Hydraulic Buffer?

Smith is just recently gettin my personal attention...my personal collection has more HK than anything, my fav hangun to shoot has been my springfield, and now im diving into smiths...so far im liking the quality and performance...few more tweaks and i will be closer to ready for a full evaluation of her performance comparison :) (and no, unfortunately one of those tweaks isnt an acog...yet)

Dude you have major ACOG on the brain!

Lol for revolvers I dig my Smiths. Semi-autos.... I'm a glock guy.

$1097 at WallyWorld, impulse buy just after Thanksgiving. Was fortunate to go with my impulse that time, which is not always the case :)

Great price! Can I still have that dime? I'm hungry!! lol
 
Dude I so understand...I gave up being military when I got out, I want something comfortable and to my styling. If I wanted to look like I should be in uniform I could have stayed in the reserves, well maybe not this long. any There are some really sweet tactical guns here and right along beside them is something that you cant really shoot offhand. but we all learn from each other.

Alright tomorrow afternoon I shoot the buffer, I started to go shoot today but it started snowing. of course it quit when the sun went down. I get my mini-14 tomorrow so I will be doing some comparisons.

Funny.... Then you have the likes of me who never got the chance to serve but always ASKED if I'm military because I love my camo pants and sport a marine style haircut much of the time. Wonderful dichotomy! lol

One thing we certainly agree on is shooting! It snowed here today as well but Monday its supposed to be 52 on my day off. Hmmm what shall I do???
 
I wanna see pics of ur range visit with the rco and i wanna hear grover's impression of the ar-restor...my 10 pmag 20-rounders were at home waiting for me plus ranger plates and my sling adapter...gonna be a fun wknd
 
Sounds like we are all gunna have a good few days at the range. I really can't wait until spring.
 
The recoil in an AR is generated when the round goes off and during the time that the bolt is locked ....... which remains locked until after the projectile reaches the gas port.

The buffer/spring simply responds to reduce the inertia of the bolt moving to the rear 'after' the projectile has passed the gas port (which is properly sized to efficiently move the BCG rewards to unlock the bolt, clear the magazine and cock the hammer) and then provide the force to move the BCG forward again, strip off another round and relock the bolt.

More dampening provided by a heavier buffer, hydraulic buffer, and/or different spring strength combo's (and consequently changes in cycling) may result in a perception of reduced recoil and an actual reduction in muzzle lift, but it's really just the result of the action cycle timing and cushioning of the bolt itself's reaching the end of it's rearward momentum, anf then again when the bolt slams home again, and not actual recoil reduction.

It could stand to reason that this perception of buffer/spring induced recoil reduction (which once again .... is really just bolt cycling damping) should be more pronounced/noticeable in smaller caliber-lighter load combinations, and be more masked in larger caliber and heavier rounds.
I.e. .223 50 grain may resolve changes to the buffer system as more/less recoil, where it would be totally hidden in a 50 cal Beowulf.

But ..... the buffer and spring 'do not' and 'can not' impact recoil 'BECAUSE' ....... the bolt is locked during the time that the recoil is generated, and remains locked until the gas travels back to the piston/bolt and forces the bolt carrier to the rear, unlocking the bolt which then also travels rearward..... and only then does the buffer system come into play.
This is why when you have a valved gas port (like on single shot bench gun, or a piston and/or suppressed ARs) and you turn off the gas port (so the bolt remains locked/no cycling) ........ the recoil remains the same, sans the minor reduction of the BCG inertia that might be felt.

Different weight buffers and BCGs, as well as different strength springs are used to dampen the movement of, and optimize ..... BCG cycling with different loads in different gas system designs, with different BCG weights, and/or modified/supressed gas systems, etc. and can help reduce BCG movement induced muzzle lift ........ but they do not control recoil.

If you're looking to reduce recoil ........ and/or muzzle lift for that mater ..... and not able/wiling to go to a different length gas system (barrel) look into a brake that will accomplish what you want .... for the load you shoot.
You can help to control muzzle lift by tuning the the buffer system and/or BCG weight and using a tunable gas block.
You can also just add weight if that's OK with you and what you use your AR for.

I need a goooood heads up on that Mini. :D Thought you might have got a worse case of the flu. I'm still doing the step drag.... :D and semi mobile. My four legged little buddy keeps me on my toes. :D

They always told me it didn't rain/snow in the Army. It rained/snowed ON the Army. :D Any snow here under 7" we call a nuisance :D
 
Ha! It snows 2" here and people are screaming about the "white death" and flooding the grocery stores! LOL I grew up in Michigan as a kid. I know what real snow is. :)

So. Is it po-TA-toes or po-TAH-toes? ;)

No expert here but I always thought whatever action within a firearm that exerted rearward force to the shoulder or hand was in fact recoil. PO-TA-TO !!
 
I agree with Flyer91, I can find no fault in what he had to say but I also think that a moving part like the piston in the AR-restor can absorb some of that recoil and by damping can very conceivably reduce felt recoil. I dont think it is necessary to reduce the bolt going homes force because for proper shooting you are holding tight to your shoulder anyway.

And then there's those ones that kick like a mule. Felt recoil :D for every action there is a re-action. Simple.

:D "Taders" :D mashed taders,fried taders,taders & onions,taders & cheese......... they all come out the same in the end. :D
 
It is taders, but the energy stored in the rearward motion of the buffer is released in the forward motion and this hydraulic buffer lets it store more energy and by damping wastes off some of that energy.
