Can I change out the handguard to the A1 triangular handguards?
Art E on Apr 23, 2018
BEST ANSWER: Yes you can. Back in the day many moons ago the Army didn’t have enough a2s in inventory so training units were issued m16a1s with a2 furniture installed to get basic trainees use to the feel of the weapon they would eventually be issued. My point is the triangular forearm retaining cap will work with both types.

BEST ANSWER: 1000 rounds of 223 ammo and the psa 20 inch a2 upper
If I buy this kit, will the only other things I need be a PSA AR-15 lower and a magazine? And ammo?
Thomas A on May 11, 2018
BEST ANSWER: Any mil-spec stripped lower should work. It does not have a rear iron sight so you'll need one of those or an optic to fire accurately, but functionally you only need this kit and a lower.
What is the difference in this kit and the 7788893B kit?

BEST ANSWER: Absolutely nothing other than cosmetic imperfections. The "B" stands for "Blemish"

I never got to use this rifle kit. The kit I received had large scratches in the upper receiver. I sent it back for an exchange after I a few days of no communication I called customer service only to hear it was out of stock and they didn’t know when it would be back in stock. The item was back in stock per psa’s website the next day. This wasn’t my first psa item, but it was my first time dealing with psa directly. I was highly disappointed in my experience and bought elsewhere. I give it 2 stars because the customer service was decent.

Outstanding Kit
This is my first kit, put together in the morning and shot it in the evening, put 150 rounds through it, no problem, recommend cleaning the BCG before you shoot, the stock was a light gray color, I covered it with a light coating of CLP and it became darker, staining it in a way, the rifle looks great and reminds me of the M16A2 I use to carry in the Corps, I would recommend this kit to anyone, i saw no blemishes, I got instructions on how to build it on Youtube, Outstanding product.

For a Retro build
The fit and finish on the upper is great and gets 5 starts but the lower parts kit I received was missing the rear take down pin, came with two front pins, and the roll pin for the bolt catch was a pain to get in. I dinged up the lower pretty good and this wasn't my first build so either I got the wrong roll pin or the PSA premium lower bolt catch pin channel was out of tolerance. Aside from that everything else was great except the A2 stock. There's a considerable wobble to it even after triple checking that it was installed properly. I think either the buffer tube may not be properly threaded or the stock screw I received is too long allowing for slop once it's installed. I'm not happy with the fit and finish on the lower parts kit.

Great price and kit. Add a grab handle and a triangle handguard and your looking like a vintage m16 for a fraction of the cost.

I bought this kit for a practice gun, I shoot on a military shooting team and we can not bring our M-16 home. It shoots great, good solid kit. Easy to put together.

Easy build, great functioning rifle
I wanted a rifle to compliment my carbine. The lower parts kit was sorted by component and was assembled on a stripped Anderson lower with minimum tools (punch set & hammer and a C clamp for installing roll pins).

The rifle shoots well and I am very happy with my purchase.
