Is it worth it? Any experience with this lower

[Mutt]

Yes, it's worth it. The actual company is Surplus Arms and Ammo. I buy all my uppers and lowers from there. They are built really well and the specs are dead on. They have a nice snug fit. Both lowers I bought from them had really crisp 3.8 pound trigger pulls. The company is only 20 miles from me, so I've checked them out really well. You won't be dissapointed with them. But, I wouldn't buy that one off of gun broker. Even though he says it's new. He bought it and now wants to sell it .... so it's used. Who knows what he tweaked and what he did to it. You can buy a new one from that company for the same price.

They have a reallly good reputation on Arfcom.

Here's the web site for the company http://www.surplusammoandarms.com/
