I had an old mossberg 500A that had the light green stocks and a matte finish that would be almost what you wanted to do. You could find take off stuff out there.
Do some range time and see if you like the gun before you put too much work into it.
Mine was a good single shot shotgun, but I could never get it to extract shells reliably so down the road it went.
Sounds like the right side pump action bar angle notch and shell retainer bar notch angle were off.
Common problem in the mossberg pump shotguns.
Easy fix actually.
Nothing wrong with the gun and components on it.
Know it well.
Just needs a appearance freshen up.
Slumlord bought it used long ago for 2 benjamins.
Thats what I gave him for it.
Made him take it .
He was wanting to give it too me for free.
We are best friends
But guns are guns in my eye.
He knows how I think.
The previous owner before him had some type of fugging elvis ring on his right hand and did that marking up of the receiver on the right side.
Only thing I can figure from it...
Fugging moron...........
I didnt want schuck out big bens for a new one.
Slumlord is done turkey hunting due to being a transplant patient and complications associated with that from immuno suppressant
Meds he is on and tick issue,s from all that combo.
Last time he turkey hunted was 2017 IIRC.
I polished out and burnished the barrel and forcing cone for him in it probably 6 or 7 yrs ago.
Told him to put a strut stopper extreme .670 in it.
He ran a low powered scope with turkey reticle on it.
Ran 3.5 LB,s #6
Was getting 260 in 10" at 40yds with it.
Put my stuff on it like all others
# 7 3.5 hevi 13,s
270,s low 280,s with a rhino. 670
I'm gonna run some of the combo 7 and 9 or 8 and 9 TSS thru it this spring.
See what it throws.
I like high pellet counts.
Have run 835,s for a long time.
Use em as trade bait alot .
Keep the choke, pad and sights to set up a new or used one.
Keep this one for good.
Been also looking at used black syn sets on web sites.
Like you said about used take off stuff.
Gonna be a after deer season project
Got plenty of time to mull it over.
Killed 3 toms with it this spring.
The stock is just too lite colored to my liking.
