Does this upper # 516445940 have a triangle or round hand guard cap ?
Tyler G on Jun 27, 2018
BEST ANSWER: There appears to be a division on what style hand guard cap that comes with this upper. Mine came with a triangular cap which made me happy as I wanted to install triangular hand guards. I bought some aftermarket hand guards from a well-known parts supplier and they fit with NO problems whatsoever; if you know how to install them.
would this upper be classified as Hbar?
thomas b on Jul 22, 2018
BEST ANSWER: No, not HBAR, which would be a uniform diameter from the chamber forward. This is an A2 "profile" meaning it is actually a smaller diameter from the chamber to the gas block than the diameter forward of the gas block. I bought this configuration because I knew this rifle would be excessively heavy for my purposes and that the A2 profile would be somewhat lighter.

If a HBAR barrel is what you are looking for I believe this upper is available in that configuration. It's just not what you are currently looking at.
If I buy a spa bcg, will it drop right in and I can go shooting? Or do I need to do anything additional?
Sheldon C on Jul 2, 2018
BEST ANSWER: Psa bcg will work perfectly.
Why does this upper not accept any upgraded Mil-Spec charging handle ? I bought a BCM ambi CH and it would not fit. Just received a BCG and CH "PSA" brand combo. BCG works, but the CH is still to wide? This upper should accept most charging handles.

20 inch nitride
Love it! Put it on my first lower build. Added the nickel-boron BCG from PSA along with a PSA charging handle and carry handle. Shot about 30 rounds at the local indoor range to get on paper. Was concerned about having to adjust sights about 20 clicks right. Going to head to the CMP range soon and stretch it out. Would recommend to others.

As always fast and accurate
As always Palmetto hit the nail on the head. The delivery time was very fast. As well the fit and performance of this upper is no surprise. As I have ordered many PSA uppers and a few kits. Will definitely be ordering more parts soon

Great for an affordable CA Compliant M16 Build
Fired 500 rounds through mine and never skips a beat with a FailZero BCG. Shoots great though I need to still zero mine.
I really love this upper with my CA compliant M16A3 config. It always grabs attention at the range.

Exactly what I was looking for
Decided I wanted to do a modified A2 rifle. Purchased the PSA 20" for my Bushmaster carbine lower. The fit is incredible. It's tight and fits like they were made for each other. The finish is excellent and it looks good. I did change out the hand guards, I was inpatient to wait for the PSA 20" with the picattiny hand guards but it all worked out. Used Midwest Industries 2 piece hand guards. This is my first purchase from PSA but not my last. Service was quick and easy.
This is where I am so far. Haven't got a chance to fire it yet but I'm sure it will work flawlessly.
This was right after I placed it on the Bushmaster lower. I couldn't be anymore pleased.

Great for the price.
Inexpensive addition for DPMS lover. I've used it with a Weaver K-12 scope with good results.

Awesome product for the price if you're on a budget.
I've been wanting to make a budget A1 build, so I ordered both a 20in upper and A2 lower from PSA. I was glad to see the upper came with a triangle front cap so the repo A1 handguard slipped right into place in seconds. Took the rifle to the range and put around 200 rounds into it with no issues and was very accurate at 100+ yards with irons and Tula ammo.
I Ordered both the A2 PSA lower and 20in upper to make a budget A1. Worked great and looks great!
