Thoughts on converting a (c02)GBBR into firing .177 steel BB's?

[Activist]

I'm a chairsofter so I only participate in range/target shooting with the occasional use of magpie pest control.. So other than shooting targets on my acreage I don't ever participate in airsoft events or ever use them to shoot at people.. So please don't get the wrong idea about this topic as it's not about making a more deadlier and unsafe airsoft weapon..

I'm wondering if it's at all possible or if anyone has ever attempted such a thing before? I realize the biggest issue would likely be the magazine, the gas valves/pressure regulators, and fitting in a small calibre barrel where the 6mm barrel previously fit.

If anyone has tried anything like this before then please post and let me hear about it! I think it would be great if I could convert a WE open-bolt GBBR to fire metal BB's with it's c02 charged magazine system. I currently own an automatic BB gun made by Umarex called the "Steel Force" 'AR-styled' BB gun that fires semi auto and a 6-shot burst as fast as you can pull the trigger (which essentially makes it fully automatic - however I've seen youtube video's on how to take out a gear within the main housing of the internals which removes the limited 6-round burst).

My Steel Force recently broke down due to an internal trigger mechanism failure from use... So I've not got a .177 barrel that is long enough to work inside of a short-barreled/commando styled AR weapon so I'm wondering if it's possible to fit it in and line it up with the feeding path of the 6mm bb's; except I would of course have figured out by then how to situate the modified magazine to the feeding path leading to the chamber/barrel.

Why not just use the 0.88g steel bbs? 15/64" steel ball bearings

Would those weight more or less than standard .177 BB's? 0.88g would be more right? And are they steel all the way through or are they metal-coated plastic BB's?

Could be done, but you'd likely need to modify the mags, the Hop-up wouldn't work worth a damn, you'd have to increase pressure and change out barrel types. You'd be far better off buying a gun already equipt to do that. They do sell some nice ones out there.

What about converting a c02 powered GBBP?

Why not just buy a .177 GBB, theyre actually cheaper than airsoft.

Same problems. CO2 Metal BB guns exist in quantity and variety...

With the work of the conversion, you'd be better off buying a pellet gun.

You would need to modify the mags with
-narrower springs
-narrower follower
-different feed lip
-narrower BB guide

On the gun you would need
-new barrel
-new hop up unit
-new hop up rubber
-new nozzle
-new loading ramp

Not worth the effort.

Short answer:

If you need to ask, you don't have the knowledge, tools or means to do the conversion.

[Activist]

I ask because there are no gbbr's in existence that fire 177 bbs. Certainly none with blow back.

As for the gbb 177 bb guns - there is no realistic gbb replica of a s&w m&p.

If the guns I want to convert already existed in 177 then obviously I'd buy that then.. Come on guys

I'm not concerned with the hop up. And are you sure about a new loading ramp? It seems smaller bbs shouldn't have too much issue loading on a ramp that's slightly bigger..if it were too small then I suppose a new loading ramp would be necessary..

Also - for the record as for not being worth the time or effort - this is no issue. Let me worry about that

It will jam, 100% of the time.
The feeding notch on the nozzle will jam the BB on the ramps because it's allowed to slide/roll over it.

There is a reason why there are no pellet/BB gun that replicate real weapons accurately: They are weapons, and the companies would be liable to be sued by the real weapon manufacturer.

Check the ASG line of .177 pistols.
Almost all of them are blowback and CO2.

Thanks for the input! Appreciated

Do you want to get jams and broken nozzles? Because that's how you get jams and broken nozzles.
