There a few minor problems with the Bostitch F21PL framing nailer. One is that it is noisier compared to most nailers we’ve checked out so far. Another is the depth adjustment design. The tips keep on moving and can also send nails way too deep if not given attention. Lastly is it isn’t ready to use out of the box. You’ll need to buy an air supply fitting separately. Thinking about these minor flaws, the pros outweigh the cons so it’s kind of good.

  • Noisy than the most nail gun
  • Has a bit of problem with the tip/depth adjustment design
  • Need to buy the air supply fitting separately

What people say who bought the Bostitch F21PL

Wondering what people who had bought this Bostitch F21PL nailer thinks about it? We’ve gathered some of the Amazon reviews of this powerful tool. Check it out below and also read how this framing nailer had changed their lives.

 K. Barlow

“So far it works great! I like that it comes with the positive placement attachment as well as the normal tip. I used it to put up a fence and had no issues. Just be forewarned: you need to order the NPT nozzle separately. No idea why this isn’t included as it seems to me you can’t use the gun w/o it. Not a big deal so long as your aware though.”

 T. Rice

“Purchased this nailer because while I value quality tools and quality engineering I couldn’t justify a Hitachi NR83A3 for my summer fence project. I ran about 1250 2″ ring shank stainless steel nails through it and the only time it misfired was when I forgot to add another stick of nails. Even then it never jammed.

So, while I’m not a contractor and treat my tools as if they were glass, this is a great nail gun and the only thing I miss are the envious looks from those who recognize that it isn’t a Hitachi.”

 Dr. Thom

“Used for total deck (support base) re-build, from post supports (nine), upwards. HEAVY DUTY and (somewhat) heavy in handling. But, once adapting to weight and “feel”, learned how to minimize my “muscling” of the tool and used more appropriate movement and body positioning to increase speed and accuracy. (Would have been very hard to handle if I had used a battery-powered model.) Now, the question is: What do I do with a tool that I love, but don’t need anymore?

My Baby!!!”

W. Waterson

“Can’t complain about this gun. Bought it for remodeling my house and we’ve used it for everything from framing to putting on the siding. Shoots 3.5″ nails through cement board siding then 2″+ of wall and stud. The only thing I don’t like is that the little rubber framing cap (that covers the spikey framing head) fell off and I doubt we’ll ever see it again.”


“Best production framing nailed out there. This is my second one. The first one is nearly 18 years old and has been used intensely for most of its life and is still going strong. Bought this one for the school district maintenance and operation department where I work as a senior carpenter. I didn’t even consider any other brand or model. These things are built like tanks. Few parts sturdy depth adjustments without the flimsy knobs and exposed springs other brands use. It can fall off a roof bounce off your ladder and land on concrete and you just pick it up and go back to work. I know because mine has several times and I’ve never needed to stop working or even think about having to repair it.”

The Verdict

You can order this product and use it for both small-repair works and full-time construction jobs. Because of its thoughtful design, lightweight, and durability, we would highly recommend the Bostitch F21PL Framing Nailer to you.
