Radical 458 upper
by Charles -
Very unhappy. Upper looks good but thats it. Will not chamber a round when you are able to get it to chamber it wont extract!!! ugh!
<br>Tried multiple ammo types and mags which is not cheap. Radical has not responded to email. Guess I chalk it up to a loss
Buyer Beware, only issues down this road!

<br>I have had huge issues with this .458 SOCOM upper, regardless of the brand of ammo or Magazine, the bolt jams, cases fail to eject and i have never managed to fire 2 rounds without issues, cursing and a red face at the range.
<br>Take care and consider other options.

Excellent product!!! I have this upper on a PSA lower and works flawless. Soft recoil.
Do Not Buy!!!!!!
Tried several different magazines 0 reliability
<br>Customer service at Primary Arms wasn’t horrible
<br>but referred me to Radical who absolutely SUCK
<br>I’ve purchased two uppers made by Radical through Primary
<br>Guaranteed there won’t be a third
I love my Radical Upper.
Unfortunately I did not buy it here and the place I bought mine from no longer carries these uppers. So I thought I'd leave my review here. The Radical is the best priced .458 SOCOM upper on the market bar none whether you find it on sale or regular price. I wish I had bought mine last year manufacturer direct when they had an Independence Day sale for $405, but snooze and lose. My only problem I'm having is FTF with snub nosed 300-350 grain "plinker" rounds. Seems the recoil knocks the rounds forward in my dedicated .458 magazines (with the non-sub 458 follower) and the get all wonky for some reason while feeding.
Rolling the dice with this one.

Could not get a round to chamber with several different mags. The bolt lugs would jam trying to lock up and then would be impossible to pull out using the charge handle. Had to use a hammer on the charging handle to get the bolt unstuck. The extracted bullet case was beat to hell with dings and dents from one attempted feed. I sent it back and the 2nd was a little better but still jammed 80% of the time. I took sandpaper to the bolt interfacing surfaces and it helped a lot. I then dry cycled the bolt about 500 times and there was more improvement. I would say this has to be a machining problem either on the bolt or barrel extension.

Only getting a 4 star because I hate the pickling oil! It actually smells like they used penit oil to pickle it. Anyway, 1st mag ran with a 5 jams 10 rounds a mag 2ed ran one jam out of 10 and 3rd mag no problem. Pretty accurate for a big ar throwing a big chunk of led! 100 yards I had no problems getting it in the 4inch circle and that was shooting as pretty fast trying to get a jam. Shoots pretty clean. I was surprised. Didn't brake the barrel in because I'm not looking for a tack driver just a quick down hog! I'm sure this baby will make me happy!
Cycles flawlessly, accurate, fit and finish is great
Do not buy
Do not buy this upper it is a piece of junck. I bought the 101/2" barell upper. Using the Lancer L5 magazines will not feed and the one that did feed cannot open bolt. I will stick with major names from now on
<br> A waste of money and hope their other products are worth the money. I should have read online reviews before I bought expensive lesson learned. No stars period.
Great upper! Great price! GREAT COMPANY TO WORK WITH!!!
by Walter -
All I can say is wow! I was price checking on line for rsomeone else and found this at one heck of a price. Got right on the phone and ordered it. Put it on an extra lower I had and it went bang, bang and I was grinning ear to ear! Get you one of these before they're gone and YOU miss out!

Runs great and is accurate.
458socom upper awesome
Awesome upper! My wife ordered this 458socom upper Friday morning in the am for Father's Day. It arrived Saturday at noon. It seemed impossible!!! I shot 20 rounds through it today using my 223/556 10rd magazine without a single jam!!! This upper is amazing and for the dollar you cannot beat it. Can't wait to order another upper or anything with primaryarms they are awesome.
Awesome Hunting Weapon
by Pro Sportsman -
My upper came with an out of spec bolt and would not function properly. Primary Arms helped me get this fixed by Radical Arms who also sent me a special magazine with the new bolt. I recently got to fire the weapon and it shot tight groups with bullets from 250g to 500g all going to within 5 inches of the same point of impact. This makes this a awesome hunting weapon that you do not have to re zero when you switch bullet weights. Even the 500g subsonics were on the vital zone at 50 yards using a zero for a 250g bullet.
Great upper and awesome round. Fit perfect and shot flawlessly. Great buy. Super fast shipping from primary arms.
Very bad quality. 100℅ failure rate.
Not good. Will not eject the spent shells at all ever. 100 % failure rate. Never two rounds fired in a row.
WASTE OF MONEY BUY WILSON OR RRA
MONEY WASTED PURCHASED SEVERAL MONTHS AGO. BOLT WAS RUSTED AND FROZEN TIGHT. BARREL WOULD NOT CHAMBER A ROUND BOLT WOULD GET STUCK MIDWAY UNLESS SLAMMED HARD BY FORCE THEN WOULD FREEZE IN BARREL. DO NOT BUY ENDED UP DESTROYING THE RAILS TRYING TO REMOVE THE BARREL NUT
