Reviews & Ratings for JP Enterprises Jp-15/22R Upper Assembly — 5 reviews — Page 1

This item was received promptly. The packaging was insufficient such that the shipping brace for the bolt was broken into three pieces. So far the working part seems undamaged. The appearance, fit and finish are excellent. I attached it to a DDM4 lower for testing, with a Trijicon MRO on the rail. A S&W MP15-22 magazine in 10 rounds was included and worked well with the attached shim. I also got a Kriss 10 round mag to try--no shims required. I shot CCI minimags and Eley semi-auto benchrest outlaw from both magazines to zero the optic. Function was flawless, and accuracy improved over the first 20 or so rounds. This unit will not lock back on the last round without a specialized bolt catch (not supplied), meaning you will need a dedicated lower for this feature. All other AR features are functional making this a great low-cost training tool. Disassembly for cleaning is pretty straight forward. A sample of JB bore cleaner is also included in the package. Overall this appears to be a solid purchase. Hope this helps.

Of all the high end uppers I have this is probably the cleanest of them all...and it's a 22!
Haven't fitted the final glass yet but it's runs flawlessly and groups well.
Very impressive.

Very accurate and a high quality upper put it on and sight it in and had no problems or failures I was shooting quarter size groups at 50 yards I would recommend this product if you want a good accurate gun that’s a lot of fun hitting what you aiming at this is it and it looks great
