Why is the only CHF barrel a 1:12 twist instead of 1:10 like the rest of your barrels?
R Y on Aug 23, 2018
BEST ANSWER: To put more spin on the bullet because nato rounds are loaded hotter. The 7.62x51 nato chamberings they offer both come with 1:12 twist, this is the typical twist preference for this caliber as 1:7 is the standard for ar15
Can you use 308 ammo safely in this upper assembly?
franz on Jul 27, 2018
BEST ANSWER: Yes
Is the barrel stamped FN?
Dave on Aug 16, 2018
BEST ANSWER: No. "MP CHF 7.62 NATO 1/12"
This is a 7.62 NATO and therefore a .308 and NOT a 7.62x39? You're not being specific.
William D on Aug 2, 2018
BEST ANSWER: 7.62 x 51mm (NATO) and then 7.62 x 39mm (RUSSIAN). Russia isn't a NATO member the last time I checked....
It is mid or rifle length?
Thant T on Aug 6, 2018
BEST ANSWER: Read the title and the description, both say rifle length...
If this Barrel is not stamped Fabrique Nationale is it not then truly a barrel from them?
William K on Sep 1, 2018
BEST ANSWER: Believe me .. if they say fn It is fn .. I have one
description says M4 cut receiver AND barrel extension but one reviewer claims his extension is plain rifle cut.
have you addressed this problem, PSA?

Does the BCG have an enhanced firing pin?
Diego on Jul 31, 2018
BEST ANSWER: no, none needed. this is 7.62x51 NATO (308 Win.) and not 7.62x39 russian.
I want to make sure it's ok to use 308 win. hunting factory ammo ? I don't want a case to rupture. I would appreciate any help with this.
Andrew D on Mar 12, 2019
BEST ANSWER: It should be fine to use a quality brand of 308 win. In this. Just make sure you check the case and primer for abnormalities after shooting a few. The danger lies in guys who reload and put a normal 308 win load of powder which is hotter in a 7.62 NATO case. The walls are thicker in a 7.62 NATO case which could cause a rupture due to more pressure. Use proper reload in these. The main concern is with older 7.62 NATO rifles Which have more room in the chamber. The newer 7.62 NATO are closer in tolerance to the 308 win nowadays. Federal makes hunting rounds specifically for ar10 rifles called federal fusion msr.
Is the default gas block adjustable?
Ron L on Jan 20, 2019
BEST ANSWER: No. Its a basic low profile gas block
Will this fit a DPMS Oracle lower?
Matthew L on Nov 3, 2018
BEST ANSWER: No it will not... just buy a palmetto lower .. they are a great buy... excellent quality lower
What is the headspace measurement on this 7.62 nato upper? I want to make sure it's ok to use 308 win. hunting factory ammo in this. I don't want a case to rupture. I would appreciate any help with this. Thanks

Great barrel at this price point
Fits perfectly with the Gen 2 lower. Smooth operation and no failures with the 200 rounds I have put through it so far. It’s a solid weapon that weighs a little more than some will want to carry on foot walking for long distances. At 100 yards, it’s accurate enough for my needs. 1-1.5 inch groups once it was sighted in using base Federal ammo.

Awesome Rifle!
WOW! This rifle shoots! Very impressed. Fired about 100rds. No malfunctions. And I shot this group! I picked up the lower on sale and held out a few months for the CHF upper.

Feed ramps not correct
Just got this item, took apart to clean and oil, found the feed ramps have an issue. They are cut in a way that a lip is in the middle. Worried this is gonna cause trouble. Read elsewhere that psa fixed this by dremeling it out.... hope this can be corrected with some kind of decent machine work quality.

Shipping was glacier speed.

When i did take too the range for break in, i fired off single shots, and it went bang so that good so far.

This is the upper you have been waiting for!
Straight monster! Just a pure tack driver . MOA with surplus 7.62x51 ammo and close to half m.o.a. with handloads using 168 gr BTHP pushed by some varget . F&N barrel says it all . Does not work with DPMS style lowers . There is a clearance issue with the top of the buffer tube threaded area of the lower . You could grind it down for the charging handle to clear but why . This is my second P.S.A. upper and I wish I bought this one first . If you are looking at AR10 uppers you dont have to look any further .
