Looks like an LMT bolt with lower fit and finish quality.

what advantages does your new cam pin provide over the std. ones?

Same question here.

The bolt does look like the LMT, excepte parked, (which isn't a downgrade, IMO), which has been hit and miss in performance, based on which setup you choose and which ammo you shoot.

For $120 I can have two brand new Bushmaster or RRA bolts. Will the ACB outlast two bolts from these manufacturers? What will it do in terms of performance that these bolts will not do?

Stainless steel? If I may ask, what series is this? Isn't carbon steel more wear resistant? These do look nice....kinda want one just for the sake of diversity.

Thanks!

How can you tell that by just looking at a picture?


LMT Koolaid?

Will this bolt work with all ammo, and all upper lengths?

LMT claims their bolt is designed for use with 62g M855 and 14.5" uppers.

I have not had an LMT one that worked properly, but I would like the dirt resistance of the bolt you have pictured for my M16.

Will the extractor still work with one broken spring and one intact spring?

Or does it require both springs intact to run?

Thinking about failure rates....

That's a very good question!

IIRC, the LMT Enhanced bolt wouldn't run with only one spring. If that's also the case with the LW bolt then I don't see how using the dual springs makes much difference from the standard single spring extractor.

How regularly do you need the springs replaces if at all? How easy is it to find replacement springs? What wear is evidenced on the extractor over time?

My 6.8 has broken a bolt. It sheared the lugs on both sides of the extractor. This design looks like it would help. Do you plan on making a 6.8 SPC version?

Yes, it is under development. We have some military 6.8SPC bolts in the same stainless steel currently in inventory. These are "standard configuration" bolts but use the better material and are identical to those issued to U.S. combat units.



I found a replacement but I'll be looking for one of your enhanced bolts wen they come out.

Thanks

We have not yet had to replace springs. Replacement springs are available from us or you can cut down (and grind the end of) AR selector springs in an emergency situation. We have seen no wear on the extractor itself, we use the standard material to make this part rather than stainless and have not yet seen a reason to change. It also keeps the cost down, you would not believe how much those extractors cost in terms of machining time.



Interesting. Might have to invest in one. Thanks for the input.

You had me at "available". I will take a 5.56 bolt now, a 6.8 bolt then and a handful of cam pins + a bag of extra springs.

In this picture I notice that in between the two srpings is a depression in the middle. One thing I wish the LMT had was the ability to use a standard extractor spring in case the two improved extractor springs failed. Now you can always carry spares but I have a billion standard extractor springs and one set of improved. It would be nice to be "backwards compatible"

Do you have any plans on making the improved bolt backwards compatible with standard extractor springs?

I've been around long enough to remember a bolt failure on my issue M16A-1(while I was wearing all cotton, non-camoflagued fatigues).

My shopping cart may be similiar, except for the 6.8 bolt. Need an email reply on how to handle the payment, though.

Um...you noticed that. This bolt was also designed to work with current inventory and be fully compatable with all platforms. The danger of anything proprietary is that in a crunch situation, the lack of back-up parts could pose serious problems. When we designed this bolt we were looking at a multi-faceted role, direct impingement, gas piston, light machine gun etc, so we incorporated everything into the bolt that made it perform better and then added some redundant features that would keep the weapon running no matter what. The depression you mention was designed to accept an extractor buffer that reduces extractor bounce in the LMG sustained fire role. It also happens that you can put a standard extractor spring there which will work (not recommended for general use) in an emergency. Features like this are incorporated into IP claims.

The same is true of our piston system; drive out the gas tube pin and reinsert the tube, change the carrier and you're back to direct impingement.



I have to notice things like that... if I don't it could be my life on the line when the clowns come.
