AR15's - direct impingement vs gas piston

[QuangTri]

Good to know.

Having started with rifles cleaning the M14 and then having to deal with the filthy bolt carrier of ARs has always had me interested in piston conversions.

Now if someone will come up with a big block piston kit.

Adams Arms is back, Alexandria Pro Fab purchased everything they had. Said they will honor the lifetime warranties on all AA firearms, plus the availability of parts now.
Coming soon to Alex Pro Fab web site

This is definitely great news! Thank you for sharing!
