Am a little late on the reply, forgot where this post was lol, the breech is made by Sergio his company name is called BNM, Heres a link to his website where he sells his breeches and other custom parts, Everything he makes is mostly for crossman, discovery and marauder guns.

Here is my build so far, need high scope mounts to bring the scope forward more, a nicer looking muzzle brake would be nice, possible i might get a new trigger frame for attaching the AR15 grips, then hpa line or bottle attachment or i might just go the hi pac route .. :smile:

i use this same setup with the dummy powerlet and macro connections on a few of my full auto pistols. there is 1/4" and 1/8" and i do not think there is any difference in the flow at all. i used 1/4" on daisy 2003 and can empty a magazine with no noticable loss in velocity. so i used 1/8" line on wather ppk to simplify installation on smaller gun, and it works just as well. another case in point is paintball guns, a lot of paint markers have very thin macro line running on outside of gun to get co2 from the valve at back of gun to front where paintball chamber is. just keep the length as short as possible.

help with HPA macro line fitting for custom 2250 build, OD ID?

Hi guys am in the middle of a custom Crossman 2250B build. Right now am looking to attach a stainless steel macro line to a Brass powerlet Eliminator from Euro Custom parts, I was sourcing a macro line locally and they build them any way I want them, they specialize in these fittings so, I was wondering if anyone here has some experience with 1/8 NPT fittings ect

My question about these macrolines is that of size, as in the ID OD of the macro line itself, well since they build them they asked me what size I would need, since I never really thought about it and thought it was a standard size thing, I need to know if it matters about the OD, ID or if a bigger or smaller OD ID is better or worse or what the optimum size would be ... air flow????

The macro line is going to be 12" it will be a direct line from the powerlet adapter after a 90 1/8 elbow fitting then to a Double End Female 1/8 NPT to a quick release nipple then i was going to to hook up a remote line to that under the grip .. i might do the asa adapter thing with a direct mount but for now this is the plan

Also would it be better to have a Non Return Fill Quick Release Nipple 1/8 NPT at the end or just a reg quick release nipple ?

my remote line has a slide check ...


Basic Config:

Powerlet > 90 Elbow > Macroline > Double End Female Adapter > Quick Release Nipple

Also I should mention they asked me what PSI rated line I would like to use? they have ones that are standard 3000psi rated then they have a more premium line that can withstand 3500 psi .. does it really matter?

I will be running 1200psi HPA for now then later a 1400-1500psi
