    in Rifles (Spring)

    Posted · Edited by Pendra

    I just received one for upgrade. My task is to meld this M99 with a heavily upgaded L96 (SP210 spring and the like). So I took both to bits and here are my findings:

    - The L96 mag does NOT fit. The L96 mag is longer by about 1cm and a little bit wider.

    - The L96 cylinder does NOT fit. The L96 comes with new type thick handle boss, while this one requires a thin APS2 version. Otherwise looks perfectly like a stock L96 cylinder. Down the the pressed cylinder/handle boss connection, which is the weakest spot on the L96. I don't recommend any spring that is stronger than the original.

    - The Type96 Zero Trigger does NOT fit. One screwhole is about 4mm off. Also the sear is a very tight fit, some dremeling of the receiver is in order.

    - The inner barrel, and hopup rubber is stock L96 type, but the barrel is about 95mm longer than the in L96. The factory spacer is better than the L96 foam spacers, but still leaves a LOT to be desired. The Hexagon Product spacers will mean a definite improvement.

    - The hopup unit is different. It has a sliding setting (similar to VSR) instead of the screw setting on the L96s. It is hit and miss because the sliding is a nice, but there is nothing that "locks" the slide in place. No screw to tighten, so spring to lock, no nothing. Therefore it can set itself off very easily. You can install and use a PDI L96 hopup unit, but you can NOT use a stock or a Hexagon Product L96 hopup unit without mods.

    - The bipod is heavy and oversized by about 1.2/1, interesting.

    - The takedown is laughable. Pins do nothing, you need to remove the rail and a dozen of tiny screws to get to the gun.

    - There is a small white plastic ring that connects the trigger with the sliding wedge that hits the trigger on the trigger house. That plastic ring is under some stress and I'm sure it will be the first thing to break.

    - The trigger house is metal, but it has the same problem as the plastic L96 trigger houses. The tabs that connect it to the receiver are thin. Hopefully pot metal lasts longer than plastic.

     

    My rating of the gun: Not impressed. I was considering to get one, to make my Barrett family complete, but not any more.

     

    Now the modifications:

    - The donor L96 is equiped with a OK L96 cylinder, which is old type by default and it has an extra ring to turn it to new type. With the ring removed, the cocing handle fit perfectly onto the handle boss. The screw at the end of the cylinder is bigger than the original M99 screw, so I will drill up the end bit to allow the L96 screw through.

    - The donor L96 came with Hexagon Product L96 hopup unit and AEG barrel. While the hopup unit fits into the outer barrel, you can't really use it because you can't set it. The outer barrel lacks the hole to access the setting screw. I will drill a hole into the outer barrel so the setting screw will be accesible. Oddly enough, while there is no hole on the outer barrel, there is a hole on the lower receiver. So I don't have to mod the receiver.

     

    As a sidenote.

    The M99 hopup unit shows some potentia. I will attempt to fix it up and fit it into my L96. However the lack of decent hopup rubber is still a problem.

    Even a stock TM gun can pierce a coke can on one side. One of my gun is around 1J and it can go through the bottom of a can, so you can't rely on that. Chrono would be the only way to check the FPS. If it is over the limit then just downgrade the spring to a 1J one and it would be fine.

    The PSG1 differs from all normal AEGs. It puts the spring under tension at the end of the cycle. So at the very moment you pull the trigger a BB comes out. On normal AEGs the piston is all the way forward after a cycle. So if you pull the trigger on semi, the piston has to move all the way back which takes some precious time between the trigger pull and the actual shoot. However you can easily ease the spring by firing the gun in semi.

    As it is not possible on PSG, you need to release the spring manually. As the M14 lacks the semi, that tool is the only way to release the spring. The other would be to know the when to stop pulling the trigger.

    If you don't ease the tension of the spring after use the gun will soon loose power.
