I am using an FA Bolt, Heavy Buffer by heavybuffer.com and a Wolff Extra Power Spring, I noticed it is quite heavy to pull the CH and the impact of the bolt when released is quite stronger.
Will these add to much faster wear on my upper receiver? I am planning to replace it with a Tubb CS Spring.
Any inputs, or comments? Thanks.
I don’t run a XP wolf buffer spring or a Tubbs cs buffer spring. I do use a tactical spring standard rate buffer spring the blue one. [http://www.sprinco.com/tactical.html ] If you are running a FA bolt and a heavy buffer you shouldn’t need a XP buffer spring if you wanted to slow down the BCG more I would try an H-2 buffer or one that is heavier than the H-2.
Are there any pssible damage it can bring to the firearm?
I don’t think it would break any thing but I would think it would put more wear on it than is necessary. If you are trying to improve reliability you are on the right track with the FA bcg and Heavy buffer. The main benefit of CS springs is that they take a set once and have a long service life and give consistent cycling through out there service life. If the carbine cycles reliably on a standard rate spring then changing to a XP spring is not going to make it even more reliable.
My M16 runs great with Wolf XP spring and 154 gram pistol buffer.

I’m runnung the Tubbs CS flatwire buffer spring with a FA bolt carrier, and ST-T2 buffer (filled with tungsten shot peen - weighs in a little heavier than a H2 buffer but has a much better dampening effect) and I love the combination… This is with an 18" midlength Sabre Defense barrel with a factory gas port. This combination works extremely well for me, my rifle is an extrememly smooth shooter that locks the bolt back every time. I hope this helps!
if it works 100% then leave it alone. the biggest problem here is people start tinkering with the gear just to buy cool stuff.
if it doesn’t work then find someone here(there a few) who use guns for a living. find out what they use in their life/death/duty guns and do like wise.
buying stuff for the coolness factor is wrong and detrimental to your health, in a crisis.
if the gun works leave it alone. i have changed 1 recoil buffer in 40 years of using these things because it was a 5.45+39 i dodnt know muchg about buffers and Grant told me to. for 391/2 yrs, arms room issue was o.k. with me.
Replace it with the Tubbs. Not only are they stronger and will most likely last thru your lifetime(depending on use) they are tuneable by cutting coils until the rig cycles efficiently.
I would never use a Tubbs or Wolff XP, I remember a thread on ARF where someone installed a Tubb spring and it caused a slam fire when he chambered a round in his garage. No thanks.
Thanks for the tip!
It’s a miracle that the M16 and five AR15’s I use with Wolf & Tubbs springs haven’t caused an accidental discharge yet!
Maybe it’s because I never put my finger on the trigger when dic:cool:king around with my guns in the garage? Or maybe it’s because I don’t let Bubba do my trigger jobs?
Don’t believe everything you read, let alone repeat it in public.
Have a nice day.

Not trying to frag your parade BUT=
Un-fuck the user, un-fuck the rig … its not the springs dude.
In the end, I dont eat you meals or tuck your kids in the bed so its all on you. Dont mind me and my SSS springs. I am sure “a guy on TOS” said SSS springs were shyt for bolt upgrades too… What do the IPs’ and “shooters” know anyway??
It’s not like it’s unbelievable. The AR firing pin is free floating, when you chamber a round it will sometimes dimple the primer. Using a heavier spring causes it to fly home with more force…
Not rocket science here, people.
The Tubbs website and the package insert says the force maybe less with one of their springs, go figure!
>>“Since the bolt carrier returns to battery at a lower velocity, there is less rifle
movement, and that means less sight movement”<<

I have never heard of anyone having a slam fire because of any extra power spring. Just allegedly having 20% more force is not enough to set off the primer. The margin of safety is not that tight.

For guys running an SBR or can or both I can see the usefulness in a XP spring .Because of increased bolt velocity with the extra gas you would have but if you have neither why bother has you pointed out the BCG will be returning to battery with less velocity and less sight movement. If there is sufficient force with the standard rate buffer spring to reliably cycle BCG with your rifle I don’t see it improving reliability even more by just upping the spring rate.
Agree with the SBR/can statement.
For a real AR15 with 18 or 20 inch barrel the standard spring & buffers are the way to go.

A standard spring may have been ok when this rifle was designed, but in 2010, there are much better choices for a buffer spring from a perspective of manufacturing, material choice, and design. When springs get out of spec (on any firearm) the timing and function suffer to the point of possible failures in its function. Why would someone not want to change a part of their rifle from something that has a life cycle of 6,000 to 8,000 rounds to say 50,000? The Tubbs flatwire spring can be adjusted to provide more or less tension than a stock spring depending upon your rifle’s needs and parts / build selection. I don’t see a drawback… With my particular rifle, I have it setup for absolute reliability and longevity. They’re alot of good parts options in the AR world, don’t be afraid to venture out and try them for yourself.
I was informed that the life of the Tubbs CS flatwire spring is like 500k… Basically, the “average” rigs’ life span…
Personally, these are a standard on all my lower builds.
