Smooth, reliable operation at a reasonable price
I've owned several straight-blowback PCCs and was less than impressed with all of them. I had pretty much given up on the concept, and the alternatives (MP5, MPX) were just way too expesive. I had seen the CMMG RDB setups, but didnt believe that it could possibly make that much difference. I was wrong.
<br>I decided out of a lack of other options to give this a try. I bought this 16" barrel and bolt kit, and built them into an Aero Precision XL upper. What I ended up with was a light, handy rifle that is incredibly smooth and soft shooting. I have about 500 rounds through it now, using one of the cmmg 9mm conversion pmags, and it has been 100% reliable. It's everything I was looking for that the straight blowback guns weren't, at less than half the price of an mpx or mp5.
This is Cool !!!
I purchased this for almost a year now and built my upper... No problem at all......Thanks
