What I did get was a box of goodies from Mathew Bean, he supplies HPA upgrade stuff to the airgun folks. I also bought one of those "colored" 850 stocks that UMAREX was offering last week.... but got mine in Grey :-P Anyhow, I picked one of my 177 850's and converted it to HPA. Thats a 22ci 3000psi tank with 1200psi regulator on it. Should be good for 120 shots at around 900fps. Now all I need is some air Roald.   Posted: Sun Mar 16, 2008 4:55 pm AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6908 Location: "Out There" Lookin' good. What parts are in the 850 now- and approximate cost? _________________ ` I'd say "I care." But I'd be lying.

I still have ot get a Scuba tank though, so add another $200   Posted: Sun Mar 16, 2008 5:09 pm AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6908 Location: "Out There" $90 for the tank and regulator is alot better than I was expecting- Umarex wanted something like $200 for a replacement tank for the Dominator 1250- which was smaller and I don't believe a regulator was part of it. So- how do people find Matthew Bean if they want to go with a conversion like this? And definitely let us know how it shoots after the conversion and a realistic number of shots with that reservoir on the gun! Curiosity is killing me. _________________ ` I'd say "I care."

Roald.   Posted: Mon Mar 17, 2008 12:34 pm StevieLaner7777 Moderator Joined: 07 Mar 2007 Posts: 1060 Location: Herefordshire, UK Looks really nice Roald, The tank doesn't look too much out of proportion either, fits in well with the rest of the 850's features! Just need to clean the edges of the hole that the gauge comes though and jobs a good un!

Stevie, I was so excited that everything lined up I took the pic before it was finished I had to get my 24mm socket back before I could finish the hole.... It's all smooth and clean now. I'm ordering a 3300psi scuba tank tonight. I can't afford those 4500psi tanks and also have no place locally to fill one.... I converted one of my 850's to HPA today...     Air Gun Home Forum Index » Rifles You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum All times are GMT - 5 Hours   Page 1 of 1   All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First  Select a forum Main Forums----------------AirGunHome Q&AGeneral Air Gun Questions and TopicsPicture GalleryTarget Shooting: Casual, Fun and CompetitionHunting, Pest Control, Varminting People/Events/Airgun Issue Discussion----------------Introduce YourselfThe BS TopicClubs/Events/Regional/Political Airgun Issues Maintenance, Modification and Reviews----------------RiflesPistolsAntique, Collector and Novelty AirgunsBB GunsPellets/AmmoOpticsAccessoriesAirgun Smithing Buy, Sell or Trade Forums----------------For SaleWant to Buy   Note: If you are seeing "Please enter your username and password to log in."
