Google Accu-strut it will give you all the info. I think the strut was less than 100$ and very easy to install. Just give the mod. Mini and they will tell you what one you require.You can install it in about 15 min. just follow the instructions and you will have no problems. Where they tell you to use the blue loctite that they supply do it. I love mine and I still want to put a bipod on mine. Good luck and good shooting.
