Did you ever want to attach a bipod to your Troy Alpha rail? So did I!
I've been waiting about a year(not intently) to see if the Noveske Troy bipod stud would ever come back in stock at Midway, PA, Noveske, etc..... It never has. I would gladly have paid Midway $9.85 for this part.
So I set out to build my own. I will tell you how to make one for yourself if you have the same aspirations I do: to sometimes mount a bipod on your Troy Alpha Rail equipped......well whatever you have stuck an Alpha Rail on. This could also be used to mount a sling I suppose...although there are better options for that, IMO.
Take one of these:
And cut it down to 0.825". The shank should be approx 0.450" from the end to the shoulder. Yes, there are shorter ones you can buy, but I do not know how long they are from the start. There is a very small window of usable length, so it's likely you'd have to cut a shorter one anyway. Get the long one. NOTE: put the nut (Yes! you need the matching nut) on the threaded section before you cut. That way you can remove the nut and it will fix the buggered up threads at the tip. I used a hacksaw and then touched up with a bench grinder.
Here is mine:
Now get some flat washers that will fit the shank of the stud. Make them as so:
The top is how they each started out.
The finished one on the left has been ground to have flat, mostly parallel sides, a width of 0.500":
The right one has been ground to have a diameter of 0.600"-0.605".
These measurements are very important. Bench grinder used here. Paint them afterward if you like.
Assemble as follows. You will need the smallest needle nose pliers in existance:
1.Put the round washer on the stud, insert the stud through the hole on the bottom of the handguard(or wherever you deem fit for a bipod).
2. Finagle with your tiny needle-nose, the flat sided washer between the barrel and the inside of the handguard and land it onto the stud, which is barely protruding through.
C. Mount the stud nut into your needle noses and put it on the stud. The easiest (only) way I found to do this is to hold the nut stationary and screw the stud into it.
4. Make sure the washers are seated properly and tighten the stud into the nut. This will take trial and error to get the stud indexed correctly to accept a bipod.
