The HSW IFrame is by far the best trigger/frame upgrade that u can do to your impulse. The trigger pull on mine is so short that i can barely even feel it move when i pull it. The trigger is so light that you dont even need the trigger spring so i just took mine out and now my trigger is so sensitive that i can shake my gun and it will shoot. This thing is fast, faster than any other trigger ive ever used. It increase my BPS by at least 3. I did alot of debating on whether or not i should get this product because it was so expensive, but finally i bought it and ive never been happier. $150 is a small price to pay for the performance you get out of the Iframe. This trigger frame feels absolutely great. The back end of it is rounded so it fits to the shape of your hand perfectly making it much easier to keep a steady high ROF going. The only weakness i could find was that the Iframe moves the trigger frame so far foward that it touches the elbow for the macroline this can be solved by just twisting your regulator 1/3 turn in either direction. Another problem may be that you can't wrap your hands completely around the reg which some people like to do. But this is easily fixed by buying a NDZ 15* ASA.
This is probably in the top 5 best upgrades you can give your impulse after vision, a barrel kit, and new internals. Anyone looking to take their game to the next level should deffinately buy this product. It's well worth the money and once you decide to shell out the money for it, i promise that you will not regret it.
