Best Budget Lower Receiver

Review by James on 16 Jun 2025 review stating Best Budget Lower Receiver
Ordered again, this time 3. It's just that good. Perfect tolerances, Milspec to the core. I built 6 with this lower and so far it just runs flawless. Talk about High Quality Budget builds, this is the one! Will buy more in the future! Also Rainier Arms is the best, just wish they can overstock on a lot of items.

Top 1X Prism

Review by Chris A. on 11 Jun 2025 review stating Top 1X Prism
For the money you pay, you wont beat this beast. Crystal clear, large sight picture, and holds zero reeeaaalll nice. As long as you aren’t a potato, you’ll hit everything you aim at with it within 100yards, and I was constantly on steel (12in x 12in) with it at 200yards.

Lifetime warranty? Are you kidding?

Just run this, and thank me later.

Also, Rainer Arms, can’t go wrong with this great company.
