Hi Beretta shotgun owners, I joined your ranks. Yep, I bought my first Beretta shotgun today.

A (slightly) used Camo A300. Are there any good videos out there on how to disassemble it, and what to lube?

Also I keep hearing about "shims", and how I can change the drop of the stock. If I'm reading it right, it doesn't come with extra shims, you just change the position one already installed. Do I have that right?

I took it out today and it cycled light target loads flawlessly.

Any other tips?

The A300 Outlander uses the same shims as the 390/391/3901. You can't adjust by moving them, you have to get a different matched pair. The more expensive models come with extra shims, but the Outlander is an economy model.

See the post near the top of this forum, on Disassembly of 391. The A300 is similar in many ways to the 391, and I think that post will help you.

A good video that shows basic maintenance and plug removal can be found here:

The A300 Outlander comes with a spacer and a washer, already installed, that allow you to adjust the drop and cast. It comes from the factory set up with D-65-DX, which is right handed cast (DX) and 65mm of drop. By taking them out and flipping them around, you can get left hand cast (SX), 50mm of drop, or both. It's about a 5 minute job to do it and you only need a philips head screwdriver, 13mm socket, and a bit of oil on the screwdriver to get it through the recoil pad easily.

If you want a finer drop adjustment, you can also get a new washer and spacer which gives you 55mm and 60mm of drop. These are available at Brownells for about $5 or $6 each.

This video will show you how to adjust the drop and cast. The video is meant for different models which are a litte more complicated than the A300 Outlander, but once you get to the spacer and washer, the procedure is the same. For the A300 Outlander, you just need to unscrew the two screws that hold the recoil pad on, then remove the 13mm nut and lock washer to get the stock off.

Thanks, what about cleaning the piston / "springy thing" on the barrel.

Thanks, what about cleaning the piston / "springy thing" on the barrel.

Clean the piston, the inside of the cylinder, the mag tube and inside of the action-rod sleeve -- basically anything with carbon on it -- with solvent or CLP. A little 000 steel wool goes a long way here. I leave them all lightly oiled but I think some people leave these parts dry, saving the oil for the bolt and action rails inside the receiver. Put the piston BACK IN THE CYLINDER when you're done; don't leave it around the rod.

The visible spring on the forward end of the gas cylinder is a gas valve for releasing the excess pressure. You can wipe it clean if it's fouled but this probably won't affect the function much.

There's a YouTube video by a Beretta gunsmith cleaning (I think) an A400. It's close enough to learn a lot. And read everything by the great Seamus. :wink:
