I recently got my Gunslinger 2 with accessories from Ceylon @ Deltaoutdoorsman.com. I purchased the Endo frame to use with my pack.

Let me say right off that it's a neat idea and it does work. The Endo frame certainly stiffens up the pack and makes it feel better on your back.

A couple things became readily apparent. The frame doesn't want to stay where it should unless you always keep your pack stuffed full, thus keeping the Endo frame in place up against the interior wall. Even when full, since it's not secured in place, it tends to float around some.

Eberlestock has room for improvement with the Endo frame. Adding velcro tabs to the interior to hold the frame in place would be one option. Another would be to allow access to the frame sheet via a velcro closed flap on top allowing the frame to be inserted or removed..... maybe in future generations?

I don't always leave the house with my pack stuffed to the gills, but given the light weight of the Endo frame, I'd like to be able to just leave it in place all the time and have it stay where it's supposed to.

I appologize in advance for lack of pictures, but here's what I came up with.

Starting with the pack completely empty, I inserted the Endo frame making sure it was in place. You'll notice that approximately the center 1/3 (sides of the frame) runs right along a row of the molle loops on the inside side wall of the big compartment. I marked the Endo with a dot from a sharpie just under the lowest molle loop.

I cut about 18" of para cord, melted both ends and dressed them up. Now you can remove the Endo frame from the pack. Place the para cord end at your mark with the trailing end running down towards the bottom of the frame. Take a piece of duct tape about 3/4" wide x 6" long and go around the frame and over the para cord once. Now take the para cord trailing end and pull or lay it over the duct tape so the end is at the top of the frame. Finish wrapping the duct tape around the frame and 2 layers of para cord. What you've created here is basically a lock to secure the para cord to the frame so it won't slide or pull out. Repeat this for the other side of the frame with another length of para cord. When both sides are done, put frame back into pack. If done correctly, your paracord anchor point will be just below the lowest row of molle loops.

With frame in place, run the trailing end of the cord through the first molle loop taking out any slack. Now take a turn around the Endo frame, then go through the next molle loop, then another turn around the frame. Repeat this until you pass cord through the highest molle loop. At this point, stop and work out any slack you have, starting at your anchor working up. It should be snug, not mongo tight. You just want to hold the frame in place, but not put any unnecessary strain on the molle loops. I did this in such a way so that the molle loops weren't bunched up at all, they lay flat.

Ok, slack worked out, now tie a clove hitch around the frame just clearing the top molle loop.

With the cord you have left, go over the top of the highest molle loop (you're now working top to bottom), then around the frame once, then through the next lower molle loop, and another turn around the frame. Repeat this until you've worked back to where you made your anchor. Work out any slack and finish off with another clove hitch and tie off the trailing end however you wish.

This whole project took me about 20 minutes to come up with start to finish. It's not permanent, does no damage to frame or pack, and can easily be undone. It keeps the frame in place and doesn't hinder really cranking down on your compression straps (the reason I only went snug on the para cord).

Small zip ties might work too, but I decided against that method since once you cut off the tail of a zip tie you could end up with a sharp edge that could wear on the pack fabric.

After a few days use, this seems to be working quite well. The frame hasn't moved up/down and it's held to the inside wall of the pack where it belongs.

Hopefully someone else may benefit also.
 
Re: Securing Endo frame in Eberlestock packs

nice idea mp15. i noticed the same problem when i dropped the endo frame into my gs2 - started to look for some some loops that supposedly hold the frame, but there are none.

a few sewed velcro loops on the inside (next generation gs2?) would really notably increase the worth/usability of the frame.

that's maybe the first item/feature so far by eberlestock does not seem to be thoroughly thought through. all their other stuff just is plain, simple and works. the endo-frame rather seems to be an idea without the necessary usability (lacking the attachment points in the packs).
 
Re: Securing Endo frame in Eberlestock packs

Threetrees,

I agree 100% with what you said. If they added a flap on top of the frame sheet compartment like my 5.11 Rush 72 pack has so you could slip the endo frame in there, it would work really well and give the user the option to have it in place or remove it.

As it is, it really sort of sucks, but lashing it in place seems to make a half thought out product work.

Another fix for the next generation would be to sew triangle tuck pockets in all 4 corners, and add a velcro loop about 1/2 way down on each side. You are right, the idea is there, they just didn't execute it all that well before release.

A little "redneck engineering" with some paracord does a pretty decent job. If you have time, try it and let me know what you think. It's not 100% perfect, but what the hell else a guy gonna do with the frame?
 
Re: Securing Endo frame in Eberlestock packs

How do the frames work when you have a rifle in the pack?

Is the frame forced to bend around the rifle?
 
Re: Securing Endo frame in Eberlestock packs

Honestly I haven't tried that yet. I suppose if one really went to town on the compression straps anything is possible. If you are reasonable about tightening things down I would think it would be ok since you have the plastic frame sheet that's sewn inside the back wall of the pack + the Endo frame.
 
Re: Securing Endo frame in Eberlestock packs

Upon further use and inspection of a buddies Operator pack, I have come to a couple realizations which has clarified a couple things for me as I was mistaken in my thinking......

The Operator or any of the other packs which have the bendable or user fit-able stays and frame sheet combo are both right behind the harness which would be all on one side (closests to the wearer's back) of the weapons pocket.

The Gunslinger 2 and other models that can utilize the Endo frame have a frame sheet sewn inside the panel of the weapons pocket that rides right behind the harness on the weapons pocket. When using the Endo frame, you are putting this in main load space of the pack on the "other" side or back side of the weapons pocket.

If anything, the Endo frame provides some structure to the opening of the weapons pocket on the load space side on the top and the bottom. The upper and lower compression straps cross the frame approx. 1/4 the way down from top and 1/4 the way up on the bottom.

I put my Savage 10PC with SS scope and altlas bipod in the weapons pocket w/Endo frame in place. If one uses the compression straps going through the loops to compress the scabbard there is no frame bending, however the rifle is in there quite securely. If access to the rifle is important, I think I'd run the compression straps without using the loops and just compress the main load.

The Endo frame is not the end all be all accessory. It is very light weight so having it lashed in place all the time really isn't something a person would think twice about. It does help make up for the pack not having adjustable stays, though not quite as well. If you've ever used a Eberlestock pack that has the stays and have experienced how well you can customize the fit and comfort for your load, you'll see what the difference is.

The Endo does help take out the "slouch" that many users experience. At the end of the day, I'd have to conclude that it does improve the pack's performance marginally. I have it, and will use it. If you pack heavy and hate the slouch that you can sometimes get in a Gunslinger, give one a try. If you can live without it, waiting until Eberlestock puts further thought and development into it's implementation might be a better option.

If you can find the Endo on sale, it's a cheap accessory to try. Just don't expect that you are converting to a full frame pack or the Eberlestock models with the stays.
 
Re: Securing Endo frame in Eberlestock packs

thanks for the feedback, I was gonna get one for my GS2 but I will wait to see if they come up with an improved version. My GS2 is always loaded to the max and it would be nice to have a rigid frame to get rid of the "slouch" but no big deal.
 
Re: Securing Endo frame in Eberlestock packs

Good stuff here, REAL world feedback is valuable. I completely agree that the ENDO internal frame is an accessory that shows promise. What I tell most who ask about it's performance & function is to pass on it unless you forsee yourself running MAX CAPACITY loads frequently and need the added rigidity. It does help with the "slouch" issue that can sometimes creep up, but it doesn't completely eliminate this issue. Overall, it is a good add on if you're looking for added stability with large loads, but isn't a "game changer" in this regard.

The issues with the frame just resting within the pack (no installation or method to keep in in place; just friction) has been brought up with Glen Eberle. I have no info to share as to whether a design upgrade is in the works, but he will take these observations & opinions to heart. If I hear something in this regard, I promise to share it here first!

Re: Securing Endo frame in Eberlestock packs

If you've got a sewing machine and some Velcro you can easily fix it in the pack with about 5 minutes worth of work.

Take about 1 1/2" of both male and female Velcro and sew it end to end so when you wrap it around the Endo frame it sticks to itself. Make 8 of these.

Sew 2 each to the end of a piece of webbing, MOLLE-sized width apart. It will look like an I or an H, depending in your preference of letter.

Slip one end through the webbing inside the backpack in 4 spots where you wish to secure the frame.

Insert frame into pack and secure with Velcro. By using Velcro above and below a single MOLLE row, it prevents your homemade tie-downs from slipping through the webbing were one to come undone or removal of the frame from the pack.

Essentially you're making a Velcro version of the BFG Tourniquet Now! Strap, although smaller and adjustable for however tight you want the frame.
 
Re: Securing Endo frame in Eberlestock packs

Thanks for dropping in on the thread Ceylon. Hopefully Glen can make some improvements down the road. As it is, the Endo is working out quite well considering the noted short comings. Even though it's only needed for max. loads, it's growing on me and I'll be leaving it in place most of the time. It only takes a couple minutes to lash in place or unlash and remove.

As suggested above, para cord or velcro does take it to the next level.

Actually, any of the packs that have the built in gun pocket/scabbard, with stays or without will tend to have a "loose" feeling unless you crank down on the compression straps enough.
 
Re: Securing Endo frame in Eberlestock packs

Thanks for posting about this. Just got my Lodrag and Endo from Ceylon two days ago. I opened box in front of two coworkers. We spent 10 minutes looking at the pack from every angle trying to figure out how to install the Endo frame. It didn't seem right that it just sits in the main compartment. I guess it does though...

I really wish the design was something like Osprey is putting in their packs now. They have a light metal frame similar to the Endo that is sewn into the pack and makes the pack very ridgid. The frame sits close to the users back and it is load bearing. Wonderful design. Of course Osprey packs don't come in multicam, are made of light nylon and definitely don't have a gun scabbard.
 
Re: Securing Endo frame in Eberlestock packs

Anyone got pics of this frame in the pack? I just got my gunslinger2 today. It is really a well made, well thought out piece of gear but i too see a few things that could be improved.
