Franchi SPAS12

Specifications, Parts Diagram, and Sources

Specifications  (Click here for full factory specifications)
GAUGE/CHAMBER 12 ga.  2 3/4 inch chamber (Do NOT attempt to shoot 3" Shells. Why not?)
OPERATION  Pump action or gas operated semi-automatic
BARREL  21.5 inches
CHOKE Cylinder  (Note 1,2)
SIGHTS  Ghost ring sights
CAPACITY 2, 6, 7, or 8 plus 1 in barrel  (Note 3)
WEIGHT, EMPTY 9 pounds 10 oz.

Note 1: Everybody says "Cylinder", but every SPAS-12 I've gauged has been halfway between "3/4 Choke" and  "Improved Cylinder."  Then I did some measurements and found the whole barrel is between the diameters of a 3/4 choke and an improved cylinder, right from the forcing cone to the tip of the barrel.  So, it isn't choked but is undersize.  I found out this is not uncommon on European shotguns.

Note 2: Other external choke tubes are available.

Note 3:  A very complex question. Franchi's brochure says 2 + 1 or 6 + 1 with an extension.  The picture they show has an extension one shell short of the full barrel length.  Most guns I see have a longer extension that is the full length of the barrel, which would then make the gun a 7 + 1.  Many folks say the gun is 8 + 1 because it is possible to put 8 crimped-type shells into the 21.5" magazine.  And if you use end-disk type shells (which are longer), the maximum is 7 in the magazine. (See Magazine Capacities for more info on the effect of shell types.)  The FIE User's Manual says 8 + 1.  The original Franchi export manual says 7 + 1.
I prefer to use a spring meant for a 10 round magazine and only put 7 shells in to give it the extra room it needs -- I've seen the factory spring fail to feed that 8th shell on many occasions.

Exploded Parts Diagrams

and improved 300 DPI!!!

I found that the original drawing from Franchi for the SPAS-12 was incomplete, and that a few more parts and details relevant to the SPAS-12 were in the LAW-12 manual.  So while this remains a SPAS-12 diagram and list, it has been augmented with information from the later manuals.

Source - Chris (your host) Is Making Certain Parts

I have begun to make certain parts that have become unavailable or overpriced.  It was a shame to see guns taken out of use, sometimes parted out, due to the lack of a small plastic part.

Scott C's Parts

Scott used to be a good source of parts, but as of late he only has over-priced junk and is passing out some really bad information.  I'd stay away if I were you.

Tips - Parts Scarce As Hen's Teeth

The SPAS12 and SPAS15 are no longer in production and Franchi has changed hands since they stopped.  Parts are becoming hard to get.

These are the parts that seem to be in demand, but difficult to get.  I'll also add the availability and last price I saw for each:
Folding Stock (don't forget, three types)
$420 - $475
Hook for Stock (OEM)
Very Rare
$125 - $300
Magazine Extension (long)
$200 - $300
Magazine Extension (short)
Trigger Group (Cross-bolt)
Trigger Group (Lever)
Choke Tubes
$65 - $149
Divertor or Spreader (both pieces)
$400 - $500
Scope Mount
Something over $300
Factory Tool
$52 - $82

(Any emails asking where to buy any of the above will be ignored.)

You will never, ever be able to buy a replacement receiver, just a new gun.  The receiver is considered to be "the gun" by the ATF, so importing a receiver is importing a gun, which is banned.

Tips - Receiver Shock Absorber -- Part #6

There are two styles of Receiver Shock Absorber, Part #6.  They are generally called the "new" and "old" styles:

Old Style (Above)

New Style (Above)
Black part is metal -- can be ckecked with a magnet.  Many have a "belly button" in the middle.

Make sure you know which one you need and get the right one -- I sell them here.  Note the "old" style goes into a cone-shaped recess, the new goes into a cylinder-shaped hole.
