Yes, polymer 80 lowers are quite good. Our customers have loved them for quite a few reasons: They’re more affordable than metal lowers and jigs. They’re easier to machine and build with. They’re capable of taking some real abuse, as any good AR should.
Are polymer lowers strong?
The Durability Issue The biggest question people have with polymer AR lowers isn’t usually the fit of the product, it’s the durability. If a polymer lower was going to fail, it would be there. While the recoil of a . 223 Rem/5.56 NATO is minimal, that part of the lower still bears a significant physical load.
What is a KP 15?
The KP-15 is a monolithic polymer AR15 style receiver made from injection molded 30% glass filled nylon incorporating the buttstock, buffer tube, pistol grip, and trigger into the receiver design as integral components. This manufacturing process offers several advantages.
Are polymer lowers as good as aluminum?
It’s easier to make unique lowers from polymer and poly lower receivers are often much cheaper than aluminum receivers. They are quite light as well and are the most affordable lightweight material on the market.
What is stronger aluminum or polymer?
Generally, steel is stronger than aluminum, which is stronger than polymer.
Which is better polymer or aluminum?
Aluminum receivers are going to withstand wear and tear better than their polymer equivalents will. They have higher melting points, don’t warp or flex under pressure, and can be dropped without fear of cracks or chipping.
What does ke stand for in Ke arms?
KE Arms, short for Kenney Enterprises was born in 2012 when owner Mike Kenney realized the demand for ARs outweighed the supply by a large margin. Coming from manufacturing hi-end automobile parts, KE was able to jump into the firearms industry with much success.
Are polymer lowers lighter?
Polymer parts will nearly always weigh less than their metal counterparts, receivers especially. The average polymer receiver weighs around one pound, while aluminum receivers weigh about twice that.
What is a polymer lower made of?
It is made from a “high-impact composite polymer” and the claim that it “bounces back to shape” when most lowers bend or break is not an exaggeration.
