Marlin Papoose Over-Barrel Suppressors
The 'Papoose' is an excellent little take-down rifle
I've had heaps of fun tuning and modding them over the years
Photos and video below are of just some of them...
Enjoy
Thought you might like to see the project and process of suppressing these excellent little 'survival' rifles.
You've possibly heard negative comments about the accuracy of the Papoose - due to the barrel being removed to take-down, and the scope remaining on the breech. Personally I've not had any great issues with accuracy due to this design. I find the fitting to be very tight and positive. The worse alignment I had one day, was around 100mm at 35meters.
What I often do - is leave the Papoose assembled. However, if I do need to take it apart, I take my laser bore-sighter with me, or better still - mount a lazer permanently on the barrel that retains accuracy even if rifle is dissembled.

1:- Having received the barrel, the first job is to cut a clean and crisp thread - 1/2" UNF x 20tpi.
Normally I can't thread rifle barrels, as my lathe is not able to accommodate the barrel. However, a Papoose is a take down unit.
2:- Now the fun begins, crafting the flow-through chamber that is positioned in the middle of the suppressor, allowing gases and noise to reverse-flow over the barrel.
This piece it the most challenging, as even a small error in alignment or position will result in uneven distribution of combustion gasses - resulting in a inaccurate bullet path.
3:- Centering the over-barrel suppressor in the lathe, and porting the muzzle-brake in the style of a shamrock (requested by my customer who is Irish) I think a shamrock is a three leafed clover.
As with the internal flow-through unit, it is vital to position the external muzzle-brake symmetrically around the barrel
4:- Some of the internals. The suppressor is tapered to the diameter of the barrel, and the suppression ports are reverse venturi flowing - basically shaped like a cone to trap and disperse maximum sound and heat.
Main body and suppression ports are crafted from pre-sized high grade aluminum. Suppression spacers are from high grade steel. End-cap and venturi units are made from solid rod.
Rear end-cap is crafted from heat resistant high grade polymer. The mirror finish is accomplished by a two stage buffing process.
5:- Suppressor is almost finished, and since requested to finish in a matte-black, I am undercoating the unit first to make it more durable when the silicon coating is applied.
6:- Now, some engineers wouldn't show you their mistakes - but as I say to my congregation each time I preach - 'I am only human, and make mistakes like everyone :-)'
So, photo 6 shows what happens when I get my chemical ratio wrong on the silicon coating!
7:- After an hour of correcting my last attempt - here is the suppressor - finished and ready for testing!
Suppressor below was made for a customer.
The Papoose is one of my favorite rifles. They are very accurate, very light and extremely well balanced.
This baby looks very clean - with tight lines and well balanced.
Suppressor below is my own. Very clean, very light and very quiet.
Actually, I've since sold this one - as a customer contacted me with a price I just couldn't refuse :-)
Below - another Papoose I kitted out
I wanted a military look for this one
My latest project is below.
Undoubtedly a customer will offer me a price I just can't resist, but at the moment - I am enjoying this excellent little rifle for myself!
I have fitted this Papoose with a 2-6x32 scope, with matching sunshield and muzzle-brake
I also crafted a full over-barrel suppressor - made with my lightweight bio-tech internals that allow full wet-fire
I really like this kit. The Vector Optics is an excellent compact scope!
