Sorry if this has been asked already somewhere but I am trying to find the dimensions of the spas 12 handguard for a NFA pulse Rifle build. Since the spas 12 parts are so rare my FFL may have a guy who can mill them but need actual measurements. This is the last thing I need prior to sending off for federal permits. Any info will help thanks in advance.

Best thing to do is find a spas on your local trading pages. I found one and traded a remington 870 and remington 700 for mine. I may be able to help with measurement. What specific measurements do you need?

Just let me know what measurements you need mate, I’ve also done a 3d printed replacement heat shield and pump grip for my Spas12 deac.

Just let me know what measurements you need mate, I’ve also done a 3d printed replacement heat shield and pump grip for my Spas12 deac.
Hey man thanks for the help. I need the overall length width and height for the heat shied. Knowing the inside Diameter would be great as well.



I'd dismantle a spas 12 if I could find one but they are 3-5k currently.

I take it you 3d printed with resin? They look amazing. How sturdy is it? I'd attempt it but don't think it would hold up to actual heat of the gun barrel after a few rounds.

When I get this thing done and all the federal paperwork completed I'll post some pics

Edit: would you be willing to share your cad files and stf files? Much thanks that's probably all my Smith needs. Much thanks again

Yeah I’ll dig the files out for you mate, the only thing is I’ve had to make the cage and pump grip a tad oversized so it can be fitted without breaking it, it’s not noticeable unless you put them side by side tho..
The Spas cage in my 3d printed PR kit is smaller...
