LMT MWS slashs buffer/spring question.

[Evol ways]

So I just recieved my slashs car10 and carbine length upgraded spring and noticed there is a huge diffrence in the spring length. Here is a picture of the new (bottem) and stock spring (top). My question is, is this correct? I installed it and ran the charging handle and it feels alot smoother then the stock feel but unsure if that's due to the short spring. Thanks guys.

The difference in buffer lengths makes me nervous there. If your BCG stops on the gas key instead of the buffer hitting bottom you are in deep shit.

One spring is much more dense/stronger than the other. I have 2 set ups like yours and lierally have not had 1 malfunction in either the MWS or LM8MWS. Keep your original spring and buffer as a spare/back up and call it a day.

BTW; I only shoot good ammo. I don't shoot surplus or underpowered ammo.

Shoot that thing and let us know how much you like it Evol! (It's not a bad idea to put some light lube on your spring and buffer while you have it out as well)

The slash buffer and spring combo on the bottom is for use in a standard buffer tube. The LMT MWS has a AR10 length buffer tube which is slightly longer than the standard buffer tube, you should continue using the spring and buffer it came with unless you have changed buffer tubes.

I hope this clears up the confusion...

The CAR-10/CAR-10 XH buffers are designed to be used with a standard 7" carbine receiver extension. If the top buffer in your pic came out of the MWS then it has a 7-3/4" VLTOR/ArmaLite receiver extension.

With the extended tube I recommend an XH carbine buffer (8.5 oz) and a .308 rifle buffer spring.

Sorry for the inconvenience.

More info on the buffer here: XH Carbine Buffer
(I don't know how the rules work here as far as posting links but I'm sure someone will clobber me up side the head if I'm out of line.)

FWIW, you absolutely cannot compare springs by just measuring their relaxed length. The total number of coils and wire diameter are the determining factors in relative spring strength.

Slash, yea I was told by a fellow member that LMT's run the 7 3/4" tube, my fault for not double checking.

I just sent you a email.

Could you please explain why this set up, carbine buffer and rifle length spring, is needed in this case. I thought you wanted to have carbine/ carbine components and vice versa. Thanks for the help.

Clint Had me go with the XH Carbine Buffer and it works wonders. He is the man when it comes to springs and buffers i'll always upgrade to his ...

 

[Slash]

Until I started make CAR-10 buffers, there was no such thing as a .308 carbine spring - All .308s used rifle springs regardless of the configuration (and there also was no way to use a standard 7" carbine buffer tube on a .308 AR).

The shorter buffer requires a different spring because a fully compressed .308 rifle buffer spring is actually longer than a CAR-10 buffer.

I hope that this makes sense. Let me know if you have any further questions.

I was just wondering if you could go into details about how changing the buffer and spring improved the existing. Just more smooth or more accurate? Just wondering.

well i went with it because i changed out the stock from the standard that comes on the LMT MWS to a UBR and i feel it is really just more smoth it helps a bit with the recoil
