Sorry for the double post. I had originally posted this in the field target section, but after reflection felt this was the more appropriate section. I wish we could delete our own threads we start.
Hi everyone,
Have you been frustrated by the Primos trigger bipods and all the slop in them when the legs arent spread fully wide? Especially when the tripod version is rock solid when the legs are close together?
Have you had to try wraping hose clamps, zip ties, clamps, spacers etc to prevent the legs and yoke from moving too much?
Well I came up with a solution. I removed a leg from the tripod version and essentially made it a bipod but with the benefit of the collar locking the legs in the narrow position The yoke doesn't flop from side to side like on the bipod version. It still rotates and the legs extend and retract with the trigger as normal.
You can remove the trigger handle or leave it in place. I chose to remove it so that it wasnt in the way when rotating the tripod around. Also you might be able to remove the bolt holding the leg and the leg without removing the locking collar. However, I chose to remove the locking collar for ease of access and clarity in the pictures.
Tools you will need:
#1 phillips screwdriver
2, 3,5MM allen wrenches.
Needlenose pliers or tweezers
1. Remove the 2mm allen bolt holding the handle backstrap shown in figure 1 then remove handle backstrap.
2. Loosen 3mm allen bolt shown in figure 2. Remove handle assembly
3. Spread legs to the full wide position then remove 3 phillips screws holding spring retention cover. Remove cover. Figure 6
4. Move legs to narrow storage position. Carefully remove 3 springs from studs. CAUTION studs can come out easily so try to avoid this. Remove locking collar by sliding down legs. Figure 7
5. Remove 5mm allen bolt holding leg you desire to remove. Only one bolt needs removed. I made arrows showing what the bolds look like from different angles.Remove leg then reinstall bolt and tighten so its not lost later. I saw no difference between leg assemblies so it shouldn't matter which one you remove. Figure 8
6. Slide locking collar over remaining legs. Once into place reinstall springs onto studs. Figure 7.
7. Spread legs fully wide my rotating locking collar. Reinstall spring retaining cover with 3 phillips head screws.. Move legs to narrow position if desired. Ensure locking collar moves freely and operates with spring tension. Figure 6.
8. Reinstall handle assembly. Ensure plunger, Figure 4, goes inside barrel assembly, Figure 3. Ensure handle is fully seated.
9. Tighten 3mm allen bolt. CAUTION Ensure bolt engages groove shown in Figure 3.
10. Reinstall handle backstrap Figure 1 and check operation of legs and trigger.
Down the road, should your trigger get mushy or isn't operating the legs properly, check for vertical play with the handle assembly. Its likely the 3mm Allen bolt, Figure 2, has gotten loose allowing for the handle to move vertically. Push handle assembly into the body and tighten the 3mm bolt.
I also included pictures of the leg operating mechanism. The plunger, Figure 4, engages the roller on lever, Figure 9, which activates the ball valve (for lack of a better term) Figure 10. Depending on your use this may need to be cleaned at some point.
I hope this helps and that its understandable. I'm sorry I wasn't making notes as I disassembled it as I thought part way through to take pictures and to do this writeup once I was done and ensured it worked.
