    Hey Guys,

    Want to give a shout out to Ryan over at Big Dog Steel regarding his Accuracy Interntional Spigot Rail Adapter.

    I have been using this adapter for several months now, even back to the older prototype, and I have to say the unit works outstanding.

    Being a fan of both the Accuracy International Platform as well as the Atlas Bipod this is perfect bond when using them both.

    However you are not limited to using just the Atlas Bipod, so you Harris users are not left out. Ryan @ Big Dog included a way to change the adapter to fit a Harris and even provides the sling stud to use.

    Here is image from the Group Buy Thread

    A key feature to using this over the stock attachment point, is, it puts the bipod forward of the stock which helps with accurate. The further forward towards the end of the barrel you get, the better off you are. So this definitely fits the bill.

    That little bit will go a long way to helping with accuracy. Trust me on this.

    For you guys who don't like the swivel, the excessive movement when using a spigot bipod on an Accuracy International, you can see where Ryan has added this tensioning knob to dial out the movement and to secure the adapter in place.

    This also makes it easier to take on and off, in the past I have some that are very difficult to get off, because the stud is a bit too short. Well this solves that issues with some older designs.

    So if you are looking for an option to mount a bipod on your AI Chassis, or AW / AE rifle, look no further than Big Dog.

    I have one on mine,and it's the only way to go!It's amazing how much more stable it makes everything having the bipod out more forward makes.

    Lowlight - I'm glad you like the rail system. A lot of time, energy and money went into them. Thanks for taking the time to review the rail.

    We do have these in stock and ready to ship. We also have plenty of Harris Adapters and AI Thumbscrews in stock as well.

    I love mine as well Ryan, they are a really well made and very well thought out unit. I love how it extends the bipod out a little further then normal. Help balance the rifle a ton. Makes a super stable platform which I am a fan of.

    I would recommend them to anyone looking for a quality product to help with the stability of your weapon system.
     
    Thought I'd reserrect this thread. I noticed the new Gen II mount is longer than the one pictured above. Reasoning? Was it due to the clearance issues with the Harris systems? I'm probly going to pick one of these up for my AT either way but I was just curious. I kind of like the older version being slightly more compact.
