Umarex T4E HDR 68 75 Joules Zrams Juls HDB 68 Barrel 

Bruh you got a armory you need to send a spare a fan any of your works of art is definitely needed in my neck of the woods I'd just like to review one of your products even if I had to send it back lol...keep up the great work man you make awesome content

Once you get that barrel working 💯 you need to give 90g a spin. Should be interesting comparing 1100psi to the 90.

Iam using same set up but with90 gr co2.i like better more power.but costly but for home deffence a must.

Nice power💥. Great test 😃👍

Hello, I'm also in the process of having an HDR 68 HPA conversion. It was recommended that I remove the pressure regulation from the HDR. Do you have a video about it or can you tell me by email where the part is located so that I have full performance at 1100 psi? Many thanks. Greetings 

Complimenti 🎉🎉anche la mia do rebbe essere cosi potente forse piu,perche lavoro a 1200psi però se non riesco ad estrarre la valvola restrittore non posso usare hpa😢

I thought i heard you say a 12 millimeter maybe it was twrlve inches i heard but where did you find the barrel preferably the 68

Do they make sabots that can fit .25cal slugs for this gun? If your able to get that much energy and speed a plastic wad with a 60grain .25cal slug in the middle would fly pretty fast and have a lot more penetration. The thing with big rounds at such low energy is that they're not gana have more than 1-3inches of penetration at these levels of energy . A .25 slug with 60joules of energy is gana go 6-8inches deep, where as a 68cal ball or even a slug would only have like 1-3in of penetration and 75joules isn't enough energy to really knock down a tetermined attacker, that's like half as much energy as a 22short but without as much speed or penetration as the 22short since that energy is being concentrated into a smaller area allowing it to keep more inertial energy as it penetrates way past a 68cal of the same power level

Is there a way to keep that high 75joules power without a giant tank hanging off the gun? Like if there's one that sticks out 2-3in that's fine even if I only get 1 magazine a fill I plan on using some sabots and shoot 9mm slugs, and .308 slugs. They're light, more sleek, and penetrative. The regular sized barrel no mods hdr50 using sabot 9mm rounds added alot more power and speed to the slug. Devestator rounds would be dope to. I am in-between this or a AEA defender 2 .457 2shot over under multi cal pcp cartrdige pistol that gets 70-75fpe in a 8in barrel with 180g .45 slugs for $350 it can also shoot non lethals pepper spray arrows and shotgun loads. I just don't like the 2 shots before a reload. If I could get something like this gun u got without a giant tank on the grip and I can get into 60fpe or more then thats the gun for me even if it only does 1 mag a fill. I need something small and compact that can stop someone trying to hurt rob and or kill me. I litterally had 2 seperate sets of people try to beeak into 2 of my cars over the courze of the last 5 hours. So I kinda need the aea defender or if this gun is lethal enough this gun cus I can afford it. I'm saving to get a B&W s45 semi auto pcp. It's doing a cool 300+fpe with 200grain .457 slugs. It's 6 shot mags, 3-4 mags a fill, foldable stock, 22in long with stock off or folded and you can get a shorter barrel to make the whole thing only 17in long and still put out 200-250fpe you can also get barrel and mags to shoot in .357 if you want to. That's the ultimate self defense airgun. It's LITTERALLY as powerfull as a 45acp carbine but super expensive. Plus not something I can carry around. The aea defender is tiny but still 45cal 75fpe and theh have nice CCW waist holsters why I need a pistol that's small enough to bring with me but stronf enough to defend my home and life with. Once I have a s45 that just stays at home, I'll print a new magazine with 18 round capacity and I'll be good to go.

I want to convert my HDR68 to HPA.. But I don't want the tank hanging off the grip. I wonder if there's a way to attach a small airsoft tank to the underside of the barrel using a picatinny mount 🤷‍♂️ I have seen a bunch of m17s with the tank mounted on the top or the side..

where did you get the aluminum barrel for you hdr68

Hey brother is 1100psi output to much for hdr68

Hi can you please share with me what o'rings and size you replace on hdr68 to the nozzle of the pin valve?

On peut laisser combien de temp le gaz dans la bouteil sans percuter le hdr

Do you think this airgun can handle 1800 psi?
