HI need some help with my build ok I have a spr gun I built has a 18 in 223 Wilde barrel rifle length gas tube
I had a apex stock with standard weight buffer and spring A2 style shot 20 rounds though the gun ran flawless brass flew 6 ft back from 3 to 5 o'clock generally with hardly no kick I was thoroughly impressed with my first build Now I changed the butt stock to a carbine length 6 position B5 system for the summer I need to know what spring and buffer weight to run in this new stock to match as close to what I had in the other set up I have no way of weighing the a2 buffer so I need some help from all you gurus thank you very much |

I'd try a std carbine (3oz) and a spikes t2 (4 oz) and decide which you like better.
Rifle gas is going to make for a soft shooter regardless. I've got a t2 in my spr setup and I can't tell much difference. Same buffer in my mid-length carbine really smoothed it out. |
| With a carbine stock you have a carbine buffer tube. With a carbine buffer tube you must run a carbine buffer and carbine spring. The only question is which carbine buffer. Because of your rifle gas, I would suggest the standard unmarked buffer. You only need the heavy buffers for the shorter gas systems with stronger impulses. |

Standard rifle spring and standard rifle buffer (5.2 oz) = standard carbine spring and H6 carbine buffer (5.2 oz) I'm assuming you know that in a carbine length tube you use the carbine spring and shorter carbine buffer.
An H3 carbine buffer would probably work also, it weighs 5.4 oz. |

Damage Industries makes an excellent quality CS (carbon silicon) carbine spring for about $12. They are supposed to be good for like 500K cycles. Damage has 1/2 price sales fairly often on these springs if you check their website.
H6 carbine buffer weighs exactly the same as a std rifle buffer. H3 is .2 oz heavier. |
