What are the dimensions of the barrel but?
Vsuarez on Jul 5, 2019
Are most or all of these parts necessary for an at build?
Eric K on Nov 25, 2018
BEST ANSWER: That kit is needed if your AR upper has a “forward assist” for the bolt. If you have a “slick side” upper then you don’t need all those parts.
will this barrel nut work with a free floating hand guard ?
jeff m on Apr 6, 2020
BEST ANSWER: The simple answer is it should, but some free float handguards use a proprietary nut. If that is the case, it is usually provided with the handguard.

Best buy ever
Ok under the circumstance of covid 19.its been relatively relaxing to build ar uppers. Good quality and workmanship in the materials.has nothing to do with the covid 19 virus but gives me solitude to do the things i live doing.

Good to go kit, seems to be well made and right price point
Good to go kit, seems to be well made, all the parts are there to get your upper going and at a good price point, I rely on the Palmetto's parts to be able to build rifles I can afford but also that are just as reliable as the expensive "name brand makers" gun parts.

PSA products are matching function and looks of my high end components without the high end price! Would recommend.

Perfect, just what is needed
Good parts, delta ring is properly holding my mid-length furniture, forward assist is fine. Ejection port cover paint seems a little funny on the inside, but usually covered with a little oil, so not really noticeable. Don't drop the C-clip. Barrel nut threads are nice and smooth, no trouble when torquing.
