PSA AR10 builders set for sale. I've got a lightly used PSA PA10 upper that I'd like to sell. Includes: - Upper with forward assist and ejection cover - 15" MLOK handguard w/ barrel nut Great condition. Finish out that build! $220 cash for all. If you want to break things up, it would shake out as follows: $120 for handguard $120 for upper A nice discount for picking it all up... saves me time and saves you money!
