This product truly lives up to the hype i have been reading about. the firepower produced by this frame is mazing i took it out on the field two days after i got it and i took out 2 cockers and 1 shocker with little effort. in short this gives you an edge right out of the box. puts out a great tight pattern too. my trigger pull is less than an inch! its great for speedball and for spray and pray! well worth the money.
nothing really except adds alittle extra weight to the gun.
i very much recommend this product to piranha owners its very much worth the money. plus it doubles the value of your gun! theres nothing like it on the market for piranha owners. but shop around and find a good deal first. i got mine for $217.95 total when its usualy 250$ with out tax so look around.
