I finally got my G7 Dezign's bolt today and wanted to give my 2 cents so here goes. First off i placed my order last week around monday/tuesday and i got my bolt today (wednesday). It came in a simple package with 2 dezign stickers, which are always nice. My version is the open-face design. Here's a breakdown

Quality: When i first held it and looked at it i was truly amazed how perfect this bolt looked. it was hard to believe a person made it since the measurements and smoothness are so perfect. There werent scratches or little knicks here and there that would be a giveaway that this is a custom job. If i were to glance at this bolt without knowin wat is was than i would definitely guess it was a mass production bolt. Needless to say im very impressed.

Performance: First off i shot my fly g7 with the stock bolt. conditions were as follows. Temperature is roughly 50 degrees, paint was low/mid grade, dwell 10, lpr 50-55, tr 22, reloader b on setting 1. and away i go. First string of balls shot perfect, paused shots another string, and BAM, barrel break. Cleaned out the entire barrel and other spots that got paint on it and tried again. First couple shots were good then BAM, another barrel break. Cleaned out the gun and on to the Dezign's bolt. Everything else is constant, no settings changed. Shot a string, all was good, shot another string, still good, then i let it rip. hopper emptied, barrel clean =). Anyway, i decide to push my luck, and i set the reloader b to the fastest setting, which most people know is suicide for bad paint in the cold. Here goes, ripped a string, perfect again, ripped another and still sweet music to my ears. Then i decided to let it all rip and empty the hopper, one break occured BUT it was after the ball already left the barrel, so barrel is still squeeky clean.

For those concerned with rollback: being open face sure there will be room for the ball to fall into the bolt, but after testing it out i found that it wasnt enough for a second ball to peak through. so let not your heart be troubled.

As for velocity, i dont have access to a chrono at home so i couldnt tell if there was an FPS increase.

Overview: i don't wanna jump to conclusions just yet as to why i got so many barrel breaks, but so far i am very satisfied with my bolt. i believe that the open face design offers a better flow and due to the conforming of the balls shape, results in a bit more gentle on bad/brittle paint. Sure it is $65 a bolt, but from my experience so far, the stop in paint breakage is worth every penny.

Pics:(sorry for the quality)

Really nice review bro...But I'm interested in the difference in perfomrance between the open face and venturi styles....If someone could shed some light.

Correct me if I'm wrong but El P, don't you use a ventri style? Do you think there would be a big diff in terms of performance???

Haven't heard from you in a while so it would be nice to get your imput.

nu cut-outs for the ball-detents like on stock bolt ?

I tried peeking for it but it seems to be missing ?

Would this cause more wear on those with long term useage ? :)

As always well written, but as you put in too, a chrono would have been great :)

I too tried the DEZign G7 bolt. Didn't have a problem with it but I did not see an increase in velocity at the same operating (minireg) pressure. In fact, the open face G7 bolt that I tested has the same internal volume as the stock G7 soft face bolt.

I also saw no change in barrel breaks because I was not getting them at the time when comparing either bolt so to be fair I cannot comment on barrel break reduction.

I was hoping to see a increase in velocity but I did not so I simply went back to the stock G7 soft face bolt and never looked back.

That is not to say they might not have changed the design since I tested one out. They could have since they are custom made one at a time.

But, YES the DEZign bolt are extremely well made.

The potential for roll back still kinda concerned me too.

i was worried about the roll back too but after looking at how much roll back there was and looking down the breech, im no longer worried about a ball being pinched as you can see

Cool. Again, I want to be fair and say that I am not saying that I got chopping due to the open face bolt roll back. It just bothered me a little because it looked so significant and I chose not to go away from the original G7 bolt set-up. It was just personal preference on my part.

that looks like a significant difference to me

significant that u can see yes, significant to affect performance? nope. as i pointed out before, almost every high end gun has the same amount of rollback since most people use venturi/open face.(examples: ego/trix/shocker/dm)

id still love to see a venturi review too :)

And .. again .. no cut-outs for the balldetents on the DEZign bolt ?

nope, but its not a problems, theg7 detents arent that stiff to cause significant wear. just think about the a4 bolts...when was the last time u saw one with dented sides? =P
