Yea that's the kit I got only it came with two magazines for a little less money.
Not satisfied with the way the magazines lock the bolt back on the last round or the increased hassle of loading ammo, (really not that bad) I got a BETTER-MAG adapter that allows me to use the S&W M&P 15-22 magazines which I much prefer.
Also got a plug for the buffer tube. (not necessary)
Now Rambo here has 110 rounds loaded up to suppress the plastic bottle onslaught! 😎
ETA: After a few hiccups when first used, which I attribute to a break-in period, this kit is running 100% now.
