So most people don't find it worth the effort. Its alot of modding work just to get a comparatively small improvement.SG Nerfhttps://www.blogger.com/profile/03136329934823654372noreply@blogger.comtag:blogger.com,1999:blog-2872518359543654640.post-32692821009374093772015-11-29T20:10:01.427+08:002015-11-29T20:10:01.427+08:00Does this work on a longstrike too?Does this work on a longstrike too?Anonymoushttps://www.blogger.com/profile/17935424844034727670noreply@blogger.comtag:blogger.com,1999:blog-2872518359543654640.post-62953077810982195222013-09-05T17:31:28.355+08:002013-09-05T17:31:28.355+08:00Anonymous,
The short 17/32" and 9/16" ...Anonymous, <br /><br />The short 17/32" and 9/16" brass pieces are meant to be spacers to allow a double layer of gap so that the half-pipe on the barrel side can slide into it... if they were longer, they would block the barrel half-pipe and the breech will not be able to close.<br /><br />That being said, it is possible to extend the length of the 17/32" brass piece (but still leave the 9/16" brass piece short), though that tends to cause issue with friction as the single layer of gap can become too tight and cause jams, unless both the bolt and barrel are constantly 100% perfectly aligned (which is rarely the case).<br /><br />So its recommended to allow a double layer of gap to allow for more leeway and smoother parts movement.SG Nerfhttps://www.blogger.com/profile/03136329934823654372noreply@blogger.comtag:blogger.com,1999:blog-2872518359543654640.post-1276157053591848612013-09-05T13:42:40.779+08:002013-09-05T13:42:40.779+08:00Sorry for the lateness of this post, but I've ...Sorry for the lateness of this post, but I've only recently gotten into modding my Merf blasters and found your great guide.

Its amazingly helpful in my understanding of this mod.)<br /><br />I'm about to start doing the brass breech for my Longshot and wanted to know why only 2cm for the 17/32" and 9/16" brass pieces? Wouldn't having those sections longer, say to just before the end of the 1/2" dart pusher piece, be more stable and provide better support for the bolt? Or is there a specific reason they are that length?<br /><br />Thanks in advance for your help and again for making this awesome guide!!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2872518359543654640.post-60566357811224120702013-07-27T14:11:14.535+08:002013-07-27T14:11:14.535+08:00matamata,

The step that I am unsure of is Step 8. In particular how far along the bolt to place the plastic attachment tip.<br /><br />I have assembled the parts to attempt to find the maximum forwards and backwards movement. It seems that the orange attachment piece should be lined up with the end of the brass bolt, however looking at some of your images it seems to be set back more.<br /><br />It also seems that I will be able to slide the bolt into the plunger tube all the way in until it reaches the attachment point, effectively meaning I should whittle the full length of the segment of plastic behind the attachment point.<br /><br />Can you provide a measurement for where the attachment piece should be connected to the bolt? Is it flush to the end or is there a problem with lining it up flush to the end? <br /><br />I am planning to glue it flush to the end but I don't want to position it incorrectly as it seems to be a critical step.Slapnoreply@blogger.comtag:blogger.com,1999:blog-2872518359543654640.post-2571908040565361512012-12-30T15:50:26.293+08:002012-12-30T15:50:26.293+08:00Rob,

I bought a longshot from craigslist that I got screwed over on, the internals are not happy and the O ring is shot.<br /><br />IF I had to replace the plunger tube, I was thinking I might make it longer to push more air, seem reasonable?<br /><br />But the real question is about stephans, I looked at the angel breach design and found his write up hard to follow. Would I easily be able to change your design by shortening the dart entry area? or Could I just use your design as is and shoot elite darts or stephans depending on whats at hand? My kids use regular darts, so we have a lot of them available at the house, but I would hate to be at a nerf war and unable to reload off the ammo shot at me.<br /><br />This post is a thing of beauty, easily followed and comprehensive.<br /><br />When finished my gun "Frankenstein" will have a dual machine gun integrated front gun, thanks to some spare parts from some stryfes and auto tommy 20s, I am very excited to add this to the project, as I had come up empty on a "rebuild" kit for the longshot :)Robnoreply@blogger.comtag:blogger.com,1999:blog-2872518359543654640.post-35175601999009012912012-11-24T18:12:12.570+08:002012-11-24T18:12:12.570+08:00Anonymous,
