Does this wrench work for the PSA AR10 308 barrel nut?
Jim S on Jun 12, 2019
Does this tool have a 1 1/8' Free Float Hand Guard Nut Wrench?
Michael H on May 27, 2019
Is there any difference between the PSA & Mapul’s armorer’s wrench?
Sandoval247 on Jun 2, 2019
BEST ANSWER: They are similar but different. The buffer tube wrench is fully enclosed on the magpul but not on the PSA. The PSA is very good for the money
Can I use this on a PA10?

Does this tool work to install and remove the Hogue 2 piece free float ar15 handguard nut? There is littlexspace between the receiver and the nut. Thank you

Great tool. A necessity for AR assembly.
Heavy and well made tool. Made assembly even easier.

Heavy duty
This is heavy, as in made of metal, and great quality for long-term use around the shop.

Very nice tool, built great! Bought 2, could probably build 1000 guns with both before having to replace.

Some modification/adjustment required
I'm not sure if my wrench slipped past quality control or what, but i'm 0/2 on the things I specifically bought this wrench for.

1) The paint coating appears to have gone on too thick for the buffer-tube castle nut teeth. I bought the complete lower parts kit directly from PSA, and this wrench doesn't fit their own product. I've been sanding down the teeth trying to get them to grab a bit better.

2) The open-ended fork is similarly just a bit too tight (a few mm off) for my SLR rifleworks handguard. I've sanded things down, but the barrel nut is still just barely too big to allow the mouth of the wrench to firmly rest on the flat parts of the barrel nut - so that I can tighten things down all the way.

Super let down and going to have to work the wrench over with a metal file so that I can get it to do what I need.

Great tool
Very solid and well finished. Looks like it will last a lifetime. Similar tools cost $75... this one was $24.99. If I'm looking for something AR15 related, PSA is my first stop and usually has what I'm looking for. Stay great, PSA.

Great value
Very solid, much heavier than I expected. Used it to rebarrel 1 upper so far. I like having a 1/2 drive slot in 2 spots. Works as advertised and for the money I like it a LOT more than the tapco offering

Great build tool for the price you can’t go wrong!
I needed a new armorers tool and saw that PSA had one out and wanted to give it a go. Great tool well built and well balanced. Highly recommend
