I have the model m&p15x that I bought new back in 2009. Its has been & still is a great rifle. I would go ahead & replace the buffer spring, its cheap & should be done every 3-5k rounds. With the carbine length gas system you can put a heavier buffer in also. I just switched my H buffer out for an H2 & it runs smoother & I haven't had any problems yet. I recently upgraded to a Geissele SD-E trigger & this 1 upgrade was the most noticeable improvement. From now on a trigger upgrade will be in my top 5 list of parts to replace. You should take a look at some of Bushnells red dot offerings, they are worth the money & depending on the model you could drop some weight off the top of your rifle. I run the BCM medium size latch on mine, not too big & not too small & plenty strong
