Mine was a little heavier than advertised I wanna say 1lb 10oz. And I also had to send it back because the flared profile on muzzle end was the same diameter as the gas journal and my gas block would not slide over it the tolerance was to tight and the beed blasted finish added a drag factor, I was gonna heat up the gas block to get it on but that’s a one way trip and I was thinking about coating the barrel. Anyway MRA has been pretty good about the whole deal, but I’m a little disappointed it didn’t work the first time and there turn around has been a little slow as I sent it back in the beginning of December and they haven’t fixed it yet.

Mine weighed 26.0 oz. I'd be curious if there is some variation with yours once you weigh it.

Wow that's 1.6lbs. Very light.

If you saw how thin the profile is you'd see why lol.

I'm interested to seeing how accurate it will be. No reports or reviews on MRA's pencil barrels from what I could find.

My experience with pencil barrels is that the first two shots are Sub MOA, after that they open up

No worries for a hunting rig , but if you plan on doing any target shooting for tiny groups, you’re gonna spend way to much timeWaiting for the barrel to cool down.

Thought I’d post some useless info, because I’m bored ha ha

I just assembled all my MS parts on a stag U/L.
CA CFW 20 inch barrel
True north brake( it works really welll).
BAD ridge line 15 inch handguard
Geiselle HSNM trigger
Maritime bolt catch
Brownells BCG
Brownells buffer tube assembly
Brownells butt stock
Raptor ambi CH

I’m going to change the Brownells aluminum butt stock for a CTR.
Should knock a few ounces off

Now I gotta switch it all back

Those will be nice rifles. August can't come fast enough.

I bought two complete receviers as well. Haven't decided on the second build yet, but the 7.62x39 is putting ideas in my head.

Since it seems to be the theme, I'll continue. Here's my MS part list list now that the last few parts have been ordered:

Upper: Slickside

Rifle will have a black and red theme to match my current guns and gear setup, but I'm in the second run so I'll have to continue to enjoy my ar15 for some time yet haha, no long range practice at my buddies farm.

[DILLIGAF]

Total weight 6.2 lbs.

here I thought my 7lbs was cool.... But mine is with sling and optic so I dont feel that bad... :-)

[Brianma65]

Well my optic is 20 ounces (VX3I LRP 4.5-14)
Not sure what the sling is ( MS3.. )

So that puts me at about 7.5.

So you still cool man
