the same,..but i have over 1000 rds thru mine.

i think eventually i'll have the AL parts replaced with steel.
