Please discuss what you think are the top 3 to use with your carrier, why and adjustments that may be needed.   I am thinking of an ultralight build but have never messed with the gas.

The adjustable gas block we recommend is the SLR.  It has the best adjustment design on the market.  It is also low profile and will fit under almost any handguard.

Using an adjustable gas block will allow you to fine tune the rifle to your needs.

I have a light weight 20" rifle gassed barrel with non adjustable gas block with a rifle buffer & spring.

Can I run your carrier using varmint loads and 45grain bullets as well as 55 grain fmg mil surp.

I see Jesse and the guys running 18" rifle gassed barrels with carbine length buffer tubes (not sure what wt buffers they use) but
that seems to run well.

Have you guys done enough experimentation with various springs and buffer weights to make recommendations?

Thanks in advance

Just a standard carbine spring and 3.0 oz carbine buffer seems to be the best setup overall.

You can run anything from  40 gr bullets up to 77 gr, we've tried them all.  Mil ammo is fine although hotter than what you need for many hoser type matches.

many thanks
