The Beeman 1085 breech on a umarex gauntlet?

[antithesis]

I have been studying the QB basic design and variants inside and out as of late attempting to familiarize myself as much as possible for my present gauntlet build.

As I was attempting to remove the bolt for polishing of the internals and breech, the hex key broke and left me to need a replacement.   And umarex apparently don't play that game 🙄

I have been looking into getting a refurbished parts gun, when I happened across the Beeman 1085. As far as I can tell, this breech is a more streamlined version of the gauntlet breech complete with rear sight if desired .  I can't confirm complete compatibility but I have two concerns before purchasing

1. No recess provision for the shroud, a little ingenuity will cure that

2. Location of barrel set screw holes

Does anyone own one of these or are familiar enough with the anatomy to know whether this idea is feasible? Because it cures my hunt for a breech more cheaply and it DEFINITELY looks way better, despite a bit less room for mounted optics

apparently the beeman 1085 is yet another repeater variant of the qb78.

That was among the articles I had perused trying to get a better look to determine if I could buy one to do some parts swapping. I may or may not have to decide on the magazine type id rather use, I think you can pull out the retainer pin from the 1085 breech and use the gauntlet/ mrod style mags ... though I do like the idea of the pin being there honestly

HAve a 1085...don't have a Gauntlet to test the theory.

RS,

does the rest of the gun,  meaning the tube and action, appear standard QB?   And for that matter how do you like it as it is? I wouldn't mind having  a little summertime synthetic plinker.. I just didn't want to buy another refurb gauntlet just cuz I can't get parts from umarex

[scion19801]

Antithesis,
why can't you get parts from umarex? every time is e-mail them i get prices and a way to get the parts i'm looking for from them. I haven't tried since the Virus ordeal. But i do know that i was looking to get the valve, .22 cal barrel and bolt and there didn't seem to be an issue.

I needed a breech and then a second shroud tube, dealt with 2 different people. Maybe I need the wrong parts but it seems to me all the bigger parts go toward the refurbs.  I even got a price on a breech assembly and he said if have to buy a USED one WHEN it comes in. My experience hasn't been so easy thus far

EDIT: actually a main tube too.... thought for sure that would be in stock but I ended up ordering a QB 78 tube to cut down myself

[Ribbonstone]

Haven't tired it...have compared it with a standard QB78,and it looks like it would fit but have not actually swapped tubes.   So it's just an assumtion at this point.

Only problem is the stock.  Not only that it's ugly, but the higher breech really makes for nothing to cheek....basically a "chin rest".    QB wood stocks will fit (have to deal with the odd barrel band), but the same lack of cheek height.

And there is the gauntlet... It isn't my idea of an attractive gun but they give you the adjustable comb.... but if I put the 1085 breech on I have a feeling I'm going to have eye releif problems without a rail extension of some kind....that cut angle at the rear of the breech coupled with the lower price is what prompted me to consider it in the first place, it'd definitely look better than the blocky gauntlet breech but then, form follows function sooo....idk

Working on it...give me a 1/2 hour or so.

RS,

Working on what? Lol don't go stripping your stuff down for the sake of my curiosity

i didn't care for how wobbly the cheek riser was on my gauntlet when fully extended so i got a small piece of kydex and custom molded an extension for excellent cheek weld. i use the fx no-limit rings. i attached the kydex to the cheek riser with heavy duty outdoor use velcro.

You know I understand that the rear sling stud is supposed to lock the riser in place. Not sure if you knew about that alot of people don't apparently.. ..I'll likely look for an optic I'm happy with , adjust the comb accordingly, and probably fill the space with some sort o structural epoxy or similar, bonus points if I can find something to function as a mold release and make it removable incase I ever sell..... although with all the time and money I'm putting in this rifle I don't think I'll ever sell lol

rear sling stud only locks the wheel in place so it doesn't move. there was still too much wobble for my liking to keep a consistent placement. $10 fix with a small piece of kydex custom molded and velcro. even have enough kydex for another one, as i only used half the sheet i got.

Kydex does sound like a good choice of material, though personally I've never worked with it. And having a hard time imagining how to start making what you did, sounds like it took some patience 🤪

I'll write it up as a separate post....but for now,just the results (no pictures).

No problem taking it back apart....I just did that, and haven't sighted it in yet, so no-harm/no foul.

Realized I didn't need to take apart a functioning QB78 (co2/HPA/PCP) to find out if a 1085 breech would fit....could just see if a junk-box QB78 breech would fit and work on a 1085.  If it works one way, would work the other.


For sure,can fit a QB 78 breech/bolt system to a Beeman 1085 but you'd have to adapt some parts.

How that relates to a Gauntlet (that I don't have), can't tell you.

Seperate post to follow.

Does the adaption aspect have to do with the rearward cocking/multishot conversion?

I don't myself yet own any actual QB / Beeman branded guns but by all accounts the gauntlet is a multishot, regulated shrouded hpa variant of a QB, I measured an 11" tube. And I think the bottle block is different as well as it not needing a conversion kit to adapt a multishot, cock on opening breech

all you need is some patience and a heat gun. it's heat moldable. I used a piece of 1-1/4" wooden dowel rod(closet rod) as a rounded form for the top rounded edge. then use a saw and sandpaper to follow the same basic lines of the original cheek riser at the bottom edge. tried to keep the kydex wrapped almost completely around so both side touch on the dowel rod. i'll try to get a rear view pic of what the kydex riser looks like.

Ohhhh I'm getting a better idea of what you did now.   Actually that's pretty cool, I have to get this girl up and running and once that's done I am definitely keeping this in mind, although I seldom have cheek weld problems I don't like wobbly cheesy things either 🙄

Good thinking

[scion19801]

i did have to send the gun back to umarex for barrel warranty and it had the velcro stirps on the riser. they gave me no issues what so ever about things being modified. i've heard some makers would not honor warranty work when mods are done.
