Radical Arms 10.5" MLOK Upper

[UWone77]

Used 3 additional mags, same problems. Won't extract. Will try another non-Radical BCG next time. So far this upper has been a bust. You get what you pay for.

When you get the fired round out of the chamber does it have extractor marks?

I was curious as well


Uw - before you swap bcgs , maybe swap the extractor spring and/ or insert or o-ring

I’ve swapped in a few bcm extractor springs/ Black inserts in some finicky rifles and it seemed to fix it

Exactly!

So after I had initial issues with this project, I took it out twice more since the last update. I know it's been awhile, but I've been zero'ing a lot of other guns, so it's taken a back seat.

I've shot another 320 rounds through the upper and the last 260 rounds have been trouble free. I'm going to attribute this to a break in period for this upper. I haven't done anything to trouble shoot it as far as swapping BCG's, extractor springs, ect. I took it apart after my initial troubles and thoroughly cleaned and lubed everything. I then reassembled and still had some sporadic issues.

I again cleaned and lubed everything and the last 8 mags or so have been trouble free. I'll take it out a few more times to see if the upper continues to function correctly. The only variable I changed was I used 2 fresh out of the wrapper Magpul MOE PMags.

UW, what say you?

[UWone77]

For $159, I say go for it Jerry, as you're knowledgeable enough with the platform to trouble shoot. If you were a new shooter, I'd say no.

Wow that price! I need an extra upper like I need an extra head, but damn!

I'd just get the barrel for $90 https://www.primaryarms.com/radical-...avy-profile-18 That way you're not stuck with someone else's choices for handguard and MD

On a side note, anyone local to Rainier, I just noticed in the storefront they have used take off Rainier Mountain barrels for $50.

On the discount table? Nuts, I'm leaving town tomorrow. Think they'd accept a call-in order for one?

No idea, but probably worth a 5 min call to find out!

Was at RA today to take care of a Form 4 and they still had a few of these so I picked one up. They all had definitely seen some use but for $50 I went ahead an grabbed one. They weren't marked but I figured they were maybe 14.5" barrels, but it turns out they are actually closer to 13.5" barrels. I don't believe they ever sold them that way, so I'm guessing they were local PD contract guns.

Correct, these were Renton PD guns they took apart. The barrels were cut down to 13.5" to make them work with a certain handguard and an OSS suppressor.

It ended up being a perfect cut for an Aero Precision ATLAS 12" handguard (which is around 12.6"). Too bad it isn't middy gas, though.
