Over-thinking recoil???

Postby freema22 » Tue Feb 22, 2011 10:08 pm

FIRST POST!

Howdy guys. I ordered my 450 Bushy upper from Cabela's, and I am planning my lower build. This is my first post here, but I have been a member at ARFCOM since 2004.

I'm getting ready to order parts for my lower and I am taking the recoil into consideration. Everyone says that the Thumper kicks like a 12 gauge. That is not a big deal to me, but I read lots of threads about recoil reduction.

Should I install a hydraulic buffer in mine or is a regular buffer spring just fine? I've never used a hydraulic buffer before, but I would consider it for this build. What is some first hand advice?

Thanks,
Mike F

I don't know about everyone else but, for me the recoil is nominal and needs no compensator or recoil reduction. It is no where near as stout as a 12 gauge, maybe about like a 20 gauge. My 300 WSM Browning A-Bolt recoils a lot harder with 180 grain bullets.
I had thought about a muzzle brake until I fired mine (16 inch upper). My suggestion is to shoot yours first and then decide about recoil reducers.

+1 with the advice of the Sims Limbsaver slip-on pad. It's the one thing that I have that makes the greatest difference. If you end up not needing it, you can use it on a more stout weapon.

I use two configurations:
1) carbine with A2 stock, normal buffer, normal buffer spring,rubber recoil pad
2) carbine with 6 position collapsible stock, Enidine hydraulic buffer, rubber recoil pad

I experienced a left by 4" zero shift when the recoil pad was added.
Recoil pad helps when zeroing off of the bench.
Hydraulic buffer provides greater resistance which cause more difficulty when manually locking the bolt open. If you are really familiar with the amount of force necessary to manually lock the bolt open, the extra force required by the hydraulic buffer can throw you off.
Both configurations work. I probably won't go with the hydraulic buffer again but I'm not taking it out of the carbine it's in.
When you have to shoot, shoot, don't talk.

Welcome! I have done some work with Recoil reducers,Muzzel brakes and recoil pads. With some success. 30% reduction.
I have not tested buffers as yet. They are next on the list.
"Hoot" has done some work with weighted carriers with positive results.
I know some here have tried hydrolic buffers. But, I Don't recall the results. Anyone want to chime in on this? Maybe add a comment to the recoil thead?

20ga. 12ga. After about 20 rounds, It's not fun anymore. It was time to do something about it. :D

I also have the Limbsaver slip on pad and it helps a lot.. It also helps to have a collapsable stock because the pad is quite thick.. Also it helps to adjust the pull length with different types of coats you may wear

the 450B has a unique kick/recoil to it.. Where my 308 bolt action is a quick, sharp recoil, the 450B (to me) seems like a slow push..

I put a Magpul CTR stock on mine and had originally considered putting on some sort of recoil pad. After shooting it I realize it's not needed. I let everyone at the range fire of a round and the consensus is the same. This gun's recoil is barely noticeable. 12 gauge? Maybe a .410/20 gauge target load at the max. I have a Marlin Guide gun in 45-70, that rifle has some punch. So does my Saiga 12 when I'm dumping 10 3" Magnum slugs down range.

Welcome to the forum! My 20 inch Bushy kicks about like a dove load for a 20 gauge. And after I get finished with my new lower build, its gonna be like a 7.62 x 39.
I will be using the Recoiless Stock Limbsaver pad and the custom reducer. See Recoil and what to do about it thread. I will be using a standard buffer spring with
an enidine buffer.
Update 2/28/2011
I will not be using the Enidine Buffer for now, but might later
begin to experiment with these type buffers.

This link is educational. Check out some of the recent R&D and discussions on recoil.

And Freema22, since your thread is discussing recoil, I have added a link to your thread

LOL!! Once again, this is our Tex-SD in action, LOL!!! I've been way to busy to come up here, much and the first thing I read is 'ol tex going at it, LoL [quote]

Indeed, Welcome 22 and "What Tex said", but where are the Somores!!!

I wouldn't do much with the buffers, that work is more for the Match guys or the Professional folks trying to slow down the system and if used by us, can make this system problematic, for it is designed for the standard AR goodies.

We can have all sorts of thoughts about recoil, but waiting until you shoot it is the best advise. Now, after that, if'n you need them, the Gunny (gunnut) has the fixes. I for one don't have a terrible problem with recoil, but I don't like it either. Gunnies system just plane works, but most of all for me, is that, On-Target fast follow-up shots, are made WAY better with his system and this is exceedingly important if you've got some kind of a critter, trying to stomp a mud hole into your Took-us..t
