Review: Well worth the cost - I bought this for a one time job so I got the cheapest one I could find. I was more than happy with it. I framed an 18 by 20 room with it. No mis-fires, no issues at all. It is heavy (as expected) but very easy to use. Drove the nails into the structure as expected.
Review: Works great! - Great nail gun. Super happy with this purchase. I’ve had one before and got rid of it. Not knowing I’d be doing hang work again. For the price it’s worth it! Easy to use. Not to heavy. Nails to replace are decently cheap. I’m glad this was purchased for my husband.

## Questions & Answers

**Q: What kind of air compressor do you recommend for this nailer?**
A: It really depends on how you're using it.  If you're intermittently nailing with in and not imitating a machine gun- you can use a pancake or similar small compressor.  The working pressure of the nailer is 70-115 PSI.  I run mine at 100 PSI.  Any portable compressor should be able to hit that pressure.  The real question is duty cycle.  If you're nailing every few seconds then you'll need a compressor capable of keeping up with the volume of air being consumed OR you'll have to slow down until your compressor stops running before firing the next nail.  I run mine on 2 different compressors and don't have any issues- one is a 40 gallon shop compressor- the CFM is infinite compared to the gun.  The other compressor is 2.6 CFM.  I don't rapid fire when I'm using it and I can fire several nails before the compressor has to cycle.  As long as you're not continuing to fire when the compressor is running you should be OK.

**Q: How come just below the nailer specs they say "often bought with this product"....22 degree nails....not 21?**
A: I used some of the 22 degree without a problem. I've used Bostich guns for 30 years prior to this gun & this is as good as any I've used.t's a great nailer

**Q: will it take any brand of nails?**
A: I have used two different brands so far. As long as the nails are plastic coated, 21 degree I believe any brand would work. The best prices I have found on nails is at harbor freight. 2500 nails for around $28. I have used 2 1/2" and 3 1/2"

**Q: do the nails have to be plastic coated**
A: Plastic coated?  No.  But I do believe they have to be Plastic Collated, that is, they need to be bound together with plastic.  I'm not sure if paper collated nails will work.

### ⭐⭐⭐⭐ Works for me, and suggestion for bag
*by R***0 on November 9, 2025*

After decades of occasional use my old Hilti nailer died, and I looked around for a replacement. I got this one and am entirely satisfied. I don't have a way to tell if this would last for ages, but it works well, seems solid enough, and it was ridiculously cheap - and that's before the screaming Amazon day deal I got on it. It feels a bit heavier than my old one, and rather bulkier, too, but I can live with that for the price, and it's probably a function of more modern safety standards, anyway. As is the way with all nailers, as far as I can tell, they don't come with any sort of case or bag. I have no idea why. I like to keep my tools neatly and like to have a bit of extra room to carry around tools, spares and a few strips of nails. There seems to be no such thing as a blow-molded case for nailers. I'd have thought that there ought to be a market for such a thing, but I couldn't find one. Anyway, I got this carry bag: https://www.amazon.com/dp/B0CPHRJK5K , and am well pleased with the result. It fits this nailer just fine.
