Questions & Answers
I have an Ar15 that while shooting unsuppressed is blowing back a ton gas to my face. Will a heavier buffer correct that issue?

A heavy buffer won’t stop gas blowback when suppressed. And a clean has tube will have little effect. You could try a charging handle designed to block the gas from going into your face, or you could get an adjustable gas block to limit the gas coming into the action. You will likely have to adjust it when changing from suppressed to unsuppressed.

How do I know what weight to use? 3 oz, 4oz or 5 oz? I'm using mine in a pistol. Expert Answer

That depends on a ton of variables including, but not limited to caliber, barrel length, gas system length, gas block style and ammo. It is always best to familiarize yourself with the firearm platform you are putting together and to understand the way an AR or any firearm actually functions. For most AR's an H-weight, which is usually around 3.8 ounces, is generally a good place to start. From there function testing the firearm will tell you whether you need a lighter or heavier buffer depending on the recoil impulse of the firearm, whether the firearm malfunctions and how the firearm is functioning in general.

Is it an h or an h2? Neither it's a T2! by Clayford, Verified Owner, November 11, 2019
Tungsten powder. No shakey noise. Ask what you should put in your mid-length gas system, and most will tell you get a spikes T2 and call it a day. It's that easy. Just get it. You might buy a new fancy single buffer/spring all in one thats super quie...
