Underneath the action just ahead of the trigger guard is the loading gate. The shells are pushed into the tube until the tube is loaded. Once 2 (two) shells are in the tube, press the slide release located just ahead of the trigger guard and to the rear of the loading area rearward and rack the slide rearward. This action will load one (1) shell into the barrel, allowing room for a 3rd and final shell to be loaded into the tube. To unload the shotgun, press the slide release rearward once again, and repeatedly rack the slide to the rear, ejecting the shells. Do this until the gun is unloaded.
I can't seem To find the lever to or Button to jack a shell from the shotgun
$200
Marlin started producing the 778 in 1979, production ended in 1984
I am not 100 % sure, but the research I have done indicates that they were produced from 1978-1984, with 1984 being the last year of production. The Marlin Model 120 is the continuation of the Glenfield 778 with some parts being interchangable.
you can find them here... http://www.e-gunparts.com/productschem.asp?chrMasterModel=082Zz778
In good working condition $150 to $200
It has value as a shooter only - not a collector piece. $100-$200.
I own a glenfield 778 without the magazine plug it can hold a maximum of 6 rounds on in the chamber and 5 in the magazine
That model has been obsolete since 1982. You might find a scanned copy available on one of the gun auction sites or eBay.
Could your model be 775 or 774, NO 778 model by Savage or Stevens
yes and they sell rifled slugs that shoot better
its a gun.Your Marlin model 778 shotgun is a slide action shotgun chambered in 12ga.Magnum.It was available in barrel length,s from 20in.to 38inches.It weights 7 3/4lbs. and was discontinued in the year 1984.Yours was made by Marlin sometime between 1969-1984.
This is actually a Marlin 120 with a cheaper grade stock. In good condition I would take less than $200.00 for a sturdy and reliable weapon. It has been mechanically compared to the Winchester Model 12.
