Editorial Review
This round head framing nailer is one of seven new heavy-duty air-powered nailers from the venerable Milwaukee, and the whole series is another testament to the red label’s unflagging quality.
At the top of our list is how incredibly light Milwaukee’s nailers are, even fully loaded, and their compact size makes them a cinch to tote and use, especially in awkward positions and at the tail end of a long day on the job. But it’s crowded at the top of the list: Despite their light weight, these nailers are heavyweights in the power department. The 7100-20 effortlessly drives 3-1/2" nails and, best of all, its reload indicator even alerts you when your magazine’s nearly empty. Loading more fasteners takes a couple of seconds at most, and that means more money in your pocket. Another big tip of the hat to Milwaukee for incorporating both sequential and bump firing modes, accessible just by turning a knob, so when speed is a need, you’re ready to go, but precision is at your fingertips too. We like the quality built into this tool, from the magnesium housing to the easily adjustable air deflector and muffler, as well as the convenient rafter hook for storage. The non-marring nosepiece won’t deface your work surface, and there’s even a self-cleaning air filter in the tool handle, keeping dust and dirt out of the tool’s workings – and that means longer tool life. In hand, this nailer feels great: light, comfortable, agile, and beautifully balanced. Tool-free depth adjustment is on-the-mark reliable, fast and easy. Contractors and roofers can’t go wrong with this one.--Kris Jensen-Van Heste

A Piece of Junk 
2008-05-11
I am a building contractor and seem to buy a new nail gun about every other year, having used mostly Senco nailers in the past. Most of my electric tools, such as drills, sawzalls, etc. are Milwaukee so I decided to give the Milwaukee nail gun a try. It arrived about a month ago. I was surprised by how much of it was plastic, but put it to work. For the most part it worked fine. This weekan employee was using it and somehow a driven nail ended up twisting around and catching under the driving pin. With other nailers, I had been able to drive the pin back to free the nail. I was not able to remove this nail, even after disasembling the nailer. All I can do is invest in a new nailer and it won't be a Milwaukee. If I could have given zero stars, that would have been my rating.
Wow!, I just wish I had lots more framing to do..... 2008-04-26
Paid for itself in an afternoon -- tons of nails, no jams, lightweight easy to use, no fatigue. This is what a framing nailer is supposed to be.
Very Happy 2008-04-16
I have smaller, finish and brad nailers, and this is my first framing nailer. I did the shopping dance and was wooed by the Milwaukee name and the reviews here and elsewhere. I used the nailer to build a wall and also sister some 2x8 PT lumber to basement ceiling beams above the level of my head, and was very happy with the results. It took a little time to get the depth adjustment right, but once there it was performing as hoped for. Construction of the gun is as good as one would want, and it is a simple matter to load more nails. Btw, I used the less expensive BC Eagle nails without any problems, and best of all, no jams. I would have liked a case for the gun, however. Milwaukee seems to push you in the direction of having to buy a case, whether for a circular saw, drill or this. I keep it in the shipping box it came in, which works for now.
As noted by others, the nailer has a 3/8" inlet. Since my compressor hose fitting is 1/4", I was forewarned to buy the adapters to fit my hose to the gun. My compressor is small at 1 gallon, and 3 or 4 shots of the nailer cause it to recycle. As a DIYer, this is not the worst issue I face, but there is enough oomph to drive the nails, which is the bottom line.

I'm not a professional carpenter so I don't have much to compare this to. I have used a nailer only a few times in the past. I must say that I am VERY happy with this product. It's very light and very easy to use. It seems to have plenty of power for standard wood and pressure treated. It kicks back very little and is pretty quiet. It seems pretty well made (although Made in Taiwan, not USA like most Milwaukee) but I'm not sure how well it would hold up for a production framing crew. I know it works great for homeowner-type use and you can't beat the price!
Another great tool from Milwaukee 2008-06-29
I have been using this framing gun for only a few months now, but I couldn't have asked for a better framing nailer so far. It being light weight is a big plus. I had a Porter Cable 350MAG but I much prefer the Milwaukee 7100-20.
A great nailer 2008-06-23
As a first time user of a framing nailer, the Milwaukee 7100-20 didn't disappoint. Once I found out that it will accept a range of nails (20-22°), it was smooth sailing. Reliable, easy to use, and jam-free. Even though it didn't come with a case, I would recommend this nailer enthusiastically.
Great Choice 2008-06-11
I bought this gun after reading several reviews and I'm glad I got it! Good price, light weight, well balanced and not a single jam yet. I used it to build a scaffold on the end of my house with Hitachi 3 1/4" nails, then 2 1/2" nails to apply the hardy board siding. Quick, easy, and accurate adjustment for nail depth. I couldn't be happier, and can't wait till my next project.
Milwaukee 7100-20 Round Head 2-Inch to 3-1/2-Inch Framing Nailer 2008-06-10
GREAT GUN! GREAT PRICE! Very light, easy to load, plenty of power and hasn't jammed in the first 2000 nails.
A Great Nailer, A Great Price 2008-05-24
I wanted to buy the highest quality framing nailer for my DIY deck project and was more than willing to buy a more expensive nailer.
After reading every review I could find, including these at Amazon.com, and after holding all potential units in my hands I chose to buy the Milwaukee unit.
Compared to the Hitachi this unit has the same nailing capacity and is lighter, has more features, and is about half the price.
I am going to be nailing my deck boards rather than screwing them down and I want to be sure that the nailer doesn't leave any marks. The Milwaukee nailer has a nice smooth head that touches the work when nailing. The Hitachi unit I considered had teeth like points where it touches the work.
At the time of this writing, the price of this unit is excellent here at Amazon.com.
Update: I completed my deck project using this nailer. I drove approximately 1,200 3 inch Grip-Rite nails with it. The nailer worked perfectly and never jammed.
A number of people have complained of not having a case for the nailer. I went to the plastic bin aisle in Wal-Mart and found a perfectly sized clear plastic bin with green handles on the lid for about $9.
