Marauder Hammer Adjustment Hole Plug - Size?

May 20 2010 at 3:28 PM

Does anyone know what size the back hole is? I would like to input a plug but I am not sure what the size it... and I really don't want to go to Home Depot with my rifle in hand.



Blessings,
Jeff

I just do not wish to pay that amount for a simple bolt.
I may go to Home Depot and purchase a few just to see.

OK...so figure an hour of your time to go to Home depot, gas for your vehicle, finding hardware dept...looking through all the bolts there to find one (hopefully) that fits,stand in line for ????? to buy say half a dozen,for $2.00, get back home and try them all in your gun..even if you have one that fits, then spend another 45 minutes cleaning bolt head up with file, then sanding smooth and polishing it up nice and shiny......yessir THAT sounds like a good idea ! Just being realistic....

has to to be something better

May 20 2010, 11:21 PM 

I use my thumb and fingers to gently pull my bolt back, with my thumb right on the hole.
Instead of using my arm to pull the bolt back.
I would prefer a plug that is flat and low profile.
But there probably isn't enough demand for someone to make one.

Head down to auto parts

It will harder to take in and out but those nylon trim panel pins come in all diameters and ya can just clip shorter and push it in and it will sit flush . Harder to get out but still very doable.

I use a set screw, it sits flush

a smear of purple locktite keeps it from moving until I want it out.

The plug needs a small vent hole (as crosman designed the hammer/spring arrangement).

May 21 2010, 8:23 AM 

Plugging the hole completely will change the hammer performance. As the hammer moves forward, if a vent is not available then a slight vacuum will occur and slow down the hammer. I agree it would be nice to have a plug for that hole.

question??

May 21 2010, 9:35 AM 

so that big ole slot for the sear doesn't reach far enough back to vent the the area via the trigger group???

I will have to take a look if not I will have to drill a 1/16 hole in the plug

I will run a shot string with plug vs without and see

I grind flats on the side of the striker. works better than a vent

May 21 2010, 10:38 AM 

since friction goes gown as well as weight, vacuum effect and piston effect.

Thanks ya saved me from wasting some 25 cal pellets

May 21 2010, 7:24 PM 

I sorta figured that sear slot under the hammer would extend far enough to vent any suction that might try and be created

Actually, I think the hammer travel is vented through the breech.

May 23 2010, 4:56 PM 

When disassembling the rifle, I noticed that the hammer/striker assembly travels inside the tube which has a slot for cocking the hammer. The breech bolt removal opening vents that location. So, it appears the hammer is vented whether the adjustment hole is plugged or not.

My original comment was made based on hearsay and not from disassembling the rifle.

I could do a lower profile one also!

May 21 2010, 7:11 PM 

but then it would be just like a bolt!

Those things are soft, thin aluminum. The one appropriate for plugging the Mrod hole would have a thin, easily damaged rim exposed when installed. If one pushed on it with a thumb while cocking the bolt, the rim could flatten.

I have a bunch of them in old toolboxes. New hydraulic and engine parts came with them, and most other mechanics just threw them in the trash. I should have, also.

The real plugs are pretty cheap. Here's a place that sells them for less than a buck:

You would need a -03.
