Accu-strut 3?

Hi guys. Just musing out loud here. When I first joined the forum, interacted with a lot of great guys trying to eke out fractions of an inch on group size reduction. So when I designed the Accu-strut, and as someone who just hates wasted space, I designed an internal damper. But it's really a matter of diminishing returns, most of the barrel stabilization comes from the structural rigidity of the strut housing itself.

So what if I were to eliminate the dampener. Manufacturing costs would be much lower, and I could reduce the price of the unit. There would be weight savings as well. Any thoughts on this?

The upcoming Accu-strut Socom will be a short, undamped unit.

Kevin

Based upon the above . . . I would suggest eliminating the dampener.

Thank you for your input, Sticks. Now we'll see what my Mfg director thinks.

kkina,

Love your product...I own three of your original Accu-struts.

In fact, I'm a big advocate of the barrel strut concept, as you've probably read in my threads.

Anyway, here's my take...

If you can produce a quality product, at a cheaper cost...and offer it to your customers at a reasonably competitive price, I'd say why not forgo the dampening inside the strut?

From a production standpoint, I think you'd want to do a side-by-side test with an Accu-strut that has dampening, and one that doesn't.

Here's where I think your answer will lie.

Of course, everyone is going to say, "Yeah, sell it cheaper." But, as a producer, if you can prove that selling it cheaper, while lower your cost structure, does not affect the potential accuracy that much, then I'd say go for it.

Or, here's another idea...something very similar that you see for many other types of products...

Offer the Accu-strut with OR without dampening. Of course, the dampened model would cost more, but you would expand your marketing base by providing multiple options at different price points.

Hey...I just realized something...maybe I learned something at NIU's School of Business. LOL! =^)

Anyway, as believer in the concept and your product, I want to see you with much continued success.

As such, I hope my input helps.

Cheers, my friend. I hope this finds you well.

Good input.

I actually ran some tests a long time ago. while the damper shaves a little, maybe 10% off group, it's a question whether this is a big enough difference at the range to justify the cost. I mean we're not talking benchrest rifles here, we're talking our handy beloved little carbines and trying to prove we can shoot under 2-inch groups like the AR guy at the next bench over. But we want to do it with mimimal financial impact, I know many folks are hurting in this economy, not many people can afford professional gunsmith services, but say a bolt-on accurizing strut for well under $100 bucks (not sure till I get my directors report). I'm leaning toward saving money and weight It might also allow gb models to install a strut by hogging out a slot at the top accomodate the bayo lug.


well, here's the plan. The short Socom version is already under way should be available in a month. The next order could be for the Accu-strut 3 undamped, and we should have the final price worked out by then.

I'm very interested in a version that could me modified in order to attach to a GB model. I'd buy one today if you had them ready!

If we proceed with an undamped strut, which is basically a tube, I imagine anyone with basic machining skills could easily modify to accomodate that pesky bayonet lug

Definently interested... what type of weight savings are we talking about here? Between my 1st gen accu-strut, flashlight, and scout mounted aimpoint, my "little carbine" gets a little front heavy. Not a big deal until you have to carry it for an hour in armor to clear a building...

Not sure how much weight I can shave, but it will be noticeable. Busy right now with the Socom build, then can devote attention to Accu-strut 3.

kkina,

Right now, I'm contemplating using a barrel strut on my Mini's which has a three-point mounting system (like the Accu-strut 2).

Moreover, I like the concept of less weight with the new Accu-strut 3. Frankly, I'd forgo 10% in accuracy, so I can have a lighter rifle.

Good luck with the SOCOM build. Can't wait to see it.

Let us know about any new developments for the Accu-strut 3. You've definitely perked my interest.

Thanks!

Accu-strut 3 is a definite go. You'll be seeing it as "Accu-strut LT". I've already put in a manufacturing PO for it. It will probably supercede the A2 completely.

kkina,

Sounds good.

Thanks for the heads-up.

Cheers,
