BOLTS ARE NOT INCLUDED with a barrel. They are an option either below the barrel description or on the 'bolt/carrier"page.
Barrels are ported to work with standard carbine springs and buffers when used with Normal ammo producing 54000psi. Using weak ammo, heavier buffers or stronger spring may cause the rifle to short stroke or not strip ammo from the mag.
The gas block boss on the barrels are sized to work with .750 diameter gas blocks, that does NOT mean the boss itself is exactly .750.
Many in the spec ops think the M4 14.5 barrels are too long for use with a suppressor. They also think they lose too much velocity with the MK18 10" barrels. These 12.5" barrels were our answer. These barrels have a mid gas system to help cut down on problems associated with carbine length gas systems and suppressors. All barrels ship flat rate $15
Due Oct 2018
18" SPR contour with a rifle length gas system to soften the recoil impulse for the fastest follow up shots. Perfect for 3 gun or PRS-tactical light. Twist rate will work with bullets from 40-80gr. 11 degree crown with threaded muzzle. It will not effect accuracy with the light 40gr bullets.
NOTICE- This barrel has 5/8-24 muzzle threads to reduce bore swelling at the muzzle common with barrels threaded 1/2-28. Most barrels with 1/2" muzzle threads will allow bullets to wobble when exiting the muzzle which degrades accuracy.

We're in business for the 50% of this country that are tired of the corrupt democratic way, the Deplorables, Patriots, Infidels, protectors of the US Constitution, flag and President. We applaud the 50% who refused to let Hillary destroy this country.
