Hey all been pondering the idea of welding a piece of a tactical rail to the bottom of the barrel of my Charles Daly 12 ga. Semi auto. Was wondering if this have been done before or if anyone has any feed back on this procedure. I know that too much heat can ruin the barrel but it wouldn't take much of a bead to tack on a small section of a rail. The reason I want to do this is because my CD has the vent running the entire length of the top of the barrel and I can't find any type of rings that will clamp onto the barrel. I think if just the rail was there it would be easier to remove and install items of my choice, ie; flashlights, lasers, or even a bayonet :grin: Who knows what I'll do for right now. Was just curious.

I know I've seen them somewhere, can't remember where. They make a 3 sided tactical rail that attaches to the barrel on a shotgun with clamps. I WOULD NOT weld it, you could create a weak spot, or warp the barrel causing it to explode. :shock:

That or you might see if they make a foregrip for your shotgun with the rails built in. I know they do for the 500 and 870.

Just a thought, how much are you looking to do to your shotgun? Really? If you want to do a rail and maybe the stock, possibly a side-saddle, blah, blah, blah, you might be better off picking up a 500 or 870. I have an 870 and love it. The 870 has the most aftermarket accessories available with the 500 not far behind. You can pick one up for cheap and build it how you want and it will probably be easier than trying to find all the pieces for your CD. Just a thought.

You guys can flame all you want, but that can probably be welded ...with a great big BUT. Your average welder could not pull it off. An extremely exceptional welder could with the right equipment and a proper procedure developed through trial and error. Barret welds their barrels with zero defects, although this type of barrel is a completely different animal. I would not do it in my shop....the liability alone would be a killer.

What it would take is a Pulsed TIG machine. No other machine would be able to run it correctly and control the heat enough. IMPO, a transformer machine would not be able to pull it off sufficiently. IMO, it would take an inverter unit that can cycle the pulses much faster than the transformer units could ever do. That pulse is how you control the heat....without it, you will damage the barrel. This fact pushes the welding out of the reach of most due to machine cost. That type of unit will start in the $4k range.( No, the cheap Chi-com units couldn't do it.) Even with that type of unit, only an ultra-experienced hand would be able to pull it off. Just having the machine doesn't mean you can run them correctly. I see this all the time. The machine is smarter than the weldor. Those units have a very steep learning curve.

Bottom line, get a clamp on model and save yourself the hassle.

They also sell 2-screw rails that can be screwed into the handguard of shotguns too. I'd probably put holes in my handguard before trying to weld onto the barrel.

Yea, but you could Silver Solder or braze it in about 5 minutes ... That's how the rib is held to the barrel ;)

Even so ... I'd just get a clamp on model as you suggested !!

I have looked at all the different style of clamps but none will work with the vent rib that runs down the entire length of the top of the barrel. All the clamps are made to work with smooth barrels.

The reason I did not go with a Mossberg is because its been done. I wanted something different and I found it with this shotgun.

If you know me personally you know I do not like to have the same as everybody else. I like to be different and that usually means I have to build my own parts. If I can't do it I have friends at different machine shops. I'll get something figured out if I have to build it myself.

Thanks everyone for your opinions and feedback about this.
