Tuning Barrel support umarex gauntlet

[Rawroots]

I guess I was just bored, I looked up a price on a aftermarket barrel support to try on my gauntlet, it would put pellet on pellet at two different locations on the target, didn't want to spend 30+ so this is it and it got dark out too fast to try it out today, does anybody else do this kind of stuff ?

Looks like that may work.

Looks good. I have a the barrel band that goes around the regulator and it still shoots two groups sometimes. Ive found a NSA slug that doesnt do it, but basically every pellet shoots 8 in one spot and 2 low ones.

ALSO! Check to see that your shroud barrel centering bushing is not cracked or wobbly or loose.

Lots of info on the barrel support issue on hajimoto website. I have just started modding my gauntlet, and I haven’t pressurized it yet.

Buy yourself an easy to operate, fully assembled 3D printer like the QIDI X-one2 and you can make things thinner and stronger. If you don't know CAD design you can start simple and free with tinkercad.com

Here's a bottle band I printed with a split picatinny rail to mount a bipod on my impact and an improved air stripper I designed for my son's gauntlet to make it much quieter.

... and the gauntled modified for a 300 bar cf bottle.

Interesting that top shooters, both air and powder, utilize free floating barrels in most instances.

Powder burner barrels are thick and threaded into the receiver so that’s that. Top shooter airgun guys sight their gun in every time they pull it out of the case right before they compete because their free floated barrels won’t maintain POI day to day. The rest of us like to grab our gun anytime we want and hit stuff. Thus supports or tensioning becomes avenues worth exploring.

Just moving a gauntlet into a case and out will throw off the POI by inches without a barrel band. The shroud is so long and flimsy that it bends and moves the barrel if you just breath on it hard. The heavy spring that pushes against the baffles/stripper just make it even more prone to POI shift if the shroud is unsupported... if you grab your shroud and give it a 1/4" turn, you'll see your POI go off by several inches at 50yd. If you just shoot paper and sight in every time you go to the range, I guess its not an issue. 

Current production gauntlets (22 and 25) come with a barrel band from factory.

Some guns shoot more accurate with barrel bands while others not so much even twin guns same manufacture and caliber.

Example I got two 177 Gauntlets and both about the same accuracy but one shoots a flier every once in a while without a barrel band same with a pair of BSA Bucaneers and Gamo Urbans one with and one without. Benjamin Discovery and Maximus couple improved with added additional barrel bands. All guns take barrel bands different depends on harmonics too. I own multiples of almost everything in the same calibers and witnessed.this first hand.

Moat of my most accurate 300+ yard PCP guns have factory barrel bands and aren't even regulated. Couldn't leave a couple of perfect shooting guns alone so had AZ add a regulator to one and could no longer get the 300 yard accuracy So Sold it because I didn't want to only limit myself to 100 yard shooting. Learned the hard way to just leave perfect shooting guns alone.

Flip side he yanked an FX 500 reg to run it unregulated and that one is the most accurate long distance shooting FX 500 I own that is no longer regulated.

@heavy-impact How many iterations did you print before printing the part that worked the way you wanted it to?
