I saw this RAP4 Smart Parts SP1 6 Inch Super CQB Recon Barrel and absolutely loved the look. Has anyone used this, or know if it is crap. I am running a stock barrel as is.

Don't believe the whole lands and grooves marketing, but overall it isn't a horrible barrel. It isn't a great barrel either. They don't provide a specific bore size so their consistency isn't likely top notch. 6 inches is a bit on the shorter side so you may notice a drop in air efficiency. On the bright side its all unported, so all 6 inches get used to propel the ball. For the price it's a fair deal, but I would suggest spending just a bit for and getting a once piece CP barrel. I definitely wouldn't buy it for its looks.

i wouldnt waste ur money, lapco bigshot 8 inch.
or if you want lil length cant go wrong with cp, or dye ul.

I second what Mamba said.

special ops C seires four inch stiffi with devastator tip. thats what I run on my cqb barrell, its a little shorter than that and, its lighter, better, you can put an apex on it, all around better IMO.
