| Hello all, I am new to this forum. I recently bought a Smith & Wesson m&p Sport rifle. I am looking into to modification parts and I can across a polymer lower. I am guessing this is just to make the gun lighter. Would you buy this for anything else? Are there any advantages/drawbacks to this lower? |

Depending the lower mfg you may want to run away from the polymer lowers..
google ar-15 polymer lowers and you will see a LOT of pics of busted ones.. typically they break where the stock attaches to the lower The exception to run in polymer lowers is the GWACS Cavalier Mk II - the stock is built in as part of the lower and I have not heard any saying they broke theirs..

Brian Here's and observation about the Cav15 lower: since the stock, grip, and buffer tube are integrated, the weight savings is distributed across the entire lower. This differs from using a standard poly lower, where you still have a big chunk of weight on the back in the form of a standard buffer tube and stock. |
