My current setup is a Carbine Length Upper, with 16" barrel.

My stock is an ACE ARFX A2-length stock, with standard A2 rifle buffer, with a High Power Wolff spring.

My rifle feeds anything and everything. I've not had a single failure of any kind.

(Wolf, Tula, M193, M855... approx. 500 rounds mixed)

 

I find myself wanting a shorter LOP.

So, I'm currently searching for a good deal on an ACE Entry stock.

 

My question is, what changes will I experience in the cycling and felt recoil of my rifle, with a Carbine length Stock, Carbine length Spring and Standard Carbine Buffer?

Recoil will get harsher because you are moving to a lower weight buffer. If you find that objectionable, and since it has been running with a rifle length buffer, you can dig up a 5oz carbine buffer and it should remain closer to what you have. The lighter buffer will also mean a shorter delay before unlocking due to less mass. This will result in harsher ejection, probably putting bigger dents in the side of the brass adn chewing up the case rim more, and possibly ripping case rims off of softer cases.

 

One of my ARs is a 16" carbine length gas system with a full size ARFX stock. It has been very reliable on feeding, firing, and ejecting.

Everything raz-o said is on the money.

 

DTtuner if you want to get a shorter stock let me know and we may be able to work up a deal. I could use a A2 length stock.

Carbine - 3.0 oz

H - 3.8 oz

Spikes T2 - 4.3 oz

+1 Good stuff. Thank you.

 

I'd hate to lose the incredible reliability I've had with my current setup.

Maybe the grass just seems greener on the short LOP side

I saw this list on another site.

 

The question is....

 

What effect on cycle/performance does the Buffer have?

What effect on cycle/performance does the Spring have?

( +/- Stroke delay, Recoil, Feeding, Extraction, etc.? )

AS the weight increases, the longer the delay before unlocking, and the lower the cyclic rate. The lighter the weight, the harder it slams against the back of the tube, and the harder the BCG is slammed back into battery. It also gives you a slightly higher cyclic rate. A higher spring rate will soften the impact of the buffer to the rear, but will slam the BCG back into battery harder, This will trend towards less muzzle rise, but more muzzle dip when returning to battery. Too much spring and you will short stroke (no idea if anyone makes a buffer spring with THAT much increased spring rate). A lighter spring reverses that, and can lead to the system behaving as if over gassed. I don't think anyone sells a spring that light out of the box, but in theory starting with a lighter weight spring and then wearing it out could do that. Spring rate will not affect total cycle time, it will just change weather more time is spent absorbing recoil or returning to battery.

Thank you. Nice post.
