The sticks will handle the weight but the friction rotation in the z direction on the 2 point gun rest will not support a heavy barrel gun plus a heavy night vision setup. It is best suited to a light gun and light scope setup.That's great info thanks very much.
I am considering them for NV foxing where I would hopefully be able to leave the rifle mounted in position (lashed onto the rest?), so I could be free to scan about. The rifle is a modded heavy barrelled varnint with another 3lb of NV on top, so maybe the Primos won't be up to the strain?
I was also hoping they might stand a bit of rough abuse being clattered about in practical comps such as the RBL Precision with a heavy 308 but they might be too fragile.
Just out of interest, what is the procedure to strip the sticks down?. I thought they were sealed units.. My question is if easy to strip might be worth taking them to bits and cleaning them before they fail.As previously posted on here I was a great fan of the tripod trigger stick, so went and purchased the gun rest. Unfortunately I found the link between rest and tripod was too flimsy to hold a loaded rifle with all the bells and whistles in a rigid manner. No matter, as the tripod seemed to be a good bit of kit until ... the clutch mechanism started to play up on two of the legs. They stopped deploying as they should and if assisted by hand made a God-awful grinding noise. I stripped them down and found that crud in the clutch cams was causing the problem. Cleaned everything up and things were fine for a bit and then the problem recurred, with ever stronger pulls on the trigger completely failing to release the clutches. Another strip and clean revealed that hard pulling had worn the heads of the operating rods into the plastic housing so there was insufficient length of pull to release the clutch.
They are really good bits of mechanical engineering that do a great job of providing a traversable rifle/camera support that readily adapts to varied shooting heights and uneven terrain. Sadly the fabrication and materials aren't up to the job. My sticks didn't get abused or hammered over harsh terrain - my stalking is a leisurely stroll about lowland hedges and woods. If they can make a set that keeps the crud out of the clutch mechanism and beef up some of the plastic to metal bearing surfaces I'd certainly buy them again. Until they bring out that sort of upgrade I'd give them a miss.
Yes they are and the manufacturer/importer states that there are no user serviceable parts involved... However, the 'procedure' is to get thoroughly ticked off with squeaky legs, then:Just out of interest, what is the procedure to strip the sticks down?. I thought they were sealed units.
Brilliant!! as a Mech Eng I reckon I can follow that procedure .. My pair have been very good and used a fair amount, but have tried to keep them clean as much as possible.. Just recently though there are signs that they are starting to stick, so a bit of maintenance looks to be called for.. I also use the Viper flex quad sticks supplied by Hammond sporting, very good sticks and well made, but a few design flaws ref noise, 1. the adjustment holes whistle in wind, sorted by taping them up as its the lightest option. 2. The top rests are too hard and dent wood stocks. Sorted by taping pipe insulation foam over them. 3. The legs are aluminium, which is good, but very "clickey" saw a clone set at the Game Fair that had soft foam on the leg at various lengths and that does seem to stop the legs being able to click against each other, so that is the next fix. A combination of the Primos tripod and the Viper flex quad sticks covers nearly all my shooting needs. Of note I also purchased the Primos bipod trigger sticks and now do not use them.. way too much variable flex for me, even with the top clamp bolts tightened.Yes they are and the manufacturer/importer states that there are no user serviceable parts involved... However, the 'procedure' is to get thoroughly ticked off with squeaky legs, then:
a. Apply high pressure washer in an effort to hose the crud out of the sticks.
b. Whirl said sticks about head in an effort to remove moisture.
c. Watch single lower leg detach itself from tripod assembly and disappear over garden hedge...
e. Retrieve leg and examine exposed clutch assembly.
f. Have light bulb moment thinking "Oh, so that's how it works...."
g. Proceed to shed with bits of trigger stick, open tool box and disassemble, starting with the bottom retaining plate under the trigger.
The lower legs are a twist/push fit with some sort of adhesive which clearly has little resistance to centrifugal force. Once they're off and the plate below the tripod head is removed it's obvious how the whole thing is put together. I'm a mechanical muppet and even I could work it out...
